3-4. MAINTENANCE PROCEDURES
3-4-1. REGULAR MAINTENANCE
The purpose
of
periodic maintenance
is
to
preserve
the functioning
of
this
machine
throughout
its
useful life. The user
or
service dealer should
perform
these maintenance
regularly
to
ensure
that
maximum
utility
is
obtained
from
the machine.
The VCR is a complicated place
of
equipment.
It
contains many belts, rollers, heads etc., which
become worn, and deteriorate
as
time goes by,
causing trouble. Dust and
dirt
will also impede the
proper
functioning
of
the machine. In light
of
this,
it
is
very
important
that
overall maintenance
be
done according
to
the maintenance
chart
to
maintain
the functions
of
the VCR, and
to
avoid
accidental problems. This maintenance should also
be
performed
after
any repairs are done
on
the
equipment.
3-4-2. MAINTENANCE CHART
The
following
periodic maintenance is required
to
prolong
the life
of

The VCR
used
for
business applications requires
particular
attention
for
several reasons. The
installation conditions and applications are
not
always the best. Long
use
times,
or
poor
environmental conditions may adversely affect the
lifespan and performance
of
the machine. Regular
maintenance assures
that
the purchaser obtains
the maximum value
for
his expenditure.
Accordingly, the necessity
of
regular maintenance
should
be
fully
explained
at
the time
of
sale,
as
well
as
during
after-sale repairs.
