PRECAUTIONS
The WJ-MX50isa sensitive, high quality instrument and shouldbetreated with care. And because itis an electrical device, the
danger of electric shock existsifitis used inappropriately.
xDo 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.
xDonotabuse the instrument. Avoid striking, shaking,
etc. It could be damaged by improper handlingor
storage.
x Do not use strong or abrasive detergents when
cleaning the instrument body.
xDo not expose the instrument to water or moisture, and

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 referservicingto
qualified service personnel. Moisture can damage the
instrument and also create a danger of electric shock.
• Use the instrument under conditions where
temperaturesarewithin0°C-40°C, and humidity is
below 90'/.
IMPORTANT NOTICE FOR VIDEO INPUT SIGNAL
(1) If the input video signal does not meet with the PAL
colour 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 bereflectedina low quality picture.
(3)Ifthesource input video signal isveryjittery, as inthe
case of a poor VIR playback signal, this could cause a
disturbance insynchronization or colour.
(4) If tracking noise is seen on the TV monitor, this could
cause a disturbancein synchronization. Itis necessary
to adjust the trackingcontrolof the input VTR.
(5) When eithera charactergenerator signal or characters
froma 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 inputsignals,(due to AFC
timeconstant)
(7) When the External Key Video Signal issupplied to the
EXT. CAMERA INconnector, this signal will be used as
areference sync signal for the WJ-MX50. So if this
signal isjittery, as in the case of VTR playback signal,
this could cause a disturbance in synchronization.
