STEP 1: Plug the AC input power cord of the DC UPS into the wall outlet (The

Self-test
Use the self-test to verify both the operation of the DC UPS and the condition
of the battery. Turn the mute switch ON then OFF, then ON and OFF again
within five seconds. During the Self-test, the DC UPS operates in backup
mode.
The DC UPS automatically conducts a Self-test in two conditions. 1) Operate
it and then the MCU detects battery voltage is higher than 13V. 2) Every 21
days while operating all the time.
Note: During the self-test, the DC UPS briefly operates on battery-backup
power. The green LED will flash for five minutes during the test period. If the
DC UPS passes the Self-test, it returns to online operation. If the DC UPS
fails the Self-test, it immediately returns to online operation and lights the red
LED. The loads are not affected. Recharge the battery overnight and perform
the self-test again. If the red LED is still on, the battery needs to be replaced.
