7.1.2 In the middle of the exposed printed circuit board
below the display a variable resistor can be seen.
7.1.3 Power up the MultiGen and using a screw driver
adjust variable resistor to achieve optimum clarity ,
contrast and viewing angle of the display, in the required
mounting position.
7.1.4 Replace the front cover and the two side screws.
7.0 Contrast / Viewing angle adjustment. It is possible to
adjust the MultiGen display contrast / viewing angle if the
product is to be mounted in an unusual position. The
MultiGen is calibrated to give the best contrast and
viewing with the product mounted in a panel at a height of
1.6 metres and viewed square on (12 o'clock). This allows
the display to be seen over a wide viewing angle looking
squarely at the display, down at the display or at up at the
display.
If, for example, the MultiGen was to be mounted in a
control desk that has the MultiGen mounted at an angle of
45 degrees with the operator looking down at the MultiGen
it may be necessary to adjust the contrast control. This is
simply performed by adjusting an internal variable
resistor.
7.1.1 Remove the front cover by removing the 2 side
screws.
WARNING : high voltage present on pcbs.
