INTRODUCTION Precautions for Proper Use ● Supply voltage Make sure that the power is between 6 V and 12 V DC. If the power voltage is too low, abnormal colour and increased noise may occur. Do not exceed 12 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. When storing the GY-DV300 for a long time, the storage temperatures should be -20°C to 60°C. ● Strong electromagnetic waves or magnetism Noise may appear in the picture or audio and/or the colours may be incorrect if the camera is used near a radio or television transmitting antenna, in places where strong electromagnetic waves are generated by transformers, motors, etc., or near devices emitting radio waves, such as transceivers or cellular phones. ● If a transceiver or cellular telephone is used closed to the GY-DV300 while the camera-shake compensation function is in use, the camera image may flicker due to the influence of emitted electromagnetic waves. ● 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. ● 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 not provided with a setup level when shipped from the factory. If you want to turn ON the setup level, please set the SET UP item on the SYSTEM menu screen to ON. ● 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. ● Use the unit in an upright position. If placed on its side, heat release efficiency will deteriorate, adversely affecting the tape transport. Depending on the circumstances, the tape may also be damaged. ● Vibrations Colours may fail to appear during VCR playback in locations subjected to 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 other objects 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. 7

Precautions for Proper Use
●
Supply voltage
Make sure that the power is between 6 V and 12 V DC. If the power voltage is too low, abnormal colour
and increased noise may occur. Do not exceed 12 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. When storing the GY-DV300 for a long time, the storage temperatures should be
–
20
°
C to
60
°
C.
●
Strong electromagnetic waves or magnetism
Noise may appear in the picture or audio and/or the colours may be incorrect if the camera is used near
a radio or television transmitting antenna, in places where strong electromagnetic waves are generated
by transformers, motors, etc., or near devices emitting radio waves, such as transceivers or cellular
phones.
●
If a transceiver or cellular telephone is used closed to the GY-DV300 while the camera-shake
compensation function is in use, the camera image may flicker due to the influence of emitted
electromagnetic waves.
●
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.
●
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 not provided with a setup level when shipped from the
factory. If you want to turn ON the setup level, please set the SET UP item on the SYSTEM menu
screen to ON.
●
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.
●
Use the unit in an upright position.
If placed on its side, heat release efficiency will deteriorate, adversely affecting the tape transport.
Depending on the circumstances, the tape may also be damaged.
