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 Panasonic-authorized service agent for servicing.
1-2 Periodical Maintenance
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.

1-3 Precautions
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
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.
• When there is excessive humidity.
Condensation
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.
Periodic Maintenance
Check or replace the following mechanical parts according
to the running time.

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 When playing back a tape recorded on another VTR, there
may be some noise output even when tracking
adjustments are carried out. This is not a malfunction.
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.
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 mixed
with a little amount of neutral detergent, and wipe it again with
a dry cloth later on.
5 Never put your hand into the front-loading tape door.
If you do so, you may get hurt.
