Preparation

Battery performance

After your Panasonic battery is fully charged, you can expect the following performance:

Operation	Operating time
While in use	Up to 5 hours
(talking)

While not in use	Up to 11 days
(standby)*1
While using the	Up to 3 hours
Clarity Booster
feature (page 20)

*1 Handset is off the base unit or charger but not in use.

Note:

L Battery power is consumed whenever the handset is off the base unit or charger, even when the handset is not in use. The longer you leave the handset off the base unit or charger, the shorter you can actually talk on the handset. Actual battery performance depends on a combination of how often the handset is in use and how often it is not in use.

L Once the battery is fully charged, you do not have to charge it again until “Recharge battery” is displayed or 7flashes. This will maximize the battery life.

Battery replacement

If battery performance diminishes, make sure you have cleaned the charge contacts and fully charged the battery. The battery needs to be replaced if any of the following are displayed after a few phone calls even when you have fully charged the battery.

–“Recharge battery”

–7(flashing)

–“Charge for 6h”

–8

L Use only the rechargeable Panasonic battery noted on page 5.
