HINT: Images may be unclear even in normal conditions if:
- Electrical devices are used in the cabin (noise may occur in the image).
- The camera lens is frosted over (the image immediately after turning the
power switch on (IG) may be blurred or darker than normal).
- The camera lens is dirty with snow, mud, etc.
- A strong beam of light, such as a sunbeam or headlight, hits the camera.
- It is too dark around the camera (at night, etc.).
- The ambient temperature around the camera is either too high or too low.
- The vehicle is tilted at a steep angle.
- The television camera assembly lens is scratched.
- The television camera assembly lens has drops of water on it or the humidity is high.
- When the camera is used under fluorescent lights, sodium lights, or
mercury lights, etc., the lights and the illuminated area may appear to
flicker.
