Panasonic WJ-MX50 - Manual (Page 4)

PRECAUTIONS
The WJ-MX50 is a sensitive, high quality instrument and should be treated with care. And because it is an electrical device, the
danger of electric shock exists if it is used inappropriately.
DON'T DO’S
Do not attempt to disassemble the instrument. In order
to prevent electrical shock, do not remove screws or
covers. There are no user-serviceable parts inside.
Do refer all servicing to qualified service personnel.
X Do not abuse the instrument. Avoid striking, shaking,
etc. It could be damaged by improper handling or
storage.
X Do not use strong or abrasive detergents when
cleaning the instrument body.
X Do not expose the instrument to water or moisture, and
do not operate it in wet or humid areas.
X Do not use the instrument in an extreme environment
where either high temperature or high humidity exist.
• Do handle the instrument with care.
Do use a dry cloth to clean the instrument when dirty.
In case the dirt is hard to remove, use mild detergent
and wipe gently.
Do take immediate action if ever the instrument does
become wet. Turn the power off and refer servicing to
qualified service personnel. Moisture can damage the
instrument and also create a danger of electric shock.
Use the instrument under conditions where
temperatures are within 32°F-104°F {0°C-40° C), and
humidity is below 907.
IMPORTANT NOTICE FOR VIDEO INPUT SIGNAL
(1) If the input video signal does not meet with the NTSC
color standard, this could cause a disturbance of
synchronization. {The picture may jitter or tear)
(2) If the signal to noise ratio (S/N) of the input signal is
very low, this may be reflected in a low quality picture.
(3) If the source input video signal is very jittery, as in the
case of a poor VTR playback signal, this could cause a
disturbance in synchronization or color.
(4) If tracking noise is seen on the TV monitor, this could
cause a distarbance in synchronization. It is necessary
to adjust the tracking control of the input VTR.
(5) When either a character generator signal or characters
from a key camera is supplied, the edge of the
characters might become rough as shown below under
certain electronic conditions.
( 6 ) Flag waving {top of picture curls) may appear when
certain VTR's are used as input signals, (due to AFC
time constant)
(7) When the Externa! Key Video Signal is supplied to the
EXT. CAMEFtA IN connector, this signal will be used as
a reference sync signal for the WJ-MX50. So if this
signal is jittery, as in the case of VTR playback signal,
this could cause a disturbance in synchronization.
