I get noise, static, or weak signal even when I’m near the tel- ephone base

Other cordless phones and 802.11 wireless routers that are used for home computer networks both use internal radios to communicate. The radios may inter- fere with one another. You can improve the perform- ance of your cordless phones and your router by:

a.Positioning your new phone as far away as possible from any other existing cordless telephone system that is already installed in your home to avoid the two systems from interfering with each other.

b.Positioning your telephone base as far as possible from your router, computer or any other computer devices.

c.Selecting channels four through 10 for your router (refer to your router’s user’s manual for more infor- mation).

Other electronic products can cause interference to your cordless phone. Try installing your phone as far away from the following electronic devices as possible: wireless routers, radios, radio towers, pager towers, cell phones, intercoms, room monitors, televisions, personal computers, kitchen appliances and other cordless phones.

Microwaves operate on the same frequency as your phone. It is normal to experience static on your phone while the microwave oven is operating. Do not install this phone in the same outlet or near a microwave oven.

If your phone is plugged in with a modem or a surge protector, plug the phone (or modem/surge protector) into a different location. If this solves the problem, re- locate your phone or modem farther apart from one another, or use a different surge protector.

Relocate your phone to a higher location. The phone will likely have better reception when not installed in a low area.

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).
