Communication Address Setup 

A RF transmitter controls one 8294-07 monitor.  The transmitter is digitally encoded with a security 
code to ensure that it does not accidentally control the wrong monitor.  The receiver has a matching 
decoder and security code that instantaneously decodes and interprets commands.  The security code 
is a 15-bit selectable code that is set on both the remote transmitter and the receiver.   

 

The  8294-07  monitors  are  tested  and  shipped  with  a  security  code  based  upon  the  monitor  serial 
number, ensuring each  monitor leaves the factory with a unique code assigned to it.  The security 
settings will normally not need to be changed.  In the case of a lost transmitter or replaced control 
board, use the following instructions to change the security settings.   

 

 

Danger:     

Using  two  W.E.T.  monitors  with  the  same,  security  code  may  cause  the 

inadvertent  control  of  the  wrong  monitor,  resulting  in  possible  property  damage  and  injury  to 
personnel.  Using the factory specified codes will prevent this problem.   

 

 

Caution:

  Do not pinch wires when attaching back panel to front panel of the handheld 

enclosure.  Ensure all O-ring and gaskets are properly installed when closing receiver or transmitter 
enclosures.

Caution:  

The RF Receiver/Control Module and all transmitters’ communication addresses 

have been set at the factory.  They should not require any additional address settings.
