Notes on Use
Notes on Use
Notes on the Videocassette
Recorder
Do not use the unit in a place subject to direct
sunlight or heat sources
If you do, its cabinet, mechanical parts, etc., may be
damaged.
Do not use the unit in an extremely hot place
If the unit is left in a car parked with the windows
closed (especially in summer), its cabinet, mechanical
parts, etc., may be damaged or it may not work
correctly.
If the unit is brought directly from a cold to a
warm location
Moisture may condense inside the unit and cause
damage to the video heads and tape. If you use the unit
in a place subject to direct cold currents from an air
conditioner, moisture may also condense inside the
unit.
Do not place a heavy object on the unit
The cabinet, mechanical parts, etc., may be damaged,
or the unit may not work correctly.
Do not handle the unit roughly
Avoid rough handling or mechanical shock to the unit.
To avoid damaging the cabinet’s finish
Plastic is often used for the surface finishing of the
unit. Do not spray a volatile solvent such as an
insecticide toward the cabinet or place rubber or vinyl
products on the cabinet for a long time. If you do, the
finish of the cabinet may be damaged or the coating
may come off.
Do not clean the cabinet with thinner or
benzine
The cabinet may be damaged or its coating may come
off. When you use a chemical-impregnated cloth, use
it according to its directions.
Clean the cabinet with a soft dry cloth
When the cabinet is very dirty, clean it with a soft dry
cloth lightly moistened with a mild detergent solution
and finish it with a dry cloth.
Do not put magnetic objects close to the unit
Magnetic fields may damage the recording.
To prevent electromagnetic interference
caused by radio communication equipment
such as cellular phones, transceivers, etc.
The use of the radio communication equipment such as
cellular phones or transceivers near the unit may cause
a malfunction and can affect the audio/video signals.
Cellular phones or transceivers near the unit should be
switched off.
Do not use the unit in an area exposed to
radiation
A malfunction may occur.
Checking the video heads every 1 000 hours
A VCR is a high-precision piece of equipment that
records and plays back the picture recorded on a
magnetic tape. In particular, the video heads and other
mechanical parts may become dirty or worn. To
maintain a clean picture, we recommend maintenance
every 1 000 hours, even though the conditions of use
may differ depending on temperature, humidity, dust,
etc.
When you transport the unit
Be sure to transport the unit carefully. Do not use the
supplied carton and packing materials repeatedly. They
are made from corrugated cardboard, and are designed
to protect the unit only one time, when the unit is
purchased and delivered to you.
Cleaning of the Video Heads
With clogged video heads, the unit cannot record
properly. Clean the video heads to prevent noise on the
recorded picture or audio. For cleaning, use the
supplied cleaning cassette.
Before recording an important event
The unit cannot record properly with the clogged video
heads. To ensure normal recording and clear pictures
and sound, clean the video heads before recording an
important event.
Every 50 hours
If you repeat the tape transport operation, the video
heads will become dirty and coated with fine dirt or
dust. Clean the heads every 50 hours.

After using a tape prone to clog the heads
After using such a tape causes the symptoms
illustrated below, clean the heads.
When the symptoms caused by clogged video
heads appear
Even if you clean the heads periodically, clogging of
the heads may occur anyway. Clean the heads when:
• mosaic-pattern noise appears on the playback picture.
• a part of the playback picture does not move.
• playback pictures do not appear.
• playback audio is interrupted.
To use the cleaning cassette
Refer to your cleaning cassette’s instruction manual.
Cleaning cassettes are replaceable. The number of
times you can use the cassette is specified in the
cassette’s instruction manual. After using the cassette
that number of times, buy an optional DVCAM
cleaning cassette or a Sony Digital Video Cleaning
Cassette.
After prolonged use, the video heads may become
worn out. If optimum picture quality is not restored
even after you have cleaned the video heads with the
cleaning cassette, the video heads may have worn out.
In that case, you have to replace the video heads with
new ones. Please consult your Sony dealer.
Notes on the Video Cassettes
If the cassette memory function does not work
Reinsert the cassette a few times. The terminal portion
of the cassette may be dusty or dirty.
Cleaning the terminal
If the terminal of the cassette gets dirty, or dust sticks
to the terminal, the unit may not work correctly.
Clean the terminal with a swab once every ten times
you eject a cassette.
When affixing a label to the cassette
Be sure to affix a label only on the correct location so
as not to cause malfunction of the unit.
After using a cassette
After use, please be sure to rewind the tape completely
(to prevent picture and sound distortion). Return it to
its case and store it in an upright position.
Notes on the LCD Screen
The LCD screen is manufactured using high-precision
technology. The ratio of effective pixels is 99.99% or
more. However, there may be some tiny black points
and/or bright points (red, blue, green or white) that
constantly appear on the LCD screen. These points do
not affect the recorded picture in any way.
Do not place this unit with the LCD screen pointing
toward the sun. Otherwise, the unit may be damaged.
The backlight used in the built-in LCD monitor
deteriorates with prolonged use. If the brightness of
the LCD monitor cannot be adjusted, consult your
Sony dealer.
To clean the LCD screen
To remove dirt or to clean fingerprints from the LCD
screen, use an LCD cleaning kit (not supplied).
About Moisture Condensation
If the unit or cassette is brought directly from a cold to
a warm location, moisture may condense inside or
outside the unit or tape. If you use the tape or video
heads in this condition, the tape may adhere to the
head drum, and the video heads or the tape may be
damaged, or a malfunction may occur.

Notes on Use
Moisture condensation is likely to occur under the
following conditions:
• The unit or cassette is brought from the cold outdoors
to a warm indoor location.
• The unit or cassette is brought from the air-
conditioned indoors to the hot outdoors.
• The unit is used in a place subject to cold currents
from an air conditioner.
When bringing the unit or cassette from a cold place to
a warm place or vice versa, put it in a plastic bag and
seal the bag tightly. After bringing it into the new
place, leave the bag on for more than one hour, and
remove the bag when the air temperature inside it has
reached the temperature surrounding it.
If moisture condensation occurred
You cannot operate the unit except to press EJECT,
and a cassette cannot be inserted. If this occurs, with
the unit powered on, remove the cassette, then wait
more than one hour for the moisture to evaporate.
Digital Hours Meter
The digital hours meter keeps cumulative counts of the
total operation time, the head drum rotation time, the
tape running time and the number of unthreading
operations. These counts can be displayed on the
menu. Use them as guidelines for scheduling
maintenance.
In general, consult your Sony dealer about necessary
periodic maintenance checks.
The digital hours meter has the following four display
modes and you can check them in HRS METER of the
OTHERS menu (See page 92 (GB)).
•
OPERATION mode
The cumulative total hours of operating time is
displayed in 10-hour increments.
• DRUM RUN mode
The cumulative total hours of drum rotation with tape
threaded is displayed in 10-hour increments.
• TAPE RUN mode
The cumulative total hours of tape running time is
displayed in 10-hour increments.
•
THREADING mode
The cumulative number of tape unthreading
operations is displayed in 10-operation increments.
Self-diagnostics Function
The unit has a self-diagnostics display function.
This function displays the current condition of the unit
as a five-digit code (a combination of a letter and
numbers), on the LCD monitor, display window, and
MONITOR VIDEO output. If a five-digit code is
displayed, check the following code chart. The last two
digits (indicated by
ss ) will differ depending on the
state of your unit.
If you are unable to resolve the problem, or a code
other than those in the above chart appears, contact
your Sony dealer or local authorized Sony service
facility and inform them of the number.
