  If the LCD is blinking and the buzzer beeps twice every second, it indicates that the UPS is overloaded. Here's what you should do: * Remove surplus load from the UPS output end. In some instances, the UPS might be overloaded multiple times in quick succession, causing it to lock in bypass mode. If this happens, remove the extra load, then shut down and restart the UPS.

  If the battery backup time of your Huawei UPS is shorter than expected, it could be due to a couple of reasons. First, the batteries may not be fully charged.
