PREPARATION You can power your intercoms using four AA batteries (not supplied) or the supplied

AC-to-DC adapter. Installing the 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. Remove the battery compartment door by sliding it toward the bottom of the unit.

2. Place four AA batteries in the compartment according to the polarity symbols (+ and

-) marked inside.

3. Replace the cover. When the POWER BATT LOW LED flashes during the operation of the intercom,

replace the batteries. Warning: Dispose of old batteries promptly and properly. Do not burn or bury them. Using AC-to-DC power Open battery compartment and remove batteries or make sure RECHARGE ON/OFF

switch is set to OFF. Insert the barrel plug of the adapter into DC 9V jack on the back of the unit. Plug the other end of the adapter to a standard AC outlet. Using Rechargeable Batteries

1. Remove the battery compartment door.

2. Install the rechargeable batteries according to the polarity symbols (+ and -) marked on the battery compartment.

3. Slide RECHARGE ON/OFF to ON.

4. Replace the cover.

Caution: Do not attempt to recharge alkaline batteries and regular batteries. Notes: O It takes about 10-12 hours to completely recharge the batteries. O The built-in charger is designed for batteries with 1.2V 1500mAh. O Once the unit has been turned on, the batteries will be automatically charged during

the transmission mode and standby. O The battery life for rechargeable battery (Ni-MH, 1500mA) is about 37 hours . Mounting the Intercom You can install the stations almost anywhere and place it directly on a desk, shelf, and

table or on a wall.

Follow these steps to mount the intercom on a wall. Note: You need two screws (not supplied) with heads that fit into the keyhole slots on

the bottom of the intercom.

1. Mark the mounting screw location 3 15/16 inches (100 mm) apart.

2. If you are installing on a drywall, use the correct dry wall screw lags for the screw size you are using.

3. Drill a hole for the drywall lag as recommended by the vendor at each mark.

4. Insert each drywall lag and tap with hammer to make it flush with wall.

5. Thread a screw into each hole or drywall insert until the left screw’s head extends about ¼ inch (6.5 mm) from the wall and the right screw’s head extends about 1/8 inch (3.5 mm) from the wall.

6. Align the keyhole slots on the bottom of the intercom with the screw heads in the wall, then slide the intercom to secure it. Lift and rotate the antenna upward.

Important: Be sure you install the stations at least 10 feet away from each other. Placing the stations too close together produces feedback (a squeal or howl from the speakers). The stations can transmit up to 200 feet line of sight.

Setting the Channel Each station has 4 pre-programmed channels, so you can select which channel you

want to communicate on by setting the actuators of the channel selector (DIP switch) with different combination of ON and OFF.

Set the channel selector on each station as follows: O If you want all the stations to communicate with each other at the same time, set all

stations to the same channel. O If you want to use a station to communicate with only one of the other stations, set

only those two stations to the same channel.
