Maintenance
Camera
If dirt, rain, or snow attaches to the camera, the monitor may not clearly display objects. If water droplets, snow, or mud adhere to the cam-
era lens, rinse with water and wipe with a dry cloth.
Do not use alcohol, benzene, or thinner to clear the camera. This will cause discoloration. To clean the camera, wipe with a clean cloth
dampened with mild cleaner diluted with water and then wipe with a dry cloth.
Monitor
Turn off the monitor. If the screen is dark, it will be easier to see the areas that are dirty or oily.
Use a dry, soft cloth and very gently wipe the screen.
If the dry cloth did not completely remove the dirt or oil, do not press harder in an attempt to scrub it off. Pushing directly on the LCD screen
can often cause pixels to burn out.
If necessary, dampen the cloth with distilled water or with an equal ratio of distilled water to white vinegar. The plastic edge that surrounds the
screen can be cleaned with any multipurpose cleaner but take care to avoid contact with the screen itself.
Avoid using paper towels, toilet paper, tissue paper, or something like your shirt to wipe the LCD screen. These non-ultrasoft materials can
easily scratch the screen.
Avoid cleaning products that contain ammonia, ethyl alcohol, acetone, toluene, ethyl acid, or methyl chloride. These chemicals can react with
the materials that the LCD screen is made of which could yellow the screen or cause other kinds of damage.
Never spray liquid directly on the LCD screen or it could run inside the monitor and cause damage.
