recommends that the ventilator is not operated without a
battery or with low batteries (capacity < 10%) because the device will switch off
immediately in the event of a power failure.
CAUTION
Failure to comply can cause total discharge of the batteries so that they no longer
function. Failure to comply with this safety instruction is considered to be an
operating error on the part of the user.
CAUTION
If the battery is completely discharged, recharging may no longer be possible and
replacement may be required. The internal battery (battery 1) may only be replaced by

customer service team.
The primary supply of the ventilator is mains voltage. In case of a power
failure or if the device is disconnected from the external voltage source
(e.g. during patient transport), energy is supplied by the internal voltage
source. This is indicated by a text message in the alarm field.
The device is equipped with an internal battery with a battery life of
3 hours. An external battery may be used (optional); it extends the run
time by an additional three hours. The type of energy supply is indicated
both on the monitor (see chapter 3.2.6) and on the housing
(see chapter 3.1.2).
NOTE
The specified run time assumes a new battery with a capacity of 100%. The operating
time can be affected by the age of the battery, the charging cycles, and the charge
level and can therefore deviate from specifications.
