1 PRECAUTIONS
VCR
@ Avoid using the recorder in places subject to the
following conditions:
— extreme heat, cold, or humidity,
— dust,
~ vibrations, and
— poor ventilation.
© Be careful of moisture condensation.
Do not use the recorder immediately after moving it
from a cold place to a warm place. The water vapor
in warm air will condense on the still-cold video
head drum and tape guides and may cause
damage to the tape and the recorder.
@ Handle the recorder carefully.
* Do not block the ventilation openings.
* Do not place anything heavy on the recorder.
¢ Do not place anything which might spill on the top
cover of the recorder.
* Use in horizontal (flat) position only.
@ During transportation,
* Avoid violent shocks to the recorder during
packing and transportation.
* Before packing, be sure to remove the cassette
from the recorder.

@ Use video cassettes marked with WHS / SVHS!/
(WiIS| with this unit. C-cassettes can be used with a
C-cassette adapter (SA-CP11U) connected.
@ Video cassettes marked with WIWHS| are exclusively
for use with a video cassette recorder marked with
WWHS!. Loading such cassettes into existing S-
VHS or VHS cassette recorders may cause a

1 PRECAUTIONS
Head cleaning
Perform head cleaning even 20 hours to enjoy
clear pictures.
Video heads get soiled with repeated recording and
playback, resulting in rough, uneven picture.
Perform cleaning of the tape transport mechanism
every 20 hours with the provided head cleaning tape
dedicated to W-VHS. :
How to use the cleaning tape
1. Load the W-VHS dedicated head cleaning tape.
2. Press the PLAY button and then STOP button after
about 30 seconds.
Aad
Unload the head cleaning tape and execute a
usual recording and playback procedure on a W-
VHS cassette to see if audio/visual quality has
been recovered.
4, If tape quality does not pick up, repeat the
procedures 1. and 2. once or twice.
Cautions
@ Do not rewind the cleaning tape after every use (for
about 30 seconds). You have only to start at the
position where the tape stopped in previous
cleaning. Rewind to the beginning when the tape
has been used to an end.
@ 30 seconds are enough for one run of the cleaning
tape. To keep running the tape for longer than 45
seconds may damage the heads.
@ If sound and picture quality does not recover with
the cleaning procedures repeated three times, there
may be some other causes of trouble. Consult your
JVC dealer.
®@ The W-VHS dedicated cleaning tape can be used
100 times.
@ Recording or playback is not possible on the
cleaning tape.
@ Do not use any cleaning tape other than the W-
VHS dedicated cleaning tape for this machine.
®@ The W-VHS dedicated cleaning tape can be used
only with the video cassette recorder marked with
