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.

Battery Notes:
• Use only fresh batteries of the required size and
recommended type.
• Do not mix old and new batteries, different types
of batteries (standard, alkaline, or rechargeable), or
rechargeable batteries of different capacities.
• If you do not plan to use the intercoms with
batteries for a week or more, remove the batteries.
Batteries can leak chemicals that can destroy
electronic parts.
• Dispose of old batteries promptly and properly. Do
not burn or bury them.
• Always connect the AC adapters to the intercoms
before connecting them to AC power.
• Do not attempt to charge alkaline batteries and
never install non-rechargeable batteries when
RECHARGE ON/OFF is set to ON. Nonrechargeable
batteries can get hot or explode if you try to charge
them.
To charge rechargeable batteries (not included), slide
the RECHARGE ON/OFF switch to ON, install batteries,
plug in the AC adapter, then turn on the intercom.
Complete charging takes about 12 to 14 hours. Average
charging time varies with different battery capacity.
