Troubleshooting

Troubleshooting
1. Since the problem in this unit involves a security issue, you should replace the entire
unit when encountering a problem.
2. If a problem is confirmed, turn off the power, remove the power cable and bracket,
and then replace the unit with a new one. For the assembly of the unit, follow the
reverse order.
3. If LED1 is off, check the cable connection to see if the power supply is okay.
4. If LED1 is on and LED2 is off, it means EPP is in abnormal operation. Therefore,
replace the EPP.
