Installation
²If the CHARGING indicator does not light when you place the handset on the base, be sure the battery pack and AC adapter are correctly and securely connected.
Also, check the charging contacts on the handset and the base. If the contacts are dirty or tarnished, clean them with a pencil eraser.

²If the battery pack gets completely discharged or the base loses power while the handset is away from it, the security access- protection code needs to be reset. To reset the code, place the handset on the base for about 30 seconds. If it was the handset that lost power, leave the handset on the base to charge the bat- tery pack.
²If the battery pack gets weak during a call, the handset sounds 4 beeps every 30 seconds. If this happens, you cannot make another call on the phone until you recharge the battery pack.
²About once a month, fully discharge the battery pack by keep- ing the handset off the base until the LOW BATT indicator lights. Otherwise, the battery pack loses its ability to fully recharge.
²If you are not going to use your phone for an extended period of time, disconnect the battery pack. This increases the battery pack’s usable life.
²The supplied battery pack should last for about a year. When it loses its ability to fully recharge, order a replacement battery pack through your local RadioShack store (see “Replacing the Handset Battery Pack” on Page 46).
