43-490.fm Page 5 Friday, August 13, 1999 9:52 AM INSTALLATION You can install the stations almost anywhere there is a standard AC outlet. Simply plug each station into an AC outlet, then place it directly on a desk, shelf, or table, or mount it on a wall. Important: You must connect all of the stations to AC outlets connected to the same power line transformer. All AC outlets in most residential and many commercial properties are connected to the same power line transformer.
43-490.fm Page 6 Friday, August 13, 1999 9:52 AM MOUNTING THE STATIONS To mount a station on the wall, you need two screws (not supplied). The screws must have heads that fit into the keyhole slots on the bottom of the stations. Follow these steps to mount a station on the wall. 1. Select a location for the station. Then mark the mounting screw locations on the wall 2 9/16 inches (65.80 mm) apart, one above the other. 2. Drill two holes at the marked locations. 3.
43-490.fm Page 7 Friday, August 13, 1999 9:52 AM OPERATION SETTING THE CHANNEL Each station has three channels so you can select which station or stations you want to communicate with. You can also use a station to monitor sounds near another station. For example, you could set the station you installed in the kitchen to Channel A, a station you installed in the family room to Channel B, and a station you installed in a bedroom to Channel C.
43-490.fm Page 8 Friday, August 13, 1999 9:52 AM • If you want to use a station to communicate with only one of the other stations, set only those stations to the same channel. Note: To keep a record of each station’s channel letter, insert a pointed object such as the tip of a pencil into the hole on the cover above the channel selector to remove it. Then, write the location of each station and the channel each is set to in the space provided. Use a pencil in case you want to change it later.
43-490.fm Page 9 Friday, August 13, 1999 9:52 AM CALLING ANOTHER STATION 1. Be sure the stations you plan to use are turned on and adjusted to the desired volume. 2. Set the channel selector to the channel (A, B, or C) for the station(s) you are calling. 3. Press CALL. Each station that is turned on and set to the selected channel sounds a tone.
43-490.fm Page 10 Friday, August 13, 1999 9:52 AM 4. Hold down TALK and speak in a normal voice. When you finish speaking, release TALK and listen for the response.
43-490.fm Page 11 Friday, August 13, 1999 9:52 AM Notes: • Only one party can talk on a channel at a time. • The TALK indicator on the station you are using remains lit as long as you hold down TALK or CALL, or when you press LOCK (see “Monitoring”). • If your voice sounds distorted, you might be speaking too loudly or too close to the microphone. • Be sure to set the channel selector back to your designated channel after you finish talking, so others can easily reach you.

Note: The TALK indicator stays lit until you press CALL or TALK. This lets you know that the station is transmitting to another station. 2. Set the channel selector on both stations to the same channel. 3. When you finish monitoring, press TALK or CALL on the station in the area you are monitoring to release the lock. The TALK indicator turns off.
