4 Preparation and operation
4.11.1 General information
• Battery running time depends on ventilation settings and ambient temperature.
• When planning your time, take account of the fact that battery running time is
considerably reduced at low or very high outdoor temperatures.
• When the
Battery capacity critical
alarm
appears, only about 10 % capacity
remains. When the
Battery capacity highly
critical
alarm
appears, the
device will switch off in a few minutes’ time (less than 5 % capacity remaining). Keep
an alternative ventilation option to hand.
• If device and battery pack have been stored outside the quoted operating
temperatures, the device can only be started up once it has warmed up or cooled
down to the permitted operating temperature.
4.11.2 Charge battery
The battery is charged automatically as soon as the device is connected to the power
supply. The consecutively flashing segments of the battery indicator show the charging
process. Once the battery indicator is displaying 5 segments and is no longer flashing,
the battery is fully charged.
