Panasonic AG-TL950 Operating Instructions Manual

Contents

7This 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 whichpenetrates the VCR (especially during outdoor use) also promotes the wear and deterioration of mechanical parts by causingpoor 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 cleaningtape alone cannot clean the entire tape transport mechanism, this should also be inspected periodically to prevent anyproblems that could result from a sudden failure.As replacement and adjustment of parts require advanced skills and specialized equipment, please contact the person incharge of professional video equipment at your nearest Panasonic-authorized service agent for servicing.1-2 Periodical MaintenanceMonitoring Usage TimeThe total operation time reached by an ordinary home VCRin 5 or 6 years may be reached by a professional VCR inas few as 5 or 6 months. Therefore, it is important that thetotal hours of operation be carefully monitored. An hourmeter in the on-screen display (see page 20) shows theaccumulated time. In the chart below, the hoursaccumulated in each month are shown in relation to thenumber of hours used per day. Times shown in the shadedarea indicate that maintenance should be performed.Running time 1000H 2000H 3000H 4000HDrum ass’y (including heads) ^ Pinch rollers ^ Drive parts ^ ^ ^ 1-3 Precautions5 CondensationWhen cold beer is poured into a glass, water dropsappear on the glass’s surface. This phenomenon iscalled “condensation”. When condensation occurs onthe VCR’s head drum and tape guides it may damagethe tape.5 Condensation occurs in thefollowing cases:• When the VCR is moved from acold place to a warm place.• In a room that has just been heatedor in an area directly exposed to acooler.• When there is excessive humidity.Condensation5 When condensation is expected to occurTurn the power of the VCR on before use.5 If condensation has occurredThe VCR automatically ejects the cassette and the errorindication “E-08” blinks on the display. Operation isdisabled until the “E-08” indication on the display goes out.Periodic MaintenanceCheck or replace the following mechanical parts accordingto the running time.Head drumVideo tape1 INTRODUCTION^ : Cleaning : Check or replace as required. : Replace• Maintenance requirements may vary depending on theoperating environment and usage.

If the internal temperature risestoo high, the tape may be damaged.5 When playing back a tape recorded on another VTR, theremay be some noise output even when trackingadjustments are carried out. This is not a malfunction.5 Do not leave the unit in the Still or Record Pause mode for along time as this may damage the tape.After about 3 minutes, this unit automatically enters the Stopmode.5 Handle the unit carefully• Do not place anything heavy on the unit (a monitor, etc.). Amalfunction may occur.• Do not put any foreign substance into the cassette loadingslot.• Avoid violent shocks to the recording chassis duringtransportation. Remove the cassette tape from the unit fortransportation.5 Turn off the power to save electricity when not using theunit.5 To clean the unit, just wipe it with a soft cloth.Use of thinner or benzene may dissolve or tarnish the surface.To remove stains, wipe it using a cloth dipped in water mixedwith a little amount of neutral detergent, and wipe it again witha dry cloth later on.5 Never put your hand into the front-loading tape door.If you do so, you may get hurt.
