7 Troubleshooting

Please refer to the troubleshooting methods mentioned below. Please read the "Table 7-1 LED indica-
tion" of this manual before troubleshooting to avoid false operations.
For example, the blinking or constant red light of the ALM alarm on the front panel does not necessarily
indicate a faulty battery. In most cases, the "alarm" indication signifies normal operation and requires no
troubleshooting. Furthermore, if the battery indicates "protection," it will resume normal operation
automatically once the "protection" status is released.
