1. INTRODUCTION

1-1 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. Do not exceed 15 V DC in any case, or the
unit could be damaged.
● Allowable ambient temperature and humidity
Be sure to use the unit within the allowable temperature range
of 0°C to 40°C and a relative humidity of 30% to 80%. Using
the unit at a temperature or humidity outside the allowable
ranges could result not only in malfunction 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
television transmitting antenna, in places where strong
magnetic 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 the unit 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 the unit for long hours in a parked car
under direct sunlight or near room heating equipment.
● Do not leave the unit where it is subject to radiation or x-
rays or where corrosive gasses occur.
● Protect the unit from being splashed with water
(especially when shooting in the rain).
● Protect the unit 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 the unit against penetration of dust when using it in a
place subject to sandy dust.
● Setup level
The video signal of the unit's video output is provided with a
setup level when shipped from the factory. If you want to turn
OFF the setup level, set the SET UP item on the AUDIO/
VIDEO menu screen to 0.0%.
● Optical performance of lens
Due to the optical performance of the lens, color divergence
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 the unit in an upright position.
If placed on its side, heat release efficiency will deteriorate,
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 subjected to
strong vibrations.

● Precautions for transportation
Do not drop or hit the unit against a hard object.
● Remove the videocassette before transporting the unit.
● Do not insert an object other than a videocassette in the
cassette insertion slot. Be sure to close the cassette cover
when the unit 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 the unit 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. 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. To prevent deformation of the body,
etc. and to avoid operation 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.
● The camera may not show stable pictures in the period
immediately after the power is turned on, but this is not a
malfunction.
● If a tape containing recorded PAL signals is played back,
"PAL INHIBIT" is displayed and correct playback will not take
place. If this happens, remove the videocassette so that the
unit returns to its normal state.
● When turning on the power with the tape inserted or after
loading a tape, the built-in head cleaner will emit a sound
while operating. However, this is not a malfunction of the unit.
● The LCD screen and the viewfinder screen are manufactured
using high-precision technology. Black spots may appear on
the LCD screen and the viewfinder screen, or red, blue, green
and/or white spots may not turn off. However, this is not a
malfunction and these spots are 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 damage
to the mechanism.
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 the unit 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.
