 ： indicates that AC power source is not connected. The ventilator is powered by
built-in batteries. The battery capacity is a bit low and the batteries need to be charged
immediately.

：
indicates that no batteries are installed.
The capacity of the internal battery is limited. If the battery capacity is too low, power supply
failure will occur and a high-level alarm [
Low Battery Voltage! ] will be triggered. In this
case, apply AC power to the ventilator.
11.8.1 Battery Use Guidance
Inspect and replace batteries regularly. Battery life depends on how frequent and how long it
is used. For a properly maintained and stored lithium battery, its life expectancy is
approximately 3 years. For more aggressive use models, life expectancy can be shortened.
We recommend replacing lithium batteries every 3 years.
To ensure maximum battery capacity:
 Check battery performance once every six months. Checking battery performance is also
required before ventilator repair is carried out or when battery is doubted to be the
source for ventilator failure.
 Condition batteries once every time when they have been used for three months or when
the battery running time becomes noticeably shorter.
