clockwise.  
Battery replacement  
• A brand-new battery will provide the power enough to operate the unit  
continuously for 10 hours.  
Orange LED  
Indicates the battery  
level by lighting or  
flashing.  
• As long as the battery has sufficient power for the microphone to function  
properly, the orange LED will light. When the orange LED starts to fade and  
then flash, replace it with a new one.  
7. OPERATION  
Step 1. Make sure that the receiver and the wireless microphone are of the same channel (frequency).  
Step 2. If they are not identical in channel, you have to adjust the channel switch.  
Step 3. Place the microphone ON/OFF switch in the ON position.  
The orange LED indicates the circuit is active.  
Step 4. Make sure to shift the ON/OFF switch back to the OFF position after using the wireless microphone.  
8. OPERATIONAL HINTS  
• The microphone's service distance is 3 – 120 m. When the microphone user moves in a facility, signal  
dropouts (momentary losses of signal reception) may be encountered. These dropouts are caused by the  
building's architectural designs or materials which block the travel of or reflect the radio signal. If this occurs,  
the user needs to change locations for better signal reception.  
• The proper operation of your wireless system may be interfered with by other system operating on the same  
frequency. In such cases, change the operating frequency of your system. (As to dealing with the  
interference, refer to the operating instructions of the wireless tuner.)  
• Should you have any questions regarding the use or availability of TOA wireless products, please contact  
your local TOA dealer.  
9. CHANNEL NUMBER SETTING  
Step 1. Switch off the power. Rotate the microphone grip  
counterclockwise to remove it.  
Step 2. Using the supplied screwdriver, set the Channel setting  
switch pointer to the desired channel number.  
Step 3. Replace the microphone grip.  
Note: Make sure that the wireless microphone is identical to  
the wireless tuner in the channel number. Should the  
microphone's setting differ from that of the tuner, the  
tuner does not receive the microphone signal.
