INTRODUCTION
Precautions for Proper
Use
• Supply voltage
Make sure that the power is between 11 V and 15 V DC. If
the power voltage is too low, abnormal color and
increased noise may occur.
• Allowable ambient temperature and humidity
Be sure to use this device within the allowable tempera-
ture range of 0°C to 40°C and a relative humidity of 30% to
80%. Using this device at a temperature or humidity out-
side the allowable ranges could result not only in malfunc-
tion but the impact on the CCD elements could be serious
as small white spots may be generated.
• Strong electromagnetic waves or magnetism
Noise may appear in the picture or audio and/or the colors
may be incorrect if the camera is used near a radio or tele-
vision transmitting antenna, in places where strong mag-
netic fields are generated by transformers, motors, etc., or
near devices emitting radio waves, such as transceivers or
cellular phones.
• Use of wireless microphone near the camera
When a wireless microphone or wireless microphone
tuner is used near the camera during recording, the tuner
could pick up noise.
• Avoid using or placing this device in places;
• subject to extreme heat or cold;
• with excessive dirt or dust;
• with high humidity or moisture;
• subject to smoke or vapour such as near a cooking
stove;
• subject to strong vibrations or on an unstable surface;
• also do not leave this device for long hours in a parked
car under direct sunlight or near room heating equip-
ment.
• Do not leave this device where it is subject to radiation or
X-rays or where corrosive gasses occur.
• Protect this device from being splashed with water (espe-
cially when shooting in the rain).
• Protect this device from being wet when shooting on a
beach.
In addition, salt and sand may adhere to the camera body.
Be sure to clean the camera after use.
• Protect this device against penetration of dust when using
it in a place subject to sandy dust.
• Optical performance of lens
Due to the optical performance of the lens, color diver-
gence phenomena (magnification chromatic aberration)
may occur at the periphery of the image.
This is not a camera malfunction.
• Noise may appear in the viewfinder when switching
between the playback picture and the EE picture.
• Use this device in an upright position.
If placed on its side, heat release efficiency will deterio-
rate, adversely affecting the tape transport. Depending on
circumstances the tape may also be damaged.
• Vibrations
Colors may fail to appear and/or the image and sound
may be disturbed during VTR playback in locations sub-
jected to strong vibrations.
• Precautions for transportation
Do not drop or hit this device against a hard object.
• Remove the videocassette before transporting this device.
• Do not insert an object other than a videocassette in the
cassette insertion slot. Be sure to close the cassette cover
when this device is not to be used for a long period.
• Do not set the POWER switch to OFF or remove the
power cable during recording or playback. Otherwise the
tape may be damaged.
• The sensitivity level of the provided microphone is set
lower than the reference input (–60 dBs) setting.
• When this device is not in use, be sure to set the POWER
switch to OFF in order to reduce power consumption.
• Cleaning the body: Wipe body with a dry, soft cloth. To
prevent deformation of the body, etc. and to avoid opera-
tion hazards, do not allow volatile liquids such as benzine
and thinner to touch the body, and do not wipe it with a
cloth soaked in such a liquid. When it is extremely dirty,
soak the cloth in a solution of neutral detergent, wipe the
body with it, and then use a clean cloth to remove the
detergent.
• The camera may not show stable pictures in the period
immediately after the power is turned on, but this is not a
malfunction.
• A sound occurs when the built-in head cleaner that runs
when you load or eject a videocassette operates, but this
is not a malfunction.
• The LCD monitor and the viewfinder screen
The LCD monitor and the viewfinder screen are manufac-
tured using high-precision technology. Black spots may
appear on the LCD monitor and the viewfinder screen, or
red, blue, green and/or white spots may not turn off. How-
ever, this is not a malfunction and these spots are not
recorded on the tape.
• If you use this device continuously for a long period of
time, the characters displayed in the viewfinder may tem-
porarily remain on the screen. This is not recorded on the
tape. In addition, they are no longer displayed if you turn
the power off and then on again.
• If you use this device in a cold location, the images may
appear to lag on the screen, but this is not a malfunction.
This is not recorded on the tape.
• Do not insert fingers or foreign objects into the cassette
insertion slot as this may result in personal injury or dam-
age to the mechanism.
• To prevent damage to the connectors, use this device with
the connector covers on when you are not using the video/
audio signal output connectors.
CAUTION
• Do not point the lens or viewfinder directly at the sun or
other strong light source.
• Eye damage could result.
• If the lens or viewfinder is left pointed at the sun, rays
may collect inside this device and cause damage or a
fire.
• When carrying the camera, be sure to hold the carrying
handle. Holding the lens or viewfinder may result in
damage.

Routine and Periodical
Maintenance
This device incorporates precision mechanical parts, which
will collect dirt, wear out and deteriorate as this device is
used. After this device has been used for a long period even
in a normal environment, the heads, drums and tape trans-
port mechanisms also collect dirt. Especially, dust which
penetrates the inside of the VTR section during outdoor use
will promote the wear and deterioration of mechanical parts
by causing poor contact between tape and heads or failing to
maintain the video and audio quality at high levels. To pre-
vent wear and deterioration, clean the mechanical parts
using a head cleaning tape as routine maintenance. How-
ever, cleaning with a head cleaning tape alone is not enough
for cleaning the entire tape transport mechanism, so it is also
recommended to apply periodical maintenance (inspection)
to prevent the sudden occurrence of failure. As the replace-
ment, adjustment and servicing of parts require advanced
skill and equipment, please consult the person in charge of
professional video equipment at your nearest JVC-autho-
rized service agent.
Head Cleaning
• To maintain beautiful pictures and sound, be sure to use a
head cleaning tape to clean the head periodically.
X
See “Precautions for Use of Head Cleaning Tape”. If
head cleaning is not performed periodically, a type of
mosaic noise called block noise may appear in the picture
or sound may be interrupted.
• Please use cleaning tape produced by JVC. Do not use
head cleaning tapes other than specified.
X
See “Precautions for Use of Head Cleaning Tape”
about how to use the head cleaning tape and precautions
for use of the head cleaning tape.
• When dust adheres to the heads, the warning message
“HEAD CLEANING REQUIRED!” is displayed on the LCD
monitor, and in the viewfinder during playback and record-
ing check using the RET button on the lens section.

enters the STOP mode.)
2.
Do not use the tape more than four times at the most for
each cleaning.
Use the following chart as a guide for periodical head
cleaning.
Note 1)
When used in a low humidity environment, head
cleaning should be conducted at intervals half of
those given in the chart above.
Note 2)
If an M-DV80 tape is used immediately after head
cleaning, the “HEAD CLEANING REQUIRED!”
indicator may remain on. In this case, let the tape
run as the indicator will turn off after the tape has
run for a while.
Note 3)
Use the cleaning tape in the room temperature
(10°C to 35°C).
Note 4)
The cleaning tape case contains instructions for
use of the cleaning tape. However, some of these
instructions differ from the contents of this sheet.
When using the cleaning tape, please follow the
instructions of this sheet.
Note 5)
If the “HEAD CLEANING REQUIRED!” does not
disappear after repeated head cleanings, the
recording tape may be abnormal. Avoid excessive
repeated use of the head cleaning tape.
