Changing the system channel code

NOTE:

more systems are in close proximity, system codes can be used to avoid interference from 
other SA3000 systems using up to a maximum of 16 channels.

The monitor is supplied with no 

system code switches set (system code 1). 

For reference this is the factory setting 

should you need to re-set the unit.

System codes can be set using 

key switches 1 - 4. 

The diagram to the right shows the 16 

possible combinations.

Be sure that the same system code is set on 

the receiver to be used and any other 

monitoring options in that system.
