•When you first use the phone after charging or recharging the battery pack, the phone might not work and you might hear an error tone. If this happens, return the handset to the base for a few seconds.

•If the battery pack loses its charge completely or the base loses pow- er while the handset is away from it, the security access-protection code needs to be reset. To reset the security code, place the hand- set on the base. If it was the hand- set that lost power, leave the handset on the base to charge the battery pack.

•About once a month, fully dis- charge the battery pack by keep- ing the handset off the base until the TALK/BATT LOW indicator flashes. Otherwise, the battery pack loses its ability to fully re- charge.

•If the TALK/BATT LOW indicator does not light and the phone does not work, recharge the battery pack. (The battery power might be too low to light the indicator.)

•The supplied battery pack should last for about a year. When the battery pack loses its ability to ful- ly recharge, order a replacement battery pack from your local Ra- dioShack store (see “Replacing the Battery Pack” on Page 23).

SETTING THE DIALING MODE

Set DIAL MODE on the back of the base for the type of service you have. If you are not sure which type you have, do this test.

1.Set DIAL MODE to T.

2.Press SPEAKER and listen for a dial tone from the speakerphone. The IN USE indicator turns on.

3.Press any number other than 0.

Note: If your phone system re- quires that you dial an access code (9, for example) before you dial an outside number, do not press the access code either.

If the dial tone stops, you have touch-tone service. Leave DIAL MODE set to T.

If the dial tone continues, you have pulse service. Set DIAL MODE to P.

4.Press SPEAKER again. The IN USE indicator turns off.
