Eliminate any background noise. Noise from a
television, radio, or other appliances may cause the
telephone to not dial out properly. If you cannot
eliminate the background noise, first try muting the
telephone before dialing, or dialing from another room
in your home with less background noise.
There is no spare battery in the telephone or the
battery power is low.
Remove and re-install the battery and use it normally.
If the above measures do not correct the problem, the
battery may need to be replaced.
Make sure the ringer is on (see page 32).
Make sure the telephone line cord and power adapter
are plugged in properly (pages 10-11).
There may be too many extension telephones on
the telephone line to allow all of them to ring
simultaneously. Try unplugging some of them.
If the other telephones in your home are having the
same problem, the problem is in the wiring or local
service. Contact the local telephone company (charges
may apply).
Other electronic products can cause interference
to your telephone. Try installing your telephone as
far away as possible from the following electronic
devices: wireless routers, radios, radio towers, pager
towers, cellular telephones, digital telephones, room
monitors, televisions, VCRs, personal computers, kitchen
appliances, and other cordless telephones.
Test a working telephone at the same telephone jack. If
another telephone has the same problem, the problem
is in the telephone jack. Contact your local telephone
company (charges may apply).
The telephone line cord might be malfunctioning. Try
installing a new telephone line cord.
Appliances or other cordless telephones plugged into
the same circuit as the telephone base can cause
interference. Try moving the appliance or telephone
base to another outlet.
