If the internal battery is discharged and the ex-
ternal power supply fails, the device cannot
ventilate.

battery is sufficiently charged.
CAUTION
Risk of self-discharge
Charge the internal battery if it has not been used
for some time. See "Charging the internal battery"
on page 115.

Incomplete charging and discharging cycles may
lead to an incorrect display of the charge state of
the internal battery. Improve the display accuracy,
see page 79.

ply or external battery), the device automatically
switches to the internal battery power supply. Ca-

tinued reliably for approx. 60 minutes without an
external power supply (with average ventilation val-
ues and normal ambient conditions).

than 30 %, the alarm message Int. battery low !!!
is displayed. At the end of the operating time, the
alarm message Int. battery empty !!! is displayed.
