Responding to Low Battery Indicators

When using the portable unit, you will be notified of a low battery condition by both an audible tone and a flashing LOW BATTERY indicator. These indicators will be activated approximately four minutes before the battery pack is completely discharged.

If you try to turn on the portable unit when it is experiencing a low battery condition, the ON/OFF/MUTE indicator will flash 3 times and turn off.

Once you notice the low battery indicators, immedi- ately recharge the battery pack by placing the portable unit in the cradle of the base unit. If the battery pack is allowed to discharge completely, you may lose the phone numbers stored in memory speed dial.

Once the battery pack is recharged, the low battery indicators will turn off.

The headpiece may be used while the battery pack in the portable unit is being recharged (see section on Operating the Portable Unit From the Cradle).

Operating the Portable Unit From the Cradle

The portable unit and headpiece will operate when seated in the cradle of the base unit, even when the battery pack is discharged.
