id8/i10371/ 11/22/96 Page 2 IMPORTANT (In the United Kingdom) Mains Supply (AC 230 V z, 50 Hz only) RISK OF ELECTRIC SHOCK DO NOT OPEN DO NOT cut off the mains plug from this equipment. If the plug fitted is not suitable for the power points in your home or the cable is too short to reach a power point, then obtain an appropriate safety approved extension lead or consult your dealer.
id8/i10371/ 09/23/99 Page 3 INTRODUCTION CAUTIONS Thank you for purchasing a JVC product. Read this instruction book carefully before operating to be sure of getting optimum performance and longer service life from the unit. 1. Prevention of Electric Shocks, Fire Hazards and Damage 1) Even when the POWER switch is set to STANDBY, a very small current will flow. To save power and for safety when not using the unit for an extended period of time, disconnect the power cord from the household AC outlet.
id8/i10371/ 11/25/96 Page 4 2. Installation 1) Avoid placing the unit on or adjacent to an amplifier, to prevent hum from being produced by some types of amplifiers. Move the unit to a place not affected by the amplifier. Keep the unit as far as possible from a TV set. 2) Avoid installing the unit in a location subject to ambient temperatures exceeding 40 °C (104 °F) (e.g. direct sunlight, near heaters, etc.) or less than 0 °C (32 °F), excessive humidity, dust or vibrations.
id8/i10371/ 09/23/99 Page 5 CONNECTIONS • • • • Do not switch the power on until all the connections are completed. Insert the plugs firmly, or poor contact will result, causing noise. When the pin-plug cords are employed, always connect the white plug to the left channel terminal. This helps to avoid reversed connections. When using the Compu Link Control System version 3, do not connect the power cord to the SWITCHED AC OUTLET of an amplifier or receiver.

id8/i10371/ 09/23/99 Page 9 Dolby HX PRO headroom extension When a source which contains many high-frequency components is recorded, these high-frequency signals have the same function as bias and therefore, the effective bias current changes. This will result in phenomena such as changes in the level of low-frequency signal and subsequent distortion and reduction of the high-frequency saturation level.
id8/i10371/ 09/23/99 Page 10 Automatic Source Selection (COMPU LINK-1, 3) When the provided remote cables are used for connecting this unit to other components which have COMPU LINK-1 or 3/SYNCHRO terminals, the switch-over of all system components is possible with simple one-touch of the source selector button of JVC’s amplifier or receiver. By doing this, the corresponding component will start playing automatically.
id8/i10371/ 09/23/99 Page 11 Demagnetizing the heads Magnetic objects brought close to the head or using the deck for a long period of time, results in magnetization of the head, thus noise occurs. When the noise is excessive, high frequencies on the recorded tape may be erased. Demagnetize the heads and other metal parts that come into contact with the tape every 20–30 hours of use with a head demagnetizer (available from your audio store). Tape editing 1.
