RINGER/MESSAGE WAITING INDICATOR  
Located at the top right hand side of the telephone above the DISPLAY, the red lense  
contains two different indicators; their functions are as follows:  
1. Ring Indicator  
Flashes when the telephone rings with an  
incoming call.  
2. PABX Message Waiting Indicator Illuminates when a message is waiting in your  
PABX voicemail system (depends on system  
compatibility). The built-in Message Waiting  
option suits any neon type (minimum 80 VDC)  
message waiting system and Ericsson BP250  
Message Waiting (other system types are available  
as optional extras). To determine which PABX type  
your IQ750 has been prepared to suit,  
check the telephone’s underside for a label indicating that specific circuitry has been  
installed in your unit. If in doubt, contact Interquartz for further details. To retrieve your  
message, consult your voice mail system user guide.  
IQ750 is also fitted with a message waiting indicator lamp which is compatible with the  
voicemailfeaturesofCentrexnetworks(eg.TelstraCustomnet)andresidentiallinevoicemail  
systems (eg. Telstra Home Messages 101 and MessageBank). There are indicators  
located in the CALLER Key and display for these services and are described elsewhere  
in this manual.  
RINGER VOLUME SWITCH  
The three available positions allow selection of OFF (no sound), LOW volume, and HIGH  
volume of the telephone ringing sound during an incoming call (Figure 2B).  
RINGER PITCH CONTROL  
The pitch of the ringing sound may be altered by rotating the control to suit your preference  
to achieve a distinctive sound, or one that is audible, more distinctive or more pleasant.  
12  
 
ALPHA-NUMERIC KEYPAD  
In addition to normal dialling, the alphabetic characters are provided on the keys to enter  
names in the Direct Access and Directory memories as well as any online applications  
that require alphabetic keystrokes.  
RESET KEY  
Press to restore normal operation of the telephone in case of a malfunction or lock-up.  
The memories will not be erased when this key is pressed.  
CRADLE SWITCH  
Located in the handset cradle, this plastic lever is depressed by the Handset (when  
placed in the cradle) to cut off the line. Note: Depressing this cradle lever too briefly when  
intending to terminate a call may result in an accidental “hookflash” that will inadvertently  
place the call on hold - this is known as “phantom calls” because the held call may ring  
again at your extension within a few minutes (the other party will have hung up, so it will  
seem as if you were called by a phantom, hence the name “phantom calls”). If you  
experience this problem, when terminating your call please depress the cradle lever a  
little longer before making/receiving your next call (i.e. phantom calls are not a system  
or telephone fault).  
VOLUME SLIDER  
Used to adjust the hearing level of the Handset Earpiece/Handsfree Speaker/Headset.  
Set to midway for normal listening level. Adjustment during a conversation will not be  
detected by the other party.  
RECALL KEY  
For use with PABX systems to invoke special PABX facilities such as call-hold or call  
transfer which may be available in your PABX. It is sometimes referred to as the “Flash”  
Key or “Facility” Key. To learn how to use it, please consult your telephone host system  
manual. Recall timing is preset to 100mS. The Recall Timing setting affects the Recall  
Key’s ability to function correctly with your system (see the Installation section regarding  
this setting).  
13  
 
REDIAL KEY  
Press to redial the last number last dialed, which may be up to 32 digits long. When  
pressed while still on-line, the telephone will clear the call and retry the number. It can be  
used in Handset, Handsfree, and Headset modes. Dialing more than 32 digits during one  
call will cause erasure of the entire number from the Redial Memory.  
See further details of the 5-stack Last Number Redial Memory in section 6 “Memory  
Operation”.  
To redial last number  
1. Lift Handset, or press HANDSFREE/HEADSET

2. Dial a number, [unsuccessful]  
3. Press REDIAL; the telephone will automatically clear and re-connect the line; the  
number will be re-dialed.  
PAUSE FUNCTION  
The Pause command may be needed if your phone is connected to certain types of  
PABX or to any network where a momentary pause is required (e.g. between internal and  
external dial tones).  
For manual dialing:  
1. Lift Handset  
2. Dial any digits required before the pause  
3. Press PAUSE; the telephone will complete the dialing process once the Pause  
time has elapsed

15  
 
BATTERY COMPARTMENT  
As a precaution against the potential for an interruption of mains power to affect the  
progress of any ongoing call, 4 x AA alkaline batteries can be fitted to the compartment  
(they can provide up to one month’s support of all functions while mains power is absent).  
However, while mains power is present, battery power will not be consumed. If batteries  
have been fitted, it is recommended that they be routinely replaced before the “best  
before” date indicated by the battery manufacturer (consult the packaging or check on  
the battery).

18  
 
HINTS FOR HANDSFREE OPERATION  
As a courtesy, tell the other party that you are using the Handsfree function. He/She  
may or may not want people other than you to hear the conversation. Aquiet environment  
ensures best Handsfree performance. When Handsfree is used in a noisy room or near a  
noise generating device (for example, a TV set), all or part of the message may be  
interrupted and cannot be heard. To eliminate this problem, try to lower the noise level in  
the room.  
During the Handsfree conversation, your telephone will give priority to the person who  
speaks louder when both people are talking simultaneously. Speak ONLY after the other  
person pauses or stops.  
If the other person complains about poor transmission, talk directly at your telephone  
and from a closer distance as necessary, or lower volume control.  
If the operation of the Handsfree feature is not correct, refer to the FAILURE TO OPERATE  
section.  
19  
 
5. HEADSET OPERATION

Speed-Dialling (Storable Handsfree code)  
When storing a number, you can add a “Handsfree” command to the start of the number.  
It appears as an “H” on-screen. This programming technique makes dialling faster and  
easier – to commence dialling of anyDirectAccess memory programmed with a “Handsfree”  
code the memory key can be pressed without the need to lift the handset or press the  
Handsfree/Headset key.  
Speed-Dialling and Automatic Hang-up  
The Handsfree code may also be stored in a Direct Access memory key at the trailing  
end of a stored number to make the telephone hang up immediately after dialling the  
number.  
Example(whereHrepresentstheHandsfreecodeandnnnnnrepresentsanysubsequent  
digits to be dialled)  
1. If H is entered as a prefix code:  
Stored string: H nnnn  
Result: The phone will go on-line in Handsfree mode and dial out the subsequent  
number. Phone will remain on-line in handsfree mode until the user manually  
hangs up.  
2. If H is entered at both ends of the digits to be dialled  
Stored string: H nnnnn H  
Result: The phone will go on-line in Handsfree, dial out the number and go off line  
again.  
To store a Number and Name in a Direct Access memory  
1. Press STORE; the display will show “STORE”  
2. Press the Memory Key either once to store in a One-Touch memory or twice for a  
Two-Touch memory; the display will show “ENTER NUMBER”  
3. If you wish to setup the chosen memory key as a speed-dial key, go to step 4.  
Otherwise go to step 5  
23  
 
4. Press HANDSFREE/HEADSET; the DISPLAY will show “H” in the number field. If  
this is not required, go to step 5 without pressing HANDSFREE/HEADSET  
5. Enter the telephone number and press STORE  
6. Enter the name by using the Keypad and press STORE to confirm; the display will  
show “MEMORY STORED”.  
To dial from a Direct Access Memory  
Speed-Dial memory (i.e. the memory key has been programmed with an “H” preceding  
the number as described above):  
Press the desired Memory Key either once to dial from its One-Touch memory or twice  
to dial from its Two-Touch memory.  
Non Speed-Dial memory (i.e. the memory key has NOT been programmed with an “H”  
preceding the number as described above):  
Press the desired Memory Key either once to dial from its One-Touch memory or twice  
to dial from its Two-Touch memory.  
Direct Access Memories and the Memory Protection Switch  
The Memory Protection Switch protects the upper row of five memory keys near the  
display to prevent them from being overwritten by the user in daily use. The memory  
protect switch is located underneath the lower memory number card (see Figure 4).  
it is recommended that the upper row of 5 memory keys (i.e. 10Direct Access Memories)  
be programmed to create network features access keys to store some of your favourite  
network facility codes (e.g. Diversion, Call Forward, Call Back etc). This will enable more  
convenient access to these features without the need to remember the necessary codes.  
The memory card paper insert below the memory keys can be used to label the keys to  
indicate their new functions (i.e. the name of the network feature). Consult your system  
User Guide for the codes that you need to store.  
If your upper-row memory keys are locked and prevent storage of new numbers this may  
be due to the presence of pre-programmed codes chosen by your system administrator.  
Before moving the switch to the “Non-Protected” position we recommend that you contact  
your system administrator, Interquartz or your dealer to discuss if they can be unlocked.  
Changing the switch setting may allow any pre-programming to be lost.

DIRECTORY MEMORY  
The Directory Memory works like the memory of a typical mobile phone, with the storage  
of names with numbers and name searching capability. The keys on the Keypad allow  
the entering of alpha and numeric characters in the name field.  
If your network does not send caller name information in conjunction with the caller’s  
number, the ability of the IQ750 to display the caller’s name during an incoming call will  
be dependent on the caller’s number matching a number already stored in the Directory  
Memory. Therefore, at the time of installation it may be useful to store names and  
numbers of friends, business associates and other regular callers into theDirectory Memory  
to take immediate advantage of the name display feature. In addition, the Caller List can  
be used as a convenient source of programming data – the details of any previous incoming  
calls found in the Caller List can be stored in the Direct Access memory keys and/or the  
Directory memory by a simple transfer process, thereby reducing keystrokes and  
eliminating potential error that may otherwise result during manual storage of the same  
details. Please see the sections entitled “To store a caller’s details in a Direct Access  
Memory from the Caller List” and “To store a caller’s details in theDirectory Memory from  
the Caller List” located in the CALLER ID OPERATION section.

7. USING THE CALLER ID DISPLAY  
This section assumes that you are using the IQ750 in a network that is capable of  
supplying Caller ID data in the Bellcore GR-30-CORE format. In addition, you may need  
to request or subscribe to Caller ID and Call Waiting Services from your network provider  
before Caller ID data will be sent by the network. For details, please contact your service  
provider.  
When an incoming call is received, information including the caller’s name, number, call  
date & time will be transmitted to your Caller IDDisplay Telephone between the first and  
second rings from the network.  
Caller ID during a typical incoming call  
1. The Ringer sounds and the Ringer Indicator will flash  
2. After about 1 second, the caller’s information is shown on the display  
3. If the call is not answered, the caller’s information will be kept on the display for  
a further 10 seconds after the last ring; and the Caller Key (New Call) indicator will  
flash. The caller’s number can be up to 16 digits long, and the name can be up to 16  
characters long before exceeding the capacity of the display  
4. The details of the call will be stored in the Caller List.  
Displaying the caller’s name during an incoming call  
The caller’s name will be automatically displayed if:  
a) the name information is delivered by your telephone service in conjunction with the  
caller’s number, or  
b) if the number matches a number stored in the Direct Access or Directory Memory.  
At the time of installation it may be useful to store names and numbers of friends, business  
associates and other regular callers into the Directory Memory to take advantage of the  
name display feature.  
29  
 
In addition, the Caller List can be used as a convenient source of programming data – the  
details of any previous incoming calls found in the Caller List can be stored in the Direct  
Access memory keys and/or the Directory memory by a simple transfer process, thereby  
reducing keystrokes and eliminating potential error that may otherwise result during  
manual storage of the same details. Please see the relevant sections entitled “To store  
a caller’s details in a Direct Access Memory from the Caller List” and “To store a caller’s  
details in the Directory Memory from the Caller List”.  
CALL WAITING DISPLAY  
The IQ750 can display the details of a current caller while you are already on a call. To  
enable the Call Waiting feature, you may need to request or subscribe the Call Waiting  
Service from your network provider. For details, please call your service provider.  
Note: It is not recommended to use more than two Caller ID phones in parallel on the  
same line as their performance may be affected. For example, Caller ID display of a  
second call while you are off-hook (i.e. Call Waiting Caller ID, sometimes known as  
“Type 2 Caller ID”) may not be received by the IQ750 if another parallel connected Caller  
ID phone is in use and off hook in party line fashion on the same call.  
CALLER LIST  
The IQ750 stores the details of all incoming calls in a Caller List, which is accessible by  
pressing the Caller key. The Caller List can store up to 80 caller records, and when it has  
reached its full capacity the oldest record will be removed to accommodate the new call.  
To view the Caller List and dial a Number in the Caller List  
1. Press CALLER to display the most recent incoming call; if there is no entry in the  
Caller List, the display will show “NO ENTRIES”  
2. Press Scroll to move on to the previous call; subsequent presses will  
display successively earlier calls  
3. To dial a number displayed; press DIAL  
4. If the end of the Caller List is reached, the display will show “END OF LIST”; you  
may continue to scroll or to review the list again

8. ADVANCED NETWORK OPERATION  
Where this telephone is used on an intelligent network such as Easycall, Customnet,  
Centel, Spectrum, a PABX or any Centrex Networks, the following information may be  
useful.  
Message Waiting function in conjunction with Telstra’s Customnet, MessageBank  
and Home Messages 101 services  
The IQ750 has built-in compatibility with the above services. When the Message Waiting  
signal is received:  
1. the CALLER key will flash  
2. the display will show the words “Message Waiting” in the name field  
3. the display will show an envelope icon.  
Manually Resetting the Message Waiting Prompts  
The message waiting prompts as described above are normally controlled by the network  
to switch on and off as needed. If at any stage the telephone is found to be incorrectly  
indicating a Message Waiting condition, the erroneous indication can be cleared manually.  
To clear the MWI prompts; press CLEAR twice.  
“Talking Text” SMS Messages  
The IQ750 is compatible with the “Talking Text” SMS service. To access messages,  
please refer to the guidelines issued by your service provider.  
HOLDINGAND TRANSFERRING CALLS -This is dependent on your system type, so  
please check your system’s Extension User Guide to find out how to use the RECALL  
Key. It is sometimes known as the Flash or Facility Key.  
34  
 
PAUSE FUNCTION WHEN DIALING OUT  
Sometimes a pause is necessary either when dialling ordirnary outgoing calls,  
accessing specialised network features or perhaps when storing certain numbers in  
the memory. If you have determined that a pause is required by your host system,  
please refer to the information below. If you have already experienced dialling difficulties,  
try the suggestions below.  
AUTOMATIC TRUNK ACCESS DIGIT INSERTION  
When the telephone is used wherever a dialing prefix is required to make an external call  
(eg. normally 0 is needed for an outside line), this prefix can be stored to ensure that it is  
automatically dialled whenever an external number is dialled from the Caller List. This  
resolves a problem found in Caller ID capable network environments where the caller ID  
information delivered to the receiving telephone does not contain the outside line prefix  
necessary to complete a call-back to that caller.  
To setup, model IQ750 accepts a one or two digit Trunk Access Code as follows:  
1. Press STORE  
2. Enter the TRUNK ACCESS DIGIT (example, 0 for Customnet)  
3. Press STORE  
4. Press “ ” (STAR)  
After programming digit 0 in the above example the unit will insert a 0 in front of any  
outgoing number that is dialled from the Caller List (the list of incoming calls).  
This setting remains set until the user changes it - removal of power sources or line  
connection will not change the setting.  
AUTOMATIC PAUSE INSERTION  
The above procedure will also insert a pause after the access code before dialling the  
actual number that has been selected for call-back from the Caller List. The pause time  
can be pre-set (see below).  
35  
 
PAUSE TIME  
Sometimes the standard Pause time of 1 Second may be inappropriate, such as when a  
shorter Pause is needed to slow down a code stored in memory so that the telephone  
does not dial too quickly for the network.  
EXAMPLE: A particular network typically needs a short Pause in the Call Hold function  
code after “Recall” is sent to line and before “ 74” is dialled. A Pause time of 200mSec  
is required in that code sequence. The required Call Hold code is Recall, Pause (insert  
multiple Pause(s) here), (star),74.  
Solution: Change the Pause time from the factory default of 1 Sec to 100mSec, and then  
program the memory with enough Pauses inserted in the code to achieve the desired  
Pause time.  
FIRST change the pause time to 100mSec  
1. Press STORE; the display will show “STORE”  
2. Press  
,
, STORE; the display will show “1-RECALL 2-PAUSE”  
3. Press 2 to enter Pause Time Selection; the display will show “PAUSE 1 SEC”  
(the factory default Pause time)  
4. Press Scroll (the one above the DIAL key) Up or Down to select 100mS  
5. Press STORE to confirm selection; the display will show “PAUSE STORED”.  
THEN program the Call Hold function code with 200mSec of Pause time (two  
100mSec Pauses) as follows:  
1. Press STORE; display shows “STORE”  
2. Press any memory key; the display shows “ENTER NUMBER”  
3. Press RECALL, PAUSE (twice),  
, 74; the display shows “FPP 74”  
4. Press STORE; the display shows “ENTER NAME”  
5. Enter text “CALL HOLD” on the keypad  
6. Press “STORE”; the display shows “MEMORY STORED”  
7. Test for resulting Pause time stored in that memory key for network compatibility by  
pressing that memory key at the appropriate time and observing the result.  
36  
 
If two Pauses (i.e. 200 mSec) do not produce a long enough post-Recall pause for the  
network switch, try three pauses (300mSec) or four (400mSec) or more.  
The Pause time setting remains set until the user changes it - removal of power sources  
or line connection will not change the setting.  
HOLDING AND TRANSFERRING CALLS  
The method used for these functions is dependent on your system type, so you will need  
to check your system’s Extension User Guide. The RECALL Key is typically used to  
transfer calls and the Recall Timing setting affects the Recall Key’s ability to function  
correctly with your system (see below).  
USING THE MEMORIES  
Any combination of numbers,  
and  
, Pause, Recall and Handsfree commands can  
be stored. You may find it useful to store some of your favourite network facility commands  
in the telephone for fast, convenient access to those facilities (e.g.Diversion, Call Forward,  
Call Back etc). Consult your system User Guide for the codes that you need to store.  
TheDirectAccess Memories can be pre-programmed at point of sale with network feature  
codes. For further information, please refer to the “Memory Operation” and “Memory  
Protection Switch” sections of this manual.  
Speed Dialing  
When storing a number, you can add a “Speed Dialing” command to the start of the  
number. This makes dialling faster and easier. The “H” command, entered by pressing  
the HANDSFREE/HEADSET preceding the telephone number in the Memory Storage  
procedure, activates the Handsfree function during dialing so that you can make a Handsfree  
call just by pressing the memory key once it is programmed.  
Cascade Memory Dialing  
The contents of more than one memory can be “cascaded” or added together during a  
call to create a long dialling sequence by pressing the required memory keys in the  
desired order. This feature can be used to store unusually long numbers, which may  
exceed the digit capacity of any individual memory.

light does not function correctly, your IQ750 may need an optional circuit to be added to  
make it compatible with your system. If you have a Centrex system (eg. Spectrum) the  
Caller key indicator and the “Mail” (envelope) icon will flash and “MESSAGE WAITING”  
will be displayed. To retrieve your message, consult your voice mail system user guide.  
HEADSET MIC ADJUST CONTROL  
This control allows many different headsets on theAustralian market to function correctly  
with the IQ750 telephone by adjusting the Headset Microphone sensitivity. The control is  
located on the underside of the telephone (see Figure 8). The adjustment can be made  
by a small screwdriver or similar implement that will fit into the control slot. Please see  
Table 1 as a guide to the correct settings for some popular Headsets.  
41  
 
TO MAKE A HEADSET MIC LEVEL ADJUSTMENT  
With the Headset connected as per the instructions in this manual:  
1. Put the Headset on and lift the Handset to your other ear and make an outgoing call  
2. Pressing the HANDSFREE/HEADSET Key, swap between Handset and Headset  
modes (the indicator will illuminate when the Headset is in use). Do this a few  
times while speaking to the other party by repeatedly pressing the HANDSFREE/  
HEADSET Key while holding a conversation  
3. Use the other party’s help to decide if your voice level is the same on the Headset in  
comparison to the Handset

clockwise) so that your voice level when using the Headset matches that of the  
Handset. Clockwise rotation increases the Headset Mic output level. Please see  
Table 1 as a guide to the correct settings for some popular Headsets.

10. GENERAL CARE AND MAINTENANCE  
This telephone is a precision electronic instrument. While in use and storage, care should  
be taken to avoid rough handling, extreme temperature, and damp or dirty environments.  
CLEANING  
NEVER use aerosol sprays or other chemical agents or substances that leave a residue  
(furniture polish for example).  
Use a mild detergent and a damp, clean cloth when cleaning. Do not allow moisture to  
enter the telephone interior - damage may result!  
FAILURE TO OPERATE AND SERVICE DIFFICULTIES  
If telephone service problems occur at any time, it is recommended that the installation  
procedure described in this manual be re-checked.  
If a fault occurs, try to determine if the fault is with the telephone, or with the network or  
system to which the telephone is connected:  
Disconnect the “suspect” telephone, and test the line with a substitute telephone. If the  
telephone service then operates satisfactorily, the fault is in the “suspect” telephone.  
Test the “suspect” telephone on a known good line. If the fault still occurs, the fault is in  
the “suspect” telephone.  
Consult your Interquartz dealer for further advice if necessary.

11. THUNDERSTORMS  
The telephone, in common with household electrical appliances, can be a source of  
electric and acoustic shock during thunderstorms. The possibility of a telephone user  
experiencing a shock is minimal. Nevertheless, customers should be aware of some  
simple precautions to follow during thunderstorms:  
Use your telephone only for calls of the utmost urgency. Keep these calls brief. Whilst  
using your telephone keep clear of electrical appliances and metal fixtures such as :  
stoves, air conditioners, refrigerators, window frames and sinks.
