• In some installations that have fiber optic service
(digital service to the building, analog service
within the building) the signals to the extensions
might not support the call privacy feature.
• The Do Not Disturb feature is activated at the
extension you are calling.
• There is a call on hold at this extension. Press
and release the LINE button of the call on hold
to return to the call and turn off the reminder
beep.
• This phone operates during a power failure if
a working battery is installed. You are able to
answer calls with the handset, and dial calls
using the dial pad keys and the one-touch or
redial features. No other features work until
power is restored. All programming is retained
during a power failure.
• The phone has been disconnected from AC
power. When AC power is restored, the screen
returns to the usual display. One-touch and redial
numbers are retained until power is restored.
• Make sure the power cord is connected to both
the phone and an electrical outlet not controlled
by a wall switch.
• If you have a headset plugged into the telephone,
try unplugging it and firmly plugging it in again.
• Disconnect the telephone base from the modular
jack and plug in another corded telephone. If calls
are still not clear, the problem is probably in the
wiring or local service. Contact your local service
company (charges may apply).
• If you are using the speakerphone when this
problem occurs, eliminate any background
noise. Noise from the television, radio, or other
appliances might cause the speakerphone to
cut in and out. Try engaging the [MUTE] button
when you are not speaking or eliminating the
background noise.
