THE FCC WANTS YOU TO KNOW

In the unlikely event that your phone causes problems on the phone line, the phone company can temporarily discontinue your service. If this hap- pens, the phone company attempts to notify you in advance. If advance no- tice is not practical, the phone compa- ny notifies you as soon as possible and advises you of your right to file a com- plaint with the FCC.

Also, the phone company can make changes to its lines, equipment, opera- tions, or procedures that could affect the operation of this telephone. The telephone company notifies you of these changes in advance, so you can take the necessary steps to prevent in- terruption of your telephone 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 the inter- ference.

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 Ra- dioShack store for help

Some cordless phones operate at fre- quencies that might cause interference to nearby TVs and VCRs. To minimize or prevent such interference, the base of the cordless phone should not be placed near or on top of a TV or VCR.

LIGHTNING

Your telephone has built-in lightning protection to reduce the risk of damage from surges in telephone line and pow- er line current. This lightning protection meets or exceeds FCC requirements. However, lightning striking the tele- phone or power lines can damage your telephone.

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.
