CAUTION ! 43-491.fm Page 3 Friday, August 13, 1999 9:58 AM ! This symbol is intended to alert you to the presence of uninsulated dangerous voltage within the product’s enclosure that might be of sufficient magnitude to constitute a risk of electric shock. Do not open the product’s case. This symbol is intended to inform you that important operating and maintenance instructions are included in the literature accompanying this product. The graphical symbols with supplemental markings are on the bottom of the unit. 3 43-491.fm Page 4 Friday, August 13, 1999 9:58 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 phase of a power line transformer. All AC outlets in most residential and many commercial properties are connected to the same phase of a power line transformer. • Stations can transmit up to 300 feet and between buildings as long as they are connected to the same phase of a power line transformer. • Make sure you install the stations at least 10 feet away from each other. Placing the stations too close together produces feedback which creates a squealing sound. Caution: To prevent electric shock, one blade on the power cord’s plug is wider than the other so the plug fits into the outlet only one way. If you cannot easily insert the plug, turn it over and try again. Do not force it. 4 43-491.fm Page 5 Friday, August 13, 1999 9:58 AM MOUNTING THE STATIONS To mount a station on the wall, you need two screws (not supplied) with heads that fit into the keyhole slots on the bottom of the stations. Follow these steps to mount a station on the wall. 1. Mark the mounting screw locations 29/16 inches (65.08 mm) apart, one above the other. 2. Drill a hole at each marked location. 3. Thread a screw into each hole until the screw’s head extends about 1/8 inch from the wall. 4. Align the keyhole slots on the bottom of the station with the screw heads in the wall, then slide the station down to secure it. 5 43-491.fm Page 6 Friday, August 13, 1999 9:58 AM OPERATION TURNING A STATION ON AND OFF/ ADJUSTING THE VOLUME Rotate VOLUME to the left until it clicks.
