Troubleshooting

 

Disconnect the telephone base from the modular jack and

 

 

plug in a corded telephone. If calls are still not clear, the

 

 

problem is probably in the wiring or local service. Contact

 

 

your local service company (charges may apply).

 

Other cordless telephones and 802.11 wireless routers that

 

 

are used for home computer networks both use internal

 

 

radios to communicate. The radios may interfere with one

 

 

another. You can improve the performance of your cordless

 

 

telephones and your router by:

 

 

a. Positioning your new telephone as far away from any

 

 

other already installed cordless telephone in your home

 

 

as possible. This will hinder the interference of the two

 

 

systems with one another.

 

 

b. Positioning your telephone base as far as possible from

 

 

your router, computer or any other computer devices.

 

 

c. Selecting channels 4 through 10 for your router (refer to

 

 

your router’s user manual for more information).

 

Do you have DSL service? If yes, you need to have a DSL

 

 

filter installed at every telephone jack that has a telephone

 

 

connected to it. Contact your DSL service provider for filter
