On-screen battery icon indicates the battery statuses as follows: 
  : indicates that external power source is connected. The ventilator is powered by 
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.
