Troubleshooting
Check the following guide for the possible cause of a problem before contacting service.
• The picture is poor
Does the Dome Cover have lots of dust on the surface?
- Use a dry cloth to clean the camera when it is dirty.
Smear may be caused to the screen of night than daytime.
- Adjust the Focus by moving the Focus Lens.
• Contrast of the screen is not clear.
Check the condition of the monitor.
Alight source such as a spot light causes burn-in on the display screen. Adjust position or angle of the
camera to eliminate strong background light.
• Line-Lock mode cannot be active
- Line-Lock mode cannot be active with DC 12V power source so use AC 24V power source.
- Set the Line-Lock switch to the Line-Lock (OFF) mode. (Refer to page 12.)
- If screen conversion of the cameras cannot be become softly, adjust the line-lock vertical phase
using VR702 (Variable Register).
