Operating Range; Changing Channels - AT&T 7720 User Manual

This cordless telephone answering system operates at the maximum
power allowed by the Federal Communications Commission (FCC). Even
so, the handset and base can communicate over only a certain distance—
which can vary with the locations of the base and handset, the weather,
and the construction of your home or office. For best performance, make
sure the base antenna is fully upright, as shown in the INSTALLATION
section of this manual.
If the handset is moved to a point where the base and handset can no
longer communicate, you will be "out of range." The handset will sound
two short beeps to indicate this when you try to make a call. Move closer
to the base to restore normal operation.
If you receive a call while you are out of range, the handset might not
ring—or, if it does ring, the call might not connect when you press P.
Move closer to the base, then press P again to answer the call.
If you move out of range during a phone conversation, you will
hear noise or interference. To improve reception, move closer to the
base.
If you attempt to hang up while you are out of range, the phone will
be left "off the hook." To hang up, walk back into range, periodically
pressing P until the PHONE light goes off.

Changing Channels

This cordless telephone has an advanced 25-channel AutoSelect
that minimizes the chance of interference. Every time you answer or
make a call, the AutoSelect feature searches for and selects a clear
channel.
In the unlikely event that you notice noise or interference while using the
handset:
Press h.
