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 li ne 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 t hey are c onnected to t he 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 feedbac k which c reates a squealing sound.
Caution:
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.
