Minor Alarms
- When a minor alarm is generated, the LCD automatically turns on the backlight and the buzzer sounds twice every 3s.
- If there is an alarm, press ON/MUTE for more than 2s in non-setting mode to mute the current alarm. When the UPS generates a new alarm, the mute function becomes ineffective. If you need to mute the alarm, perform the mute operation again.
