Panasonic Hi-Fi Professional/Industrial Video DS850 - Manuel (Page 66)

Regular inspections

Head cleaning
If the screen should appear as shown below, it means that the video heads are dirty. Use the optional cleaning tape
(NV-TCLA) to clean the heads. Consult with your dealer if the symptoms should persist even after cleaning.
Repeated head cleaning will shorten the service life of the video heads.
Nothing can be recorded on the head cleaning tape.
Maintenance
Before proceeding with maintenance, set the power switch to OFF and, remembering to take hold of the power plug,
disconnect it from the power outlet.
Use a soft cloth to clean the cabinet. With stubborn stains or dirt, dilute some dish washing liquid, allow a cloth to soak
in it, and then wring it out and clean. After having removed the stains or dirt, use a dry cloth to wipe away any
moisture.
Do not use paint thinners or benzine.
Storage
Avoid storing the unit in a location where the temperature is by extremely high or low.
Under no circumstances should the unit be left outdoors.
If there are no plans to use the unit for a prolonged period of time, set the power switch to OFF and, remembering
to take hold of the power plug itself, disconnect it from the power outlet. This is done to safeguard against accidents
and breakdowns.
Before storing, always remember to remove the cassette tape if one is still inside the unit.
