SAFETY PRECAUTIONS
WARNING:
Service should not be attempted by anyone unfamiliar with the necessary precautions for this recording or playback
equipment. The following precautions are necessary during servicing:
1. Many electrical and mechanical parts in this recorder have
special safety-related characteristics for providing protec-
tion against shock, fire and other hazards. These charac-
teristics often go unnoticed in a visual inspection, and the
protection afforded by them cannot necessarily be ob-
tained by using replacement components with higher rat-
ings (voltage, wattage, etc.).
2. Replacement parts having special safety-related charac-
teristics are identified in this manual, and in the schematic
diagrams, by the symbol ! . These components have
values that are of special significance to product safety.
Should any component (identified by the symbol ) need
to be replaced, use only the part designated in the parts
List. Do not deviate from the specified resistance, wattage,
and voltage ratings.
3. Before returning the set to the customer, always perform an
AC leakage current check on the exposed metallic parts of
the cabinet, such as terminals, screwheads, metal over-
lays, etc. to be sure that the set is safe to operate without
the danger of electrical shock, Plug the AC line cord directly
into a 120 V AC outlet. (Do not use a line isolation trans-
former during this check.) Use an AC voltmeter with a
sensitivity of 5000 ohms per volt (or more) as follows:
Connect a 1500 ohms, 10 watt resistor, paralleled by a 0.15
mfd, 150 VAC capacitor, between a known good earth
ground (water pipe, conduit, etc.) and the exposed metallic
parts, one at a time. Measure the AC voltage across the
1500 ohms resistor and 0.15 mfd capacitor combination.
Reverse the AC plug at the AC outlet and repeat the AC
voltage measurements for each exposed metallic part. The
measured voltage must not exceed 300 mVrms. This
corresponds to 200 µA AC. Any value exceeding this limit
constitutes a potential shock hazard and must be corrected
immediately.
4. Fuse symbol marks.

UNDERWRITERS LABORATORIES Standard
CAUTION "Risk of fire-replace fuse as marked"
For U.S.A.
Fuse rating is marked at

1. Monitor Selector Switch (VIDEO A/B)
Turn this Monitor selector switch A position for a
signal fed through the rear panel VIDEO A
connectors.
Then, turn this Monitor selector switch B posi-
tion for a signal fed through the rear panel
VIDEO B connectors.
2. Contrast Control ( CONTRAST)
Turn to adjust picture contrast according to your
requirement.
3. Brightness Control ( BRIGHT)
Turn to adjust picture brightness according to
your requirement.
4. Power Indicator
Lights when the power is on.
Lit: When the power is on.
Unlit: When the power is off.
5. Power Switch (POWER)
Press this switch to turn the power on or off.
1-2. REAR PANEL CONTROLS & CONNECTION
1. AC input socket (AC INPUT)
Connect the AC power cord (supplied) securely
to this socket and to a wall outlet.
2. Video input terminals (VIDEO IN)
These terminals are used to input a video signal
source to this monitor.
Connect to the video output of a VCR or an-
other monitor (for loop through connection) or to
a video camera.
3. Video output terminals (VIDEO OUT)
These terminals are used to output a video
signal from this monitor.
Loop-through output of the video in BNC
connector, then connect to the video input of
another monitor or a VCR.
4. Termination Switch (HI/75 Ω(Lo))
Select the input impedance (HI/75 ohm).
When using only one monitor, turn the termina-
tion switch to the 75 ohm position. When using
more than one monitor, set all of the termination
switch to the monitors to the HI position.
However, the last monitor termination switch
should be the 75 ohm position for proper line
termination.
5. Focus control (FOCUS)
Turn to adjust picture focus to optimum focus.
6. Sub-brightness control (SUB-BRI)
Turn to adjust picture brightness.
7. Vertical Size control (V-SIZE)

Adjust VR404 to make pattern upright.
Set the power switch "ON" and adjust
VR302 and VR304 until height for eye
comfort is obtained.
Horizontal width is adjusted by means of
the width coil L402 on the main PWB,
width standard hexagonal alignment tool.
Adjust L402 to make picture width within
"2" position.
Adjust the vertical linearity control VR301
for equal spaceing of lines between the
center extreme of scan.
The focus control may be adjusted for
optimum focus by VR405.
The raster is centered by rotating the two
small at the rear of the yoke.
Loosen the screw on the rear of deflection
yoke, rotating the yoke to correct position
tighten the screw.
Brightness can be controlled by VR406
and VR201 is the main control which is
controlled at exeternal side of front side.
VR402 is a sub-bright control which is
located on the main PWB.
The vertical hold is automatic stop rolling.
