Troubleshooting

Eliminate any background noise. Noise from a television, radio or other appliances may cause the phone to not dial out properly. If you cannot eliminate the background noise, first try muting the cordless handset before dialing, or dialing from another room in your home with less background noise.

If the other phones in your home are having the same problem, the problem is in your wiring or local service. Contact your local telephone company (charges may apply).

electrical outlet not controlled by a wall switch.

normally

Move the cordless handset closer to the telephone base.

 

 

 

 

 

You might have moved out of range.

 

 

Reset the telephone base. Unplug the unit’s electrical

 

 

 

power. Wait for 15 seconds then plug it back in.

 

 

 

Allow up to one minute for the cordless handset and

 

 

 

telephone base to reset.

 

 

Other electronic products can cause interference to

 

 

 

your cordless phone. Try installing your phone as far

 

 

 

away from these types of electronic devices as possible:

 

 

 

television sets, VCRs, or other cordless telephones.

 

 

 

 

Calls are cut

If you are on a call during an AC power failure, (using

off

 

the backup base batteries,) and AC power returns, the

 

 

 

call will be ended. Detach the AC power cord before

 

 

 

making or answering calls to avoid this problem. Be

 

 

 

sure to plug it back in when power is restored.

 

 

If a power failure happens during a call on the cordless

 

 

 

handset or on speakerphone mode, the call will be

 

 

 

disconnected immediately. You can still make and

 

 

 

receive calls with limited functions if backup batteries

 

 

 

are installed (see page 5).
