By default your two intercoms are on the same 

channel, but you can change your intercom channels 

for your system. Or, if you receive interference on a 

channel you selected, set each intercom to one of eight 

different sub tones. Complete the following to change 

the intercoms channel or sub tone:
1.  Open the battery compartment of the intercom and 

set the 

SUB

 or 

CH

 switches. 

2.  Use a pointed object to set the first three switches 

(labeled 

SUB TONE

) inside the battery compartment 

you want to use.
