external power source. The solid green portion represents the current charge level of the
batteries in proportion to its maximum charge level.
: indicates that external power source is not connected. The ventilator is powered
by built-in batteries. The solid blue portion represents the current charge level of the
batteries in proportion to its maximum charge level.
: indicates that external power source is not connected. The ventilator is powered
by built-in batteries. The battery capacity is low and the batteries need to be charged
immediately.

12.8.1 Battery Performance Conditioning
Condition batteries when they are put into use for the first time. A complete battery
conditioning cycle is: uninterrupted charging, followed by uninterrupted discharging until the
ventilator shuts off, and then uninterrupted charging. Condition batteries regularly to
maintain their service lives.
NOTE
Condition batteries every time when they have been used for three months or when
the battery running time becomes noticeably short.
Over time and with the use of the battery, the actual battery capacity will decrease.
For an old battery, the battery full icon does not indicate that the battery capacity
or battery running time still meets the requirement specified. When conditioning
batteries, replace the battery when its running time becomes noticeably short.
Follow these steps to condition batteries:
1. Disconnect the patient from the ventilator and shut down the ventilator.
2. Connect the ventilator to the external power source and charge the batteries
uninterruptedly for at least 10 hours.
3. Disconnect the external power source. Allow the ventilator to operate on battery power
until the ventilator shuts off.
4. Re-connect the ventilator to the external power source and charge the batteries
uninterruptedly for at least 10 hours.
5. Battery conditioning is now completed.
