Also, the phone company can make changes to its lines, equipment, oper- ations, or procedures that could affect the operation of the phone. The phone company notifies you of these chang- es in advance, so you can take the necessary steps to prevent interrup- tion of your phone service.

Your phone might cause TV or radio interference even when it is operating properly. To determine whether your phone is causing the interference, turn off your phone. If the interference goes away, your phone is causing it. Try to eliminate the interference by:

•Moving your phone away from the receiver

•Connecting your phone to an AC outlet that is on a different electri- cal circuit from the receiver

•Contacting a radio/TV technician or your local RadioShack store for help

Your phone has built-in protection cir- cuits to reduce the risk of damage from surges in phone line current. These protection circuits meet or ex- ceed FCC requirements. However, lightning striking the phone lines can damage your phone.

Lighting damage is not common. Nev- ertheless, if you live an area that has severe electrical storms, we suggest that you unplug your phone during storms to reduce the possibility of damage.
