The Basics
The handset antenna is located on the back, above
the ringer speaker. For maximum communication
range, do not hold the handset in such a way as to
cover the antenna by your hand. Also, place the
handset in the upright position while not in use so the
antenna can pick up the signals from the base.
When there is an obstacle such as a metal or
concrete wall between the handset and the base, the
operation might be affected. Try to keep it free from
obstructions.
Your telephone connects directly to a modular
telephone line jack. If your telephone wiring does
not have a modular jack, you can update the wiring
yourself using jacks and adapters (available at your
local RadioShack store), or have the telephone
company update the wiring for you. You must use
compatible modular jacks that are compliant with Part
68 of FCC Rules.
NOTE
The USOC number of the jack to be
installed is RJ11C (or RJ11W for a wall
plate jack).
