TROUBLESHOOTING

No Display
1. Check the fuse (FU500) on the digital PCB.
2. Check the fuse (FU100) on the linear PCB.
3. Check the jack (JK500) on the digital PCB.
4. Check the power switch (SW900) on the key PCB.
5. Check the flat cable between the digital and linear PCBs.
6. Check the back light.
7. Check the LCD.
No Display at Record Mode
1. Check the camera unit.
Defect of the Camera Unit
The camera unit must be replaced with whole unit when it is defective, because the precise adjustment is required when the individual parts of the camera unit are replaced, and it can be done only at our factory. (Except for replacing the outer case of the camera unit)

DISASSEMBLY

To disassemble the main unit
1. Rotate the camera unit then remove the two screws on the side of the unit.
2. Remove the two screws on the bottom of the unit and the battery cover. Then remove the upper case at the bottom of the unit.
3. Then remove the upper case at the top of the unit.
4. Be careful not to lose the switch knob.
