Test a working telephone at the telephone wall jack. If another telephone has the 

same problem, the problem is in the telephone wall jack. Contact your telephone 

service provider (charges may apply).
The telephone line cord may be malfunctioning. Install a new telephone line cord.
Reinstall the battery and place the handset in the telephone base.
Wait for the handset to synchronize with the telephone base. Allow up to one minute 

for this to take place.

Make sure the power cord is securely plugged into the telephone base. Plug the 

telephone base into a different working electrical outlet not controlled by a wall switch.
Move the handset closer to the telephone base. It may be out of range.
Reset the telephone base by unplugging the electrical power to the base. Wait for 15 

seconds and plug it back in again. Allow up to one minute for the cordless handset 

and the telephone base to synchronize.
Other electronic products can cause interference to your cordless telephone.   

Install your telephone as far away from these electronic devices as possible:  

wireless routers, radios, radio towers, pager towers, cellular telephones, intercoms, 

room monitors, televisions, personal computers, kitchen appliances and other 

cordless telephones.

The handset may be out of range. Move it closer to 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 line cord 

and the telephone wall jack. The filter prevents noise and caller ID problems caused 

by DSL interference. Contact your DSL service provider for more information about 

DSL filters.
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.
Other electronic products can cause interference to your cordless telephone. Install 

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.
If your telephone is plugged in with a modem or a surge protector, plug the telephone 

(or modem/surge protector) into a different location. If this doesn’t solve the problem, 

relocate your telephone or modem farther apart from each other, or use a different 

surge protector.  
The location of your telephone base can impact the performance of your cordless 

phone. For better reception, install the telephone base in a centralized location within 

your home or office, away from walls or other obstructions. In many environments, 

elevating the telephone base improves overall performance.
