sure the power cord is securely plugged in.

 

The cordless handset may be too far from the telephone

 

 

base.

 

Charge the battery in the cordless handset for at least

 

 

16 hours. For optimum daily performance, return the

 

 

cordless handset to the telephone base or charger when

 

 

not in use.

 

You may have too many extension phones on

 

 

your telephone line to allow all of them to ring

 

 

simultaneously. Try unplugging some of the other

 

 

phones.

 

The layout of your home or office might be limiting

 

 

the operating range. Try moving the telephone base to

 

 

another location, preferably on an upper floor.

 

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).

 

Test a working phone at the phone jack. If another

 

 

phone has the same problem, the problem is the phone

 

 

jack. Contact your local telephone company (charges

 

 

may apply).

 

Other electronic products can cause interference with

 

 

your cordless phone. Try installing your phone as

 

 

far away as possible from electronic devices such as

 

 

television sets, VCRs, or other cordless telephones.
