Follow these steps to prepare the stations for use.

1.  To turn on the station, rotate VOLUME clockwise until it clicks.  The
    power indicator lights.  Set VOLUME to mid-range.

2.  Set CHANNEL for each station to the appropriate channel, as follows:

    If you want all the stations to communicate with each other at the
    same time, set all stations to the same channel.

    If you want to set up separate communication systems, set each station
    to a different channel.

    For example, at home  you set the kitchen's station to Channel A, the
    family room's station to Channel B, and the bedroom's station to
    Channel C.  The kitchen can communicate with the family room by
    setting CHANNEL to B and with the bedroom by setting CHANNEL to C.

CALLING

Follow these steps to talk to another station.

1.  Slide CHANNEL to the channel (A, B, or C) of the station you are
    calling.

2.  Press CALL.  The talk indicator lights.  Each station set to the
    selected channel sounds a tone.

3.  Press and hold down TALK.  The talk indicator lights.  Speak in a
    normal voice.  Then, release TALK when you finish speaking and listen
    for the response.

Notes:  The talk indicator remains lit as long as you are in the talk
        mode.  It goes out when you release TALK.

        If your voice sounds distorted, you might be speaking too loudly
        or too close to the microphone.

LISTENING

When you hear a call tone or a caller's voice, adjust VOLUME to a
comfortable listening level.

Note:  Only one party can speak on a channel at a time.  Wait until the
       other party finishes before answering.

MONITORING

Pressing LOCK has the same effect as holding down TALK.  Use LOCK to set
the intercom for monitoring another station's location (such as a nursery
or playroom), or when other one-way communication is needed.  Follow these
instructions to monitor another location.

1.  Press LOCK on the station in the area you want to monitor.  The talk
    indicator lights.

Note:  The talk indicator lights as long as LOCK is on.  This lets you
       know that the station is transmitting to another station.

2.  Listen from your station.

3.  To release the lock, press TALK on the monitored station.  The talk
    indicator goes out.

Note:  You cannot call or talk to the locked station while LOCK is on.
       Remember to release the lock when you finish monitoring.

USING ADDITIONAL STATIONS

You can add additional stations to the system.  Any Radio Shack 3-channel
intercom that transmits on the same frequencies is compatible.  The
intercom's channels and transmitting frequencies are shown below.
