JVC GY-DV301, GY-DV300 instruction manual Precautions for Proper Use, Supply voltage

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.

●Optical performance of lens

Due to the optical performance of the lens, colour 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.

●Do not set the POWER switch to OFF or remove the power cord during recording or playback. Otherwise the tape may be damaged.
