1. Insert each AC adapter’s barrel plug into
DC 9V
on the
top of each intercom.
2. Plug the other end of the adapters into a standard AC
outlet.
Complete charging takes about 10 to 12 hours. Average
charging time varies, depending on capacity. Typically, Ni-
MH (1500 mA/H) batteries charge in about 12 hours. Ni-Cd
(700 mA/H) batteries charge in about 4 hours.
When charging is complete, unplug the AC adapter from the
power source, then disconnect it from
DC 9V

The intercoms use radio frequencies called
channels
to
communicate with each other. Your intercoms have four
channels. The intercoms also use
sub-tones
within the
channels to help eliminate interference between intercoms,
even if someone is using another intercom set to the same
channel. Your intercoms have eight sub-tones.
The channels and sub-tones let you set each intercom so
they can:
• communicate with each other
• communicate with additional intercoms you purchase.
•
not
communicate with other intercoms
For example, if you have more than two intercoms installed
in your home, you can set them so the intercom you
installed at the front door communicates only with the
intercom you installed in the kitchen (so guests at the door
can announce themselves to somebody working in the
kitchen).
You must set any two intercoms to the same channel and
sub-tone for them to communicate with each other.

Each intercom has a group of DIP switches inside the
battery compartment. Use an object such as a straightened
paper clip to set the DIP switches.
1. On each intercom, slide the battery compartment cover
on the back of the intercom in the direction of the arrow
to remove it.
