Indoor/Outdoor Modular Intercom System

43-3101

OWNER’S MANUAL — Please read before using this equipment.

Your Indoor/Outdoor Modular Intercom System operates as a two-tone doorbell intercom and an indoor intercom. The doorbell is simple to install without wiring and you can add additional stations.

PREPARATION

Installing the Doorbell’s Batteries

Your doorbell intercom uses four AA batteries (not supplied) for power. For the best performance and longest life, we recommend RadioShack alkaline batteries.

Caution: 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.

1.Use a Phillips screwdriver to loosen the screws in the doorbell intercom’s battery compartment cover, then lift the cover off.

2.Insert four AA batteries into the compartment as indicated by the polarity symbols (+ and – ) marked inside.

3.Replace the cover and tighten the screws.

Hint: For convenience, set the channel (see “Setting the Channel”) while you have the battery cover removed.

Replace the batteries when the battery level is low and the doorbell sends an alert tone to the indoor intercom. The POWER indicator on the indoor intercom flashes until you replace the batteries.

Warning: Dispose of old batteries promptly and properly. Do not burn or bury them.

Caution: If you do not plan to use the doorbell for two weeks or longer, remove the batteries. Batteries can leak chemicals that can destroy electronic parts.

If the doorbell unit operates under severe cold weather, use a lithuim type AA battery.

Setting the Channel

The doorbell and indoor intercoms have three selectable operation channels to prevent interference from similar products nearby. Select the same channel for both the doorbell intercom and the indoor intercom.

On the doorbell intercom, slide CH inside the battery compartment to 1 (49.835MHz), 2 (49.860MHz), or 3 (49.885MHz).

On the back of the indoor intercom, set OUTDOOR CHANNEL to the same channel number (1, 2 or 3) you chose for the doorbell intercom.

Note: If the doorbell occasionally sounds without anyone pressing BELL on the doorbell, change the channel settings.

Changing the Doorbell’s Tone

Use a small flat-blade screwdriver to carefully pull out the jumper TONE switch located in the battery compartment, then insert the jumper TONE switch into the other two pins.
