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 temperature range of 0°C to 40°C and a relative humidity of 30% to 80%. Using this device 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 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 equipment. • 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 (especially 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 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 this device 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 this device against a hard object. • Remove the videocassette before transporting this device. 6 • 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 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. 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 manufactured 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. However, 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 temporarily 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 damage 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.
