Auto self-test Function:
In normal mode of UPS, turn on your computer and push the button on the front panel
for self-test. The UPS will simulate a power outage and transfer your load to the
UPS battery. If low battery warning sounds during the test, it means that the battery
set is weak and requires extended recharge. If battery NG warning sounds, it means
that the battery set is damaged and requires replacement.
