PRECAUTIONS
The WJ-MX 121s a sensitive, high quality instrument and should be regarded as such. Because it is an electrical device, the danger of
electric shocks exists if it is used carelessly.
DON’T
DO'S
Do not attempt to disassemble the instru-
ment. In order to prevent electric shock, do
not remove screws or covers. There are no
user-serviceable parts inside.
Do not abuse the instrument. Avoid striking,
shaking, etc. It could be damaged by improp-
er handling or storage.
Do not use strong or abrasive detergents
when cleaning the instrument body.
Do not expose the instrument to water or
moisture, and do not operate it in wet areas
of it is wet.
Do not use the instrument in an extreme
environment where high temperature or high
humidity exist.
Important Notice for Source 1 and 2 Video Signal:
(1)
If the input video signal does not meet with the PAL
colour standard or the CCIR B/W standard video
signal, this could cause a disturbance of synchroni-
zation.
If the signal to noise ratio (S/N) of the input signal is
very low, this may be reflected in a low quality pic-
ture.
If the input video signal Is very jittery, as in the case
of poor VTR playback signal, this could cause a dis-
turbance in synchronization or colour. If a VTR play-
back signal and a camera signal are to be mixed,
itis highly recommended that the VTR playback sig-
nal be assigned to VIDEO 1 and the more stable
camera signal be assigned to VIDEO 2 by the IN-
PUT MODE SELECTION SWITCHES ® .
However, if the input video signal to VIDEO 1 is ex-
tremely jittery, disturbance of synchronization or
colour may occur even with a camera signal as-
gned to VIDEO 2.
Ss
e Dorefer all servicing to qualified service per-
sonnel.
e Do handle the instrument with care.
e 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.
e Do take immediate action if ever the instru-
ment does become wet. Turn the power off
and refer servicing to qualified service per-
sonnel. Moisture can damage the instrument
and also create the danger of electric shock.
e Use the instrument under conditions where
temperatures are within 0°C — 40°C, and
humidity is below 90%.
When either a character generator signal (from WV-
KB12) or characters from a key camera is supplied,
the edge of the character might become tough as
shown below under the certain electronic con-
ditions.
Flag waving (top of picture curls) may appear when
certain VTR’s are used as input signals (dueto skew
errors) or may appear due to the characteiStics of
the video monitor (due to AFC time constant $s).
