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.

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
