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

•Douse 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 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.

rear panel The unit is now in stand-by mode. No
operations can be executed yet.
A-2. RESET Switch
1. ON position • • • Factory preset operation mode
It is recommended t o normally keep t h e RESET Switch
(109)in the ON position. It would be helpful in case of
unexpected operational failure.
2. OFF position • • • Field Preset operation mode
The status of the operation mode will be remembered
when the power of the unitis turned off. And this
status, without Still, Strobe and Special function, is
later recalled when the power is restored.
2. Press the OPERATE Button (1) on the operation panel
The unit is now inoperation mode and the Cooling Fan
(130) located on therear panel startsto rotate. The

RESET Switch (109) was already in the ON position.
A-3.DEMO Switch
1. ON position
The preprogrammed demonstration of the built-in
Effectfunctions of theWJ-MX50 will beautomatically
displayed on an attached video monitor.
Note:
This feature is useful for demonstrating functions
to a new user to help familiarize him/herself with
the unit.
2. OFF position
The unit reverts to standard operation mode.This
switch is normally set to the OFFposition.
Notes:
1 If you donotuse the unit for an extended period
of time or to shut off the power completely, switch
off the MAIN POWER Switch (131).
2. If the Cooling Fan (130) does not rotate, turn off
and disconnect the AC power cord. Call service
personnel beforeattemptingfurther use.
3. The power of WJ-MX50 can be turned on from
the Stand-by mode by turning on the power of
AG-A800. In this case the LED of the Mix Select
Button (73) turns on instead of the Wipe Select
Button(74).
