ABOUT WWVB (Radio Controlled Time)
The NIST (National Institute of Standards and Technology—Time and Frequency
Division) WWVB radio station is located in Ft. Collins, Colorado, and transmits the exact
time signal continuously throughout the United States at 60 kHz. The signal can be
received up to 2, 000 miles away through the internal antenna in the projection alarm.
However, due to the nature of the Earth’s Ionosphere, reception is very limited during
daylight hours. The projection alarm will search for a signal every night when reception
is best. The WWVB radio station derives its signal from the NIST Atomic clock in
Boulder, Colorado. A team of atomic physicists is continually measuring every second,
of every day, to an accuracy of ten billionths of a second per day. These physicists have
created an international standard, measuring a second as 9,192,631,770 vibrations of a
Cesium-133 atom in a vacuum. For more information about WWVB please see the NIST
QUICK SET-UP GUIDE
Hint: Use good quality Alkaline Batteries and avoid rechargeable batteries.
1. Have the indoor station and outdoor remote 3 to 5 apart.
2. Batteries should be out of both units for 10 minutes.
3. Place the batteries into the outdoor remote first then into the indoor station.
(All outdoor remotes must be started before the indoor station)
4. DO NOT PRESS ANY BUTTONS FOR 10 MINUTES.
In this time the display and sensor will start to talk to each other and the display will
show both the indoor temperature and an outdoor temperature. If the station does not
display both temperatures after the 10 minutes please retry the set up as stated above.
After both indoor and outdoor temperatures are displayed for 10 minutes you can place
your sensor outdoors and set your time.
The remote sensor should be placed in a dry, shaded area. The remote sensor has a range
of 80 feet. Any walls that the signal will have to pass through will reduce distance. An
outdoor wall or window will have 20 to 30 feet of resistance and an interior wall will
have 10 to 20 feet of resistance. Your distance plus resistance should not exceed 80 ft. in
a straight line.

NOTE: Fog and mist will not harm your remote sensor but direct rain must be avoided.
To complete the set up of your temperature station after the 10 minutes have passed
please follow the steps starting on page 6.
DETAILED SET-UP GUIDE
Important: Insert batteries into the transmitter first, then into the alarm clock. Do
not press any buttons until remote temperature is displayed.

3. The batteries will fit tightly to avoid start-up
problems make sure that they do not spring free
during installation.
4. Replace the battery cover.
B. Projection Alarm
1. Remove the battery cover.
2. Observe the correct polarity,
and install 3 AA batteries.
3. In addition to, or instead of
inserting batteries, the AC
adapter can be used. Simply
insert the adapter into the
receptacle on the underneath
of the alarm clock and then plug the adapter into the wall socket.
4. Replace the battery cover.
The projector will activate and remain on if the alarm clock is plugged in. If
only batteries are used, the projector will only be activated when a button is
pressed. The projection is a red light, not harmful under normal usage, although
care should be taken to not look directly into the light.
Note: After the batteries have been installed a tone will sound, and the LCD
(Liquid Crystal Display) will activate. The indoor temperature and the remote
temperature will be displayed (within three minutes). Also, the time will appear
as “-:--”. The WWVB search is automatically initiated, and a tower icon
appears and flashes with the time colon (no tower icon will appear if the WWVB
is too weak to be detected, and the time display will remain on “-:--”). While
4
the WWVB search is being conducted various numbers will appear in the time
display. After 10 minutes, the projection alarm will either display the WWVB
time or discontinue the search if the time is not found. If the search is cancelled
“-:--” will remain in the time LCD. The projection alarm will conduct a WWVB
search every hour until the first signal is found. Once the WWVB time is found,
a search is automatically conducted nightly at midnight. If the signal is found at
midnight the tower icon will remain. If the signal is not found another search
will take place every hour, until 6:00 am, until the signal is found successfully.
If no signal is found during this period the tower icon will not appear and the
clock will search again at 12:00 am the next night.

B. Radio-Controlled Time and Date
1. The projection alarm will automatically search for the time signal upon
initial set-up and every night.
2. When the signal is being received, there will be a “tower” icon flashing to
the left of the time display.
3. When the time signal has been received successfully, the tower icon will
remain steady until midnight.
4. The NIST (National Institute of Standards and Technology—Time and
Frequency Division) WWVB radio station is located in Ft. Collins,
Colorado, and transmits the exact time signal continuously throughout the
United States at 60 kHz. The signal can be received up to 2,000 miles away
through the internal antenna in the projection alarm.
5. Due to the nature of the Earth’s Ionosphere, reception is very limited during
daylight hours. The projection alarm will search for a signal every night
when reception is best.
6. The WWVB radio station receives the time data from the NIST Atomic
clock in Boulder, Colorado. A team of atomic physicists is continually
measuring every second, of every day, to an accuracy of ten billionths of a
second per day. These physicists have created an international standard,
measuring a second as 9,192,631,770 vibrations of a Cesium-133 atom in a
vacuum.
the NIST time, call (303) 499-7111. This number will connect you to an
automated time, announced at the top of the minute in “Coordinated
Universal Time”, which is also known as Greenwich Mean Time (GMT).
This time does not follow Daylight Saving Time changes. After the top of
the minute, a tone will sound for every second.
8. It is possible that your projection alarm may not be exactly on the second
due to the variance in the quartz. However, the clock will adjust the quartz
timing over the course of several days to be very accurate; under 0.10
seconds per day.
Projection of Time and/or Remote Temperature
When plugged into an AC outlet the projection alarm can continuously
project the time and/or remote temperature.
9. When operating on batteries alone the projection alarm will only project
when a button is pressed.
10. The projection will auto-focus for display from three to six feet away. A
dark surrounding will be necessary to clearly see the projection.
11. The default is projecting time (Hour and Minutes). The projection alarm
can be se to project the time (M0), remote temperature (M1), or alternating
8
between time and remote temperature (M2) by pressing the “DISPL”
button. The selected display mode will flash on the lower left as “M0”,
“M1” or “M2”.
12. The direction of the display can also be rotated 360° in 90° increments by
pressing the directional button. There is no display on the LCD that
signifies the direction.
13. The projector case can be rotated 180° to further help orient the projected
display.
14. The intensity of the projection can be adjusted to three different settings as
well as turned “off” by pressing the light Intensity button. When turned off,
the projection will only come on when a button is pressed. The intensity
cannot be set for the projected display when set to “off”. When only
batteries are used, the intensity setting is set to “off” with no other options.

C. Forecast Icon
1. The weather forecasting feature is estimated to be 75% accurate. The
weather forecast is based solely upon the change of air pressure over time
2. The WT-5432 averages past air-pressure readings to provide an accurate
forecast—creating a necessity to disregard all weather forecasting for 12-24
hours after the unit has been set-up, reset, or moved from one altitude to
another (i.e. from one floor of a building to another floor). In areas where
the weather is not affected by the change of air pressure, this feature will be
less accurate.
3. Weather Icons
There are 3 possible weather icons that will be displayed in the FORECAST
LCD:
Sunny—indicates that the weather is expected to improve (not that the
weather will be sunny).
Sun with Clouds—indicates that the weather is expected to be fair (not
that the weather will be sunny with clouds).
9
Clouds with Rain—indicates that the weather is expected to get worse
(not that the weather will be rainy).
The weather icons change when the unit detects a change in air
pressure. The icons change in order, from “sunny” to “partly sunny” to
“cloudy” or the reverse. It will not change from “sunny” directly to
“rainy”, although it is possible for the change to occur quickly. If the
symbols do not change then the weather has not changed, or the change
has been slow and gradual.
D. EL Backlight
1. The projection alarm has an EL backlight designed for night viewing. This
will light up for 2 seconds whenever a button is pressed.
2. The EL backlight cannot be turned on constantly as this would drain the
batteries and burn out the EL light.
E. Indoor Temperature
1. The projection alarm measures indoor temperature with an internal sensor.
2. This temperature is displayed in °F or °C depending on the time format (12
or 24 hour mode). When in 12-hour format, the temperature will be in °F.
When in 24-hour mode the temperature will be in °C.
3. The indoor temperature will take time to adjust to the surrounding
temperature as the sensor is inside the case.
4. If the remote temperature is placed next to the projection alarm more often
than not the temperature will not be exact with one another. This is not a
defect, but simply reflects the difference in measuring methods. The remote
temperature is designed for changing temperature at a wide range.
F. Remote Temperature
1. The projection alarm comes with a remote temperature sensor. When set up
properly the projection alarm will receive and display the remote
temperature.
2. It is important to power up the transmitter first then the projection alarm. If
batteries are removed in the remote temperature sensor the projection alarm
MUST be re-set by removing power sources and re-starting.
3. The remote temperature is measured within the remote temperature sensor
and transmitted to the projection alarm. If outdoor temperature is desired
simply mount the remote temperature sensor outside. It is recommended to
mount the remote temperature sensor on the North side of the house away
from sources of heat or cold (away from direct sunlight, windows, vents,
etc.)
4. The range of the transmitter is 80 feet in open space. While the signal is
able to penetrate walls it will decrease the range. Concrete and metal
structures offer the most resistance.
10
5. The transmitter should not be mounted on a metal surface.
6. The transmitter and projection alarm should be kept away from other
sources of possible interference including cordless appliances (telephones,
baby monitors), microwave ovens, and other strong electrical appliances.
7. The remote temperature is displayed in °F or °C, depending on the time
format (12 or 24-hour mode). When in 12-hour format, the temperature
will be in °F. When in 24-hour mode, the temperature will be in °C.
G. Time Alarm
The projection alarm has two separate alarms for time, “ALM1” and “ALM2”.
The alarms have a different sound; “ALM1” increases in volume after 25
seconds, and again after 50 seconds. “ALM2” is a constant volume. The total
duration is 96 seconds for each alarm.
1. Setting the Alarm
a. Press and hold “ALM1” or
Alarm 2 activated
“ALM2” for two seconds until the
alarm time is flashing.
b. Press and release “ALM1/HOUR”
to advance the hour and
“ALM2/MIN” to advance the
minute. The time will display “PM”
if set to PM and nothing if set to
AM.
c. The projection alarm will revert to
normal operation when no buttons
are pressed for 15 seconds.
2. Activating/Deactivating the Alarm
a. After entering the alarm-setting mode the alarm is activated (either
ALM1 or ALM2).
b. To toggle between activating and deactivating the alarm press either the
“ALM1” or “ALM2” buttons briefly. “(((1)))” or “(((2)))” will be
displayed to the right of the time display when the alarm is activated.
c. When the snooze bar is pressed the display will scroll through the
alarm 1 and alarm 2 times in the lower left.
3. Turning the Alarm Off (While Sounding)
a. While either alarm is sounding press and release the “SNOOZE” bar to
disable the alarm for the set duration (See Section II. D.). If the
duration is set to “0” the alarm will be disabled for 24 hours.
b. After the “SNOOZE” bar is pressed the lower left will display the time
remaining on the snooze. The “SNOOZE” bar may be pressed at any
time to restart the snooze duration.
11
c. To disable the alarm for 24 hours press and release any button other
than the “SNOOZE” bar or projection keys.
H. Changing the Display Mode (Day, Seconds and Temperature)
There are six possible display modes to view the day, seconds and temperature
(remote temperature is constantly displayed). To change the display (starting at
the default of day, month, date, remote temperature):
1. Press and release the “MODE/+” button. The display will now show
month, day, year, remote temperature
2. Press and release the “MODE/+” button again and the display will now
show seconds, remote temperature
3. Press and release the “MODE/+” button again and the display will now
show alarm1 time/remote temperature
4. Press and release the “MODE/+” button again and the display will now
show alarm2 time, remote temperature
5. Press and release the “MODE/+” button again and the display will now

1) with the use of screws
2) using the adhesive tape
A. Mounting with Screws
1. Remove the mounting bracket from the remote temperature sensor. The
bracket should snap off easily.
2. Place the mounting bracket over the desired location.
3. Through the three screw holes of the bracket mark the mounting surface
with a pencil.
4. Where marked, start the screw holes into the mounting surface.
5. Screw mounting bracket onto the mounting surface. Ensure that the screws
are flush with the bracket.
6. Snap the remote temperature sensor onto the mounted bracket.
B. Mounting with Adhesive Tape
1. With a nonabrasive solution, clean and dry the back of the mounting bracket
and the mounting surface to ensure a secure hold. The mounting surface
should be smooth and flat.
2. Remove the protective strip from one side of the tape.
12
3. Adhere the tape to the designated area on the back of the mounting bracket.
4. Remove the protective strip from the other side of the tape.
5. Position the remote temperature sensor in the desired location, ensuring that
the projection alarm can receive the signal.
V. Maintenance and Care
A. Extreme temperatures, vibrations, and shock should be avoided to prevent
damage to the units.
B. Clean displays and units with a soft, damp cloth. Do not use solvents or
scouring agents—they may mark and damage the displays and casings.
C. Do not submerge in water.
D. Immediately remove all low powered batteries to avoid leakage and damage.
E. Replace with new batteries only, and of recommended size.
F. Opening the casings invalidates the warranty. Do not try to repair the units.
