PRECAUTIONS

The WJ-MX30 is a sensitive, high quality instrument and should be treated with care. Because it is an electrical device, the danger

of electric shock exists if it is used inappropriately.

DON'T

Do not attempt to disassemble the instrument. In order
to prevent electric shock, do not remove screws or
covers. There are no user-serviceable parts inside.

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 on

extremely high temperature or high humidity.

IMPORTANT POINTS FOR VIDEO INPUT SIGNAL

DO'S

Do refer all servicing to qualified service personnel.

• 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 the instrument becomes
wet. Turn 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 ambient conditions of 0°C to

40°C in temperature, and below 90"/o in humidity.

(1) Failure of input video signals to meet the NTSC color

standard can cause a disturbance of synchronization.
(The picture may jitter or tear)

(2) A very low input signal to noise ratio (S/N) may result in

a low quality picture.

(3) A very jittery source input video signal, for example, a

poor VTR playback signal can cause a disturbance in
synchronization or color.

(4) Tracking noise on the TV monitor can cause a

disturbance in synchronization. It is necessary to adjust
the tracking control of the input VTR.

(5) When either a character generator signal or character

input from a key camera is supplied, the edge of the
characters might become rough as shown below under
certain electronic conditions.

Flag waving (top of picture curls) may appear when a

(6)

certain VTR is used to supply input signal, (due to AFC
time constant)

When an external key video signal is supplied to

(7)

the EXT. CAMERA IN connector, it will be used as
a reference sync signal for the WJ-MX30. A jittery
VTR playback signal, if used as such, can cause a
disturbance in synchronization.
