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 on a desk, shelf, or table, or mo unt it
on a wall.

Important:

• You must connect all of the stations to AC outlets
originating from 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 t hey are c onnected to t he same
phase of a power line transformer.

• To use the stations in a home or office with more than
one phase of a power line transformer, you need a
whole house converter, such as RadioShack Cat. No.
61-2401.

• Make sure you install the stations at least 10 feet
apart. Placing the stations too close together pro­duces feedback which creates 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.
