If poor or no operation is observed, ensure the external DC voltage supply is b9  
and +16 Vdc with correct polarity.  All AMP Transmitters have over-voltage and reverse 
polarity protection circuits.  If the input voltage is over +16 Vdc, remove the DC Power 
Cable from the transmitter, reduce the DC voltage to b9 and +16 Vdc, and 
reconnect the DC Power Cable.  If the input voltage is negative polarity, remove the DC 
Power Cable from the transmitter, reverse the connections between the DC voltage 
supply and DC Power Cable, and reconnect the DC Power Cable. 

 

If all connections are adequate, switches are correctly configured, and DC voltage is 
correctly applied, check the video camera, video cable, and antenna for damage.  A 
monitor may be connected directly to the camera to verify proper camera operation.  If 
receiving video but no audio, check connections between microphone and Audio Cable.  
Also check microphone and Audio Cable for damage. 

 

If these efforts fail, 

do not attempt to repair the unit.  

Please contact Dyplex or AMP 

with a detailed description of the problem.  Depending on the nature of the problem, 
Dyplex or AMP may provide further troubleshooting assistance or advise the entire 
system be returned for repair and retest. 

 

Caution: Removal of the cover constitutes breaking the seal and VOIDS PRODUCT 
WARRANTY.  

 

5.3 Preparation 

for 

Reshipment 

If the transmitter and/or any other purchased item(s) are to be shipped to another location 
or returned for repair or realignment, use the original packaging or a sturdy box with 
sufficient protective material to avoid damage from movement or exposure during transit.  
Remove all external connections (cables, antenna, etc.) prior to shipping.
