Routine maintenance for
longterm, trouble-free
operation
Keep the video head clean
the video head will become dirty with extend-
ed use. If recording is continued when the
head
becomes dirty,
picture
noise and
dropouts will
occur.
The Betamovie incorporates a special lamp to
alert you when the head is dirty.
When the REC START/STOP button is
pressed and recording begins, the "C" or
CAUTION lamp flashes.
This indicates that the head is dirty or clog·
ged.
Press the REC START/STOP button
repeat·
edly, alternatively starting and stopping
recording. If the indicator stops flashing,
recording can be resumed.
If the indicator does not stop flashing, do
the
following.
Stop recording and clean the head.
For best results, use the optional L·25CL
cleaning tape.
• Incorrect use of the cleaning tape can
cause damage to the video
head.
To
pre-
vent this, read the cleaning tape instruction
manual carefully before using.
• If the indicator light continues flashing
after the head is cleaned
,
contact the
outlet where the Betamovie was purchased
or your nearest authorized Sony service
facility.
• If picture quality is not sharp after the head
has been cleaned
,
it is possible that the
head is worn
.
In this
case,
the video head
will have to be replaced.
Cleaning the lens
If
the lens surface becomes dusty or
dirty,
pic-
ture quality will
not
only
suffer,
but the auto
focusing system may also work
improperly,
resu lting in out-of-focus scenes.
Periodic inspection
Because the image is recorded from the
Betamovie onto magnetic
tape,
high prec ision
is required
for
opt
imum
recording quality.
Especially,
the video head and tape transport
mechanism wil
l
become dirty and wear with
extended use. To ensure optimum recording
quality,
it is recommended that basic inspec-
tion and repairs be conducted after every
1,000 hours of
operat
ion
.
These include c lean-
ing
, lubricating,
and replacement of worn
parts.
When the Betamovie will not be used for a
long period of time
• Remove the
cassette.
If the cassette is left
in the
camera,
the tape may stick to the
head or other parts may be damaged.
• Operate the Betamovie for a few minutes at
least once
every six months,
using
t
he
zoom and focu
s rin
gs and other
functions.
This prevents deterioration of the Trin icon
tube and other internal parts through
d isuse.
For additional information on inspection,
head
changing,
and other maintenance
procedures, contact your nearest Sony
dealer or authorized Sony service facility.
