Operating Procedure 

 

The GWD915/910 is designed to eliminate unnecessary hassle of pairing a receiver with a 
particular wireless microphone.   With the latest technologies, the GWD915/910 is able to 
synchronize the frequency of any GWD915T/910T Wireless Microphone with any 
GWD915R/910R Receiver.   

 

Just follow these few simple instructions to ensure maximum performance:  

 

1. 

Check out any GWD910T Wireless Microphone and make sure it is fully charged 
before operation.   

 

2. 

Please be sure the  IN-CAR VIDEO SYSTEM  is ON before proceeds any further.  

 

3. 

Slide the wireless microphone 
contact directly on top of the 
receiver’s register contact (

located on 

the top of the IN-CAR VIDEO 
SYSTEM monitor module

) until a 

confirmation tone has sound.  This 
indicates the receiver’s register 
contact has synchronized the 
frequency of the receiver and the 
wireless microphone.   Wireless 
microphone is now on standby mode 
and is ready for use.    

 

4. 

Please only synchronize one wireless microphone to one receiver. 

 

5. 

There are three methods to activate recording on the wireless microphone: 

 

a. 

Press the ON or Panic Button once on the wireless microphone for 
recording. 

 

b. 

Activate video recording at the  IN-CAR VIDEO SYSTEM.  This action 
will automatically trigger wireless microphone recording. 

 

c. 

Turn on the light bar or siren in the patrol car.  This action will also 
automatically trigger wireless microphone and video recording. 

 

6. 

To prevent accidental audio shut off.  The only way to return wireless 
microphone to standby mode from recording mode is to stop the video recording 
from the  IN-CAR VIDEO SYSTEM.  

Or press and hold PB2 until 3Seconds

.

 

 

7. 

During recording mode, if the warning sounds and the yellow LED flash, this 
means the signal is marginal or weak.  At this time, please step closer to the 
receiver or reposition the wireless microphone until the warning stops.  However, 
if the warning persists and exceeds 30 seconds, the wireless microphone will 
automatically shut off and return to standby mode. If user returns within the 
signal range again while the video is still recording, the receiver will re-initiate the 
wireless microphone automatically. 

8. 

For charging, simply place the wireless microphone to the charger and leave it 
charging for at lease 6 (six) to maximize battery capacity.
