Maintenance and Troubleshooting
If you are using the handset lifter, LIFTER
MODE must be selected on the headset
base (page 11). See the TL7000 handset
lifter manual for instructions on setting
the LIFTER AUDIO ADJUST.
If the previous suggestions do not work,
disconnect the headset base from the
telephone jack and connect a different
phone. If there is no dial tone on that
phone either, the problem is in your
wiring or local service. Contact your local
telephone company.
• Your telephone line cord might be
malfunctioning. Try installing a new
telephone line cord.
Nothing
happens when
I slide the
LIFTER AUDIO
ADJUST to get
a clear dial
tone.
There is no need to change the LIFTER
AUDIO ADJUST switch when you use NO
LIFTER MODE. If you cannot get a dial
tone, try all the suggestions above.
If you are using a handset lifter, see the
TL7000 handset lifter user’s manual for
instructions on setting the LIFTER AUDIO
ADJUST.
