Your phone might cause TV or radio interference even when it is operat- ing properly. To determine whether your phone is causing the interfer- ence, turn off and unplug your phone and disconnect the handset battery. If the interference 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 elec- trical circuit from the receiver

Contacting your local Radio Shack 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 circuits 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.

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