Charging and Operating Times
Charging time: (empty batteries) to full capacity in approx. 6 to 7 hours.
Talk time: >10 hours (with fully charged batteries).
Standby time: >100 hours (with fully charged batteries).
Charge Display
The charge status of the batteries is indicated on the display. This means:
batteries fully charged (80 – 100 %)
batteries 60 – 79 %
batteries 40 – 59 %
batteries 20 – 39 %
batteries 0 – 19 %
(frame flashes) batteries are empty: an alert tone is also given.
Battery Capacity Icon
When batteries are replaced, no icon will be displayed before a charging cycle has been
completed, except when almost empty batteries are inserted in the phone, then the icon will be
shown immediately.
When the battery capacity icon is displayed, the indication is reliable.
If the charged batteries are inserted, the batteries can become hot during the first charge cycle,
and if the fully charged batteries are removed from the phone and inserted again, the batteries
can become overcharged.
Charge Warning
When the batteries’ capacity is almost exhausted, an acoustic warning is given in the form of 3
short ”beep” signals (only during a call). Upon receiving the beep approximately 5 minutes of
talk time is left.
