Notes:

•You can place the handset on the base face down or face up without removing the belt clip. If you want to use the hanging hole on the back of the handset to place the handset on the wall-mounted base face-up, re- move the belt clip (see “Removing the Belt Clip” on Page 13). However, the battery pack will not fully charge in this position.

•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 when you press TALK. If this happens, re- turn the handset to the base for about 6 seconds. This resets the se- curity access protection code.

•If the CHARGE 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.

•If 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. If it

was the handset that lost power, leave the handset on the base to charge the battery pack.

•If the battery pack gets weak during a call, the handset beeps once ev- ery 16 seconds. If this happens, you cannot make another call on the phone until you recharge the battery pack.

•About once a month, fully discharge the battery pack by keeping the

handset off the base until and LOW BATTERY appear. Otherwise, the battery pack loses its ability to fully recharge.

•To avoid damage to the battery pack, always recharge the handset before battery power grows too

weak to display .

•If you are not going to use your phone for an extended period of time, disconnect the battery pack. This increases the battery pack’s us- able life.

•The supplied battery pack should last for about a year. When it loses its ability to fully recharge, order a replacement battery pack from your local RadioShack store (see “Re- placing the Battery Pack” on Page 26).
