Troubleshooting

The batteries 
will not hold a 
charge.

•  If the cordless handset is in its telephone 

base or charger and the charge light does 
not come on, refer to 

off in this Troubleshooting guide.

•  Charge the battery in the cordless handset 

for at least 16 hours. For optimum daily 
performance, return the cordless handset to 
its base when not in use.

•  You may need to purchase a new battery. 

Please refer to 

charging, pages 6-7, in this user’s manual.

I get noise, 
static, or weak 
signal even 
when I’m near 
the telephone 
base.

•  If you subscribe to high-speed Internet 

service (digital subscriber line - DSL) through 
your telephone lines, you must install a 
DSL filter between the telephone base and 
the telephone wall jack. The filter prevents 
noise and caller ID problems caused by DSL 
interference. Please contact your DSL service 
provider for more information about  
DSL filters.

•  You may be able to improve the 

performance of your cordless phone by 
installing your new telephone base as far 
as possible from any other existing cordless 
telephone system that may already be 
installed.

•  Other electronic products can cause 

interference to your cordless phone. Try 
installing your phone as far away from the 
following electronic devices as possible: 
television sets, VCRs, or other cordless 
telephones.
