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 and unplug your phone and discon- nect the handset battery. If the interfer- ence goes away, your phone is causing the interference.

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 your local RadioShack store for help

If you cannot eliminate the interfer- ence, the FCC requires that you stop using your phone.

LIGHTNING

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 exceed FCC requirements. However, lightning strik- ing the phone lines can damage your phone.

Lightning damage is not common. Nevertheless, if you live in an area that has severe electrical storms, we sug- gest that you unplug your phone during storms to reduce the possibility of damage.
