4. NOTES FOR REAR TELEVISION CAMERA ASSEMBLY

(a) Notes for the rear television camera assembly

(1) The rear view monitor system may not function properly if subjected to a severe blow by any hard object.

(2) Do not scrub the cover part of the camera (resin made). Scrubbing may scratch the cover and affect the image. Prevent organic solvents, waxes, bond removing solvents or glass coating from adhering to the cover. If such material adheres to the cover, clean it off immediately and wash it with water.

(3) Exposing the camera to a sudden temperature change may affect proper functioning of the camera.

(4) A clear image may not appear if the camera is dirty with snow, mud, etc. In that case, wash it with water and wipe off the lens. Use a detergent to remove dirt if necessary.

(b) Images may be unclear even in normal conditions if:

(1) The camera lens is frosted over (the image immediately after turning the ignition switch to ON may be blurred or darker than normal).

(2) A strong beam of light, such as a sunbeam or headlight, hits the camera.

(3) It is too dark around the camera (at night, etc.).

(4) The ambient temperature around the camera is either too high or too low.
