Four hours coutinuous use.

Seven days when the handset is in the standby mode.

When the battery charge becomes low

When the voltage of battery pack in the handset is very low and needs to be charged, the phone is programmed to eliminate functions in order to save power. If the battery charge becomes “Low Battery” appears on the LCD, and if the phone is in use, the handset beeps. Complete your conversation as quickly as possible and return the handset to the base unit for charging.

Rechargeable batteries have a memory effect that reduces standby and talk time. To avoid this memory effect, on a monthly basis, use the phone until

Low Battery” appears. Then charge the battery for more than 17 hours.

Cleaning the battery contacts

To maintain a good charge, it is important to clean the battery contacts on the handset and base unit about once a month. Use a pencil eraser or other contact cleaner.

Do not use liquids or solvents.
