This equipment has been tested and found to comply with
the limits for a Class B digital device, pursuant to Part 15 of
FCC Rules
the
reasonable protection against harmful interference in a
residential inst al lat ion . T his equipment generates, us es a nd
can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause
harmful interference to radio communications.
However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference
by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and
receiver.

You must use a Class
2 power source that
!
supplies regulated 9V
DC and delivers at least 400
mA. Its center tip must be set to
positive and its plug must fit the
intercom's DC 9V jack. Using an
adapter that does not meet
these specifications could
damage the intercoms or the
adapter.
• 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
month or more, remove the
batteries. Batteries can leak
chemicals that can destroy
electronic parts.
• Always connect the AC adapters
to the intercoms before you
connect them to AC power.
When you finish, disconnect the
adapters from AC power before
you disconnect them from the
intercoms.

• Consult your local Rad ioShack store or an ex perienced
radio/TV technician for help.
• If you cannot eliminate the interference, the FCC
requires that you stop using your intercoms.

You can power your intercoms using four AA alkaline or
rechargeable nickel-cadmium (Ni-Cd)/nickel-metal hydride
(Ni-MH) batteries (not supplied). For the best performance
and longest life, we recommend RadioShack batteries.

Once each intercom has been turned on and you connect

rechargeable batteries (if installed) are automatically
charged while the intercom is transmitting and standing by.
The battery life for recharg eable batterie s (Ni-MH, 15 00mA)

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 t ime varies, depending on capacity. Typically, NiMH (1500 mA/H) batteries charge in about 12 hours. Ni-Cd
(700 mA/H) batteries charge in about 4 hours.

The intercoms use radio frequencies called
communicate with each other. Your intercoms have four
channels. The intercoms also use
sub-tones
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:

the nickel-cadmium
(Ni-Cd) battery indicates
RadioShack is voluntarily
participating in an industry
program to collect and recycle
these batteries at the end of their
useful life, when taken out of
service in the United States or
Canada. The RBRC program
provides a convenient alternative
to placing used Ni-Cd batteries
into the trash or the municipal
waste stream, which may be illegal
in your area. Please call 1-800THE-SHACK (1-800-843-7422) for
information on Ni-Cd battery
recycling and disposal bans/
restrictions in your area.
RadioShack’s involvement in this
program is part of the company’s
commitment to preserving our
environment and conserving our
natural resources.

Preparation
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.
