Ericsson T39 User Manual page 9

To indicate charging:
• the battery meter in the display pulses continuously.
• the indicator on top of the phone shows a steady red light (or green,
if the phone is switched on).
• Optimized charging is shown briefly in the display.
Note:
It may take up to 30 minutes before you get an indication of
charging in the display, if you are charging a new battery that is
completely flat, or a battery that has not been used for a long time.
When the battery is fully charged, the battery meter in the display is
full and the indicator on top of the phone shows a steady green light.
For the best charging, talk and standby times in the long run, we
recommend that you use only Ericsson-approved batteries with your
phone. Please note that use of non-Ericsson-approved batteries will
invalidate your phone warranty.
Disconnecting the Charger

Removing the Battery
1. Slide the release catch up. 2. Lift the battery away from
