The indicator lights up.
© <= (volume) control
Turning clockwise increases the volume of the equip-
ment connected or turning anticlockwise decreases
the volume.
@ @ (picture) control
Turning clockwise increases contrast with vivid col-
our and turning anticlockwise decreases contrast
with soft colour.
@ xX (brightness) control
Turn clockwise for more brightness and trun anti-
clockwise for less brightness. Optimum level will be
obtained with this control at the centre detent posi-
tion.
@ @ (colour) control
Turn clockwise for more colour intensity or turn anti-
clockwise for less colour intensity.
© HUE control
Turning clockwise makes skin tones greenish and
turning anticlockwise makes them purplish.
© H CENT (horizontal centering) control
Usually set this control at the center detent position.
When equipment is connected to the unit at the ANA-
LOG MULTIVANALOGIQUE, DIGITAL RGB input con-
nectors and VIDEO (either phono or BNC type) in-
puts, the display may be shifted off center to the left
or right of the screen. In this case, center the display
by turning this control clockwide or anticlockwise.
The display moves in the opposite direction the con-
trol is turned.
@ V (vertical) SIZE control
Usually, turn this control fully clockwise. To reduce
the picture size vertically, turn it anticlockwise. Pic-
tures of the equipment connected to the ANALOG,
DIGITAL RGB connectors, and VIDEO (phono and
BNC type) inputs can be adjusted.
When turning the control anticlockwise, RGB rasters
sometimes appear at the top of the screen, depend-
ing on the computer used.
@ AUTO/NTSC3.58 system select switch
Usually set this switch to AUTO. When receiving
NTSC3.58 system signals, set this switch to NTSC3.58
for better reception. ;

This unit is equipped with various multiconnectors for
your desired equipment to be connected.
VTR CONNECTION
Be sure to use a connecting cable that matches the con-
nector of your VTR (or portable VTR). Read the instruc-
tion manual of the VTR if you are not sure what type of
connectors your VTR has.
ep SE
Keep the VTR away from the unit, if the display or sound
is affected.

NOTES ON CONNECTION
@ Before connecting, make sure that the power to
each piece of equipment is turned off.
@ The plugs should be fully inserted into the jacks or
connectors. A loose connection may cause hum
and noise.
@ Match the colour when connecting the plugs to
jacks.
VTRs that are capable of receiving TV broadcasts
With this you will be able to—

If the VTR is equipped with a mini-type audio output
jack, use the plug adaptor supplied with the VMC-
612MS video cable.
Caution
When you connect a VTR to the phono connector and
another to the BNC connector at the same time, the
display may be affected. Use only one of these con-
nectors and the ANALOG MULTI/ANALOGIQUE con-
nector when you need to connect two VTRs.
Use an appropriate connecting cable to connect the
VTR to the ANALOG MULTI/ANALOGIQUE RGB (21 pin)
input connector.
In this case press the RGB button, and check that the
RGB/RVB input select switch is switched to ANALOG
MULTI/ANALOGIQUE so that the picture is displayed.
