CLEANING
• Gently wipe your screen with a clean camel hair brush or a soft, clean, lint-free cloth.

• Chemical cleaners can damage the screen or the LCD monitor casing.
Troubleshooting
Intermittent Loss of Video in PIP/PBP and Main Video
Possible cause: In PAL, when using PIP or PBP, cycling through cameras (with one or more cameras out of operation) causes the monitor to
auto adjust and locate the signal.
Remedy: Check your input devices. If there is a problem with a camera from another input device such as no power signal or bad video, then
correct or disconnect the camera or device.
WARNING: To reduce the risk of electrical shock, do not remove the cover or back of the monitor. No user-serviceable parts are inside.
