Maintenance
Battery
The built-in battery must be charged after each use to ensure sufficient battery reserve.
Check battery performance
The battery life varies with the storage and using habit. The battery performance will degrade
gradually if the battery is not being used for a long time. To check its performance:
1) The battery icon shown on the screen should be normal.
2) The battery can be charged normally when connected to AC power supply.
3) Completely disconnect the monitor from the patient and stop all monitoring and measurement.
4) Ensure that the battery is charged uninterruptedly for at least 6h till it is fully charged.
5) Disconnect AC power supply, and use the battery to supply the monitor till the monitor shuts down
automatically; meanwhile record the duration time.
6) The discharging time reflects the performance of the battery.
7) When the discharging time reduces to less than 50% of the initial volume(10 hours), the battery is
thought to be poor performance and should be replaced with a new one.
