There is noise or interference during a call.
You may be receiving radio signals from another cordless telephone or
other source of interference such as a TV, fluorescent lighting, or an
electrical storm. Make sure that the base unit is not plugged into a
circuit that also powers a major appliance. Move closer to the base
unit. Also, be sure that the antenna on the unit is fully extended. If the
problem still persists, change to a different channel by pressing the
Channel key continuously until you find the best available channel for
your conversation.
When you speak into your phone, your voice is accompanied by a
high-pitched “squeal”.
The earpiece volume is set too high. The “squeal” is caused when your
phone’s microphone picks up your voice from the speaker. Adjust the
volume on the handset to a lower level.
The CHARGE 1 indicator does not light when the handset is
placed in the charging unit.
Make sure the AC adapter is plugged into the base unit and electrical
wall outlet. Ensure that the charging contacts on the handset and
charging unit are clean and that the handset is properly seated in the
charging unit.
