FORD 2004 E-450 v.1 - Manual (Page 30)

Dew sensor circuit
• Under high moisture (dewed) conditions, the tape heads and cassette
tape may be damaged if the VCP is operated.
• When the vehicle’s cabin temperature is very low and then is heated
quickly, or the humidity is very high within the vehicle, the inside of
the windows most likely will be fogged. Under these conditions, the
inside of the VCP most likely is dewed.
• When a dewed condition exists, the dew sensor circuit stops machine
operation, ejects the cassette and the WAIT indicator illuminates. The
lamp will remain illuminated until the system is dry enough to operate
safely.
Cleaning video heads
Magnetic video heads convert the videocassette into pictures on the
screen during playback. Over a period of time, particles rub off the tape
and are left on the heads. Using an old or poor quality tape together with
dust and air particles, high temperature and humidity cause dirty heads.
Dirty heads generally cause “snowy” pictures and, in some severe cases,
blurred or interrupted pictures. It is suggested that the heads be cleaned
after every 10–15 hours of use. A variety of products are available to
clean tape heads. Use these products sparingly, and ensure that you use
products which are labeled as “non-abrasive”. If normal head cleaning
procedures do not resolve the problem, have the system checked by a
service technician.
Foreign substances
Exercise care to prevent dirt and foreign objects from entering the VCP
compartment. Be especially careful not to spill liquids of any kind onto
the media controls or into the videocassette player. If liquid is
accidentally spilled onto the system, immediately turn the system OFF
and consult a qualified service technician.
