Troubleshooting
I hear other
calls when using
the telephone. • Disconnect the telephone base from the telephone jack.
Plug in a different telephone. If you still hear other calls,
the problem is probably in the wiring or local service.
Call your local telephone company.
Automatic redial
interrupted. • If the telephone rings during the automatic redial
sequence, you will cancel it if you lift the handset,
press
SPEAKER or press HEADSET (if a headset is
connected) to take the call.
• Lifting the handset, pressing SPEAKER or pressing
HEADSET (if a headset is connected) will cancel
automatic redial.
• Low battery power can affect automatic redial. For
information about changing batteries, see Battery
installation on page 5.
Speakerphone
does not
work while
an extension
telephone is in
use. • The speakerphone is powered by the current in the
telephone line cord connected to your wall jack. The
speakerphone might not work if you are on a call on
a line-powered extension telephone and try to use the
983 speakerphone at the same time. There may not be
enough power in the line current to support both the
speakerphone and the extension telephone. Try using the
handset for calls like this.
Telephone does
not work with
headset. • Make sure four new AA alkaline batteries are properly
installed (see Battery installation on page 5).
• Use only an industry standard two-band 2.5 mm head-
set (purchased separately). For best results, use an AT&T
two-band 2.5 mm headset.
Warning tone
sounds when lift
the handset or
press
SPEAKER.
• Make sure four new AA alkaline batteries are properly
installed (see Battery installation on page 5).
