2 Set the channel and sub tone
To change channel and sub tone
settings, use a pointed object to set
the SUB TONE and CH switches
inside the battery compartment.
Your intercoms have four channels
to set the radio frequencies used to
communicate with each other. They
also have eight sub tone settings to
help eliminate interference.
Your intercoms must be set to the
same channel and sub tone for them
to communicate with each other.
1. Set each intercom to channel 1,
2, 3, or 4 as shown.
2. Set each intercom to sub tone
1–8 as shown.
n Notes:
•
If you want all the intercoms
to communicate with each
other, set them to the same
channel and sub tone.
