Even when the battery pack is not being used, it will gradually discharge over a long period of time. For optimum performance, be sure to return the handset to the base unit after a telephone call.

If you must replace the battery pack during a telephone call, complete the replacement of the battery pack within 30 seconds, and you can return to the original call.

Battery use time (per charge)

From fully charged

6 hours continuous use

10 days when the handset is in the standby mode

Low Battery Alert

When the battery pack is very low and needs to be charged, the phone is programmed to eliminate functions in order to save power. If the phone is not in use, “Low Battery” appears on the LCD and none of the keys will operate.

If the phone is in use, “Low Battery” flashes and the handset beeps. Complete your conversation as quickly as possible and return the handset to the base unit for charging.

The last number dialed in the redial memory, the names and the numbers stored in the memory locations are retained for up to 2 minutes while you replace the battery pack.

Cleaning the Battery Charging Contacts

To maintain a good charge, it is important to clean the battery contacts on the handset and base unit with a dry cloth or a pencil eraser about once month.

Do not use any liquids or solvents.
