mounting the intercom
• Be sure you install the intercoms at least 10 feet away from each other. Or, you may hear a squeal from
the speakers.
NOTES
• The intercoms can transmit up to 200 feet line of sight.
1. Align horizontally
to position and
drill two holes
smaller than the
screws.
2. Thread a anchor
and screw (not
supplied) into
each hole.
connecting an audio source
To transmit audio to each intercom, connect AUX
INPUT of a intercom to an audio source's output jack
(such as AUX OUT or TAPE OUT) through an audio
cable (not supplied). Follow the instructions in the
owner's manual for your audio equipment to play
audio.
• If you use the AUX broadcasting feature
and also use the weather radio inputs, you
MUST connect the Weather radio alarm's
output to the unit that is using the AUX
broadcasting feature. The weather radio
inputs must not be connected to a unit that
is RECEIVING the broadcast.
NOTES
• Always connect the weather radio's alarm
output to the intercom you frequently use to
broadcast.
• If your audio sources cable does not have
the appropriate connector to attach to the
intercom, use an adapter available at your
RadioShack store or at RadioShack.com.
listening to an audio source
• Each intercom can broadcast from a connected
audio source only when the channel to which it is
set to is not being used to transmit voice from one
intercom to another.
• You can only broadcast from one intercom at a
time.
• Adjusting VOLUME on the intercoms does not
change the intercom's input sensitivity.

3. Align the
intercom's keyhole
slots with the
mounting screws
and slide the
intercom down
onto it to secure.
4. Lift and rotate the
antenna up so it
stands vertically.

WX INPUT
AC Adapter plug
NOTES
The AUX INPUT for audio source is disabled when VOX mode is activated.
connecting a weather radio
To transmit weather alerts to each intercom, connect the WX INPUT of a intercom to your weather radio's ALERT
OUT terminals. Follow the instructions in the owner's manual for your weather radio to create a weather alert.
• If you connect an intercom to both a weather radio and an audio source and both sources are playing at the
same time, the intercom always sounds the weather alert first.
• The intercom's weather alarm will only shut off after the weather radio alerts expire or after you manually stop
the weather radio alert. To avoid disturbing neighbors/pets if you are away from the weather radio, turn off the
intercom or lower the volume before leaving.
• To stop the alert from a weather radio, it is recommended to manually reset the ALERT OUT terminal of the
weather radio. For example on the RadioShack 12-262 weather radio, you must press the WEATHER/SNOOZE
button twice during an alert to reset ALERT OUT (refer to the User's Guide for your specific weather radio
model).
• The RadioShack Cat. No.12-262 weather radio (not supplied) has alert output terminals you can use to connect to
the intercoms.

RF Emissions Information
This equipment has been tested and found to comply with the limits for a Class
B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed
to provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses, and 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

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.
• Connect the equipment into an outlet on a circuit different from that to which
the receiver is connected.
Consult your local RadioShack store or an experienced radio/TV technician for help.
If you cannot eliminate the interference, the FCC requires that you stop using your
intercom. Changes or modifications not expressly approved by RadioShack may
cause interference and void the user's authority to operate the equipment.
Only use the antenna attached to this product. This device complies with Part 15
of the FCC Rules. Operation is subject to the following two conditions: (1) This
