Troubleshooting
Problem Suggestion
There is no dial tone. First, try all the above suggestions.
Move the cordless handset closer to the telephone base. It might be out of range.
The telephone line cord might be malfunctioning. Try installing a new telephone line cord.
Disconnect the telephone base from the telephone jack and connect a different telephone.
If there is no dial tone on the telephone either, the problem is in your wiring or local service.
Contact your local telephone company.

The telephone does not
ring when there is an
incoming call.
Make sure the ringer is on. (See page 10 for handset and page 28 for telephone base).
Make sure the telephone line cord and power adapter are plugged in properly (see page 2).
The cordless handset may be too far from the telephone base. Move it closer to the telephone base.
There may be too many extension phones 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 cordless 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, intercoms, room monitors,
televisions, VCRs, personal computers, kitchen appliances, and other cordless telephones.
Test a working telephone at the 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.
Re-install the battery and place the cordless handset in the telephone base.
Wait for the cordless handset to synchronize with the telephone base. Allow up to one minute
for this to take place.
