FEATURES
Your RadioShack Two-Station Wired Intercom System is ideal for home, office, and shop applications.
It is also convenient for monitoring activities in another part of the house, such as a baby’s room.
The system includes one master station and one remote station, with a 66-foot (20m) interconnection
cable and staples for fastening the cable to a wall,
floor, or baseboard.
Your system’s features include:
Master Station Volume Control — lets you adjust
the volume of the master station for different listening situations.
Wall-Mounting Option — lets you save desk space
by wall-mounting both intercom stations.
Station Monitoring — you can use the master station to monitor sounds at the remote station.

INSTALLATION
INSTALLING A BATTERY
Your intercom system uses one 9-volt battery for
power. For the best performance and longest life,
we recommend an alkaline battery, such as RadioShack Cat. No. 23-553.
Caution: Use only a fresh battery of the required
size and recommended type.
1. With the master station (the unit with the volume control) face up, open its case by inserting
a coin into the slot between the top and bottom
of the case and twisting the coin. Lift off the top
case and lay it face down on a flat surface.

43-222b.fm Page 5 Thursday, August 12, 1999 3:55 PM
2. Snap the battery connector over the 9V battery’s terminals.
3. Put the battery inside the case on top of the
foam cushioning material.
4. Snap the case halves together.
Cautions:
• Always remove old or weak batteries. Batteries
can leak chemicals that can destroy electronic
parts.
• Dispose of an old battery promptly and properly. Do not burn or bury it.

CONNECTING THE STATIONS
Choose the most convenient locations for the master and remote stations. You can place them on a
desk or shelf, or mount them on a wall.
Plug the connector on one end of the supplied 66foot-long cable into the remote station’s jack. Plug
the connector on the other end of the cable into the
master station’s jack.

43-222b.fm Page 7 Thursday, August 12, 1999 3:55 PM
Notes:
• Be sure to route the cable so it will not be
pinched by doors or stepped on.
Use the supplied mounting staples to hole the
cable in place. Simply position the cable
between the prongs of each staple you need,
then gently tap the staple with a hammer until
the staple’s gray coating touches the wall.
• To install the stations farther than 66 feet apart,
you can make a connecting cable of 22 gauge
wire (Cat. No. 278-862) and two 1/8-inch twoconductor plugs (Cat. No. 274-288).

Wall Mounting
For wall mounting, you need two flat-head screws
(not supplied) with heads that fit into the keyhole
slots on the bottom of the base.
Drill two holes 25/8 inches (67 mm)
apart. Then thread a screw into
each hole, letting the heads extend about 5/32 inch (4 mm) from
the wall.
Align the keyhole slots with the
mounting screws and slide the station downward to secure it.
