Maintenance inspections are necessary for the user to use
the video equipment safely and to keep the function in good
condition at all times through periodical and appropriate main-
tenance.
In order to make the most of the function of this unit, be sure
to carry out the maintenance inspections.
1. Necessity of periodical maintenance services
Backlight as a light source and heat exhaust fan motor are
used for the liquid crystal monitor.
These parts (consumable) are deteriorated with lapse of

eration of trouble.
Accordingly, besides the conventional after-services per-
formed in case of trouble, it is very important to perform
general services, that is, maintenance services in order to
prevent accidents or trouble due to deterioration of con-
sumable parts, keeping the equipment in normal condition.

The following maintenance execution time is set as a stan-
dard and not identical with individual life time. Also, note
that the deterioration time varies with the using environ-
ment and method.

sult with your dealer.
