1) The system can’t start?
Usually this problem results from the incorrect power connection. Please follow below steps to
check the power connection:
1. Check the input power, whether the power wire is connected correctly, whether the ground wire is
connected back to the battery, and whether the fuse on the power wire is in good condition.
2. Check whether the ACC signal wire input to the power is with voltage higher than 7 V.
3. Check whether the device key is closed.
2) The MNVR restarts uninterruptedly?
Please follow below steps to check it:
1. Check whether the voltage of MNVR is insufficient. If the voltage is less than the start-up voltage of
the device, the device would always restart.
2. The problem in hard disk/SD card may cause the failure to start. Take off the storage part and check
whether it is broken down.
3) The device can’t record?

be read normally in computer.
2. Check whether the storage disk is formatted. The storage disk should be formatted before normally
storing record files.
