- Checking the battery status
To switch the unit on, press and hold the Power/Test button for approximately 5 seconds and then release the button.
To switch the unit off, press and hold the Power/Test button for approximately 3 seconds and then release the button.
If DC input for BMU801 is disabled, for example, in case of a power outage, BMU801 returns to the state in which it was before the outage when DC power is available again.
