OpenPhone 26/27 Charging the Battery
OpenPhone 27: up to 140 hours
(fully charged)
Note: Batteries with an unknown
charging status are fully charged in
approx. 14 hours.
Charge Display
The charging status of the battery is
shown in the display as follows:
Your handset has a battery manage-
ment system that has to determine
the limits of the battery charging
status before it can display an accu-
rate charge level.
When the battery has been
replaced, the charge level is not
correctly displayed until a whole
charge and discharge cycle has
been completed.
When the handset is in the charging
station, the flashing or lit sections
indicate charging and the charge
level.
Charge warning
When the battery capacity is nearly
exhausted, the battery symbol will
flash in the display.
If you are making a call at the time,
you still have up to three minutes of
talk time before the handset
switches itself off. If you are not
making a call and the handset is not
in the charging station, “Battery
empty” appears in the display. You
can no longer make a telephone call
now.
