6.3.3. Battery Self-test
The UPS performs a battery self-test every time it is turned on with the utility power
supply. The self-test is designed to determine any issue that may occur with the
battery power supply. If the battery status is normal, the UPS will continue to operate
in Normal Mode.
6.3.5. Alarm Mute
When the UPS is in Backup Mode, the alarm beeps once every 7 seconds. You can
mute the alarm tone manually by short pressing the power button. The alarm can’t be
muted when the battery is critically low.
6.3.6. Autorun
When the utility power is cut off the UPS will automatically switch to the Backup Mode,
during which the battery will supply the load. The switching time is between 2 and 6
milliseconds.
