1 INTRODUCTION 1-2 Periodical Maintenance This VCR incorporates precision mechanical parts which will collect dirt over time and ultimately deteriorate and wear out. Over long periods of use, dirt and dust accumulates on the heads, drums and tape transport mechanisms. Dust which penetrates the VCR (especially during outdoor use) also promotes the wear and deterioration of mechanical parts by causing poor contact between tape and heads. This also prevents the VCR from maintaining video and audio quality at high levels. To prevent wear and deterioration, clean the heads regularly using a head cleaning tape. However, because a head cleaning tape alone cannot clean the entire tape transport mechanism, this should also be inspected periodically to prevent any problems that could result from a sudden failure. As replacement and adjustment of parts require advanced skills and specialized equipment, please contact the person in charge of professional video equipment at your nearest JVC-authorized service agent for servicing. Monitoring Usage Time The total operation time reached by an ordinary home VCR in 5 or 6 years may be reached by a professional VCR in as few as 5 or 6 months. Therefore, it is important that the total hours of operation be carefully monitored. An hour meter in the on-screen display (see page 20) shows the accumulated time. In the chart below, the hours accumulated in each month are shown in relation to the number of hours used per day. Times shown in the shaded area indicate that maintenance should be performed.

The information above should be used as a reference guide. Replace the built-in lithium battery approximately every two years. 1-3 Precautions Handling and storage place 5 Avoid using the unit in places subject to the following conditions: • extreme heat or cold • strong magnetic fields (do not use a transceiver within 2 meters of this unit) • high humidity • dust and soil • vibrations • variations in temperature 5 Use this unit in horizontal (flat position) only. 5 To avoid overheating the unit, do not block ventilation slots or stack the units. If the internal temperature rises too high, the tape may be damaged. 5 Do not leave the unit in the Still or Record Pause mode for a long time as this may damage the tape. After about 3 minutes, this unit automatically enters the Stop mode. 5 Handle the unit carefully • Do not place anything heavy on the unit (a monitor, etc.). A malfunction may occur. • Do not put any foreign substance into the cassette loading slot. • Avoid violent shocks to the recording chassis during transportation. Remove the cassette tape from the unit for transportation. 5 Turn off the power to save electricity when not using the unit. Condensation 5 Condensation When cold beer is poured into a glass, water drops appear on the glass's surface. This phenomenon is called "condensation". When condensation occurs on the VCR's head drum and tape guides it may damage the tape. 5 Condensation occurs in the Head drum following cases: • When the VCR is moved from a cold place to a warm place. • In a room that has just been heated or in an area directly exposed to a cooler. Video tape • When there is excessive humidity. 5 When condensation is expected to occur Turn the power of the VCR on before use. 5 If condensation has occurred The VCR automatically ejects the cassette and the error indication "E-08" blinks on the display. Operation is disabled until the "E-08" indication on the display goes out.
