Adjusting the
contrast on
the display
To improve the quality of the representation on the display it may be neces-
sary to adjust its contrast. This can be done by rotating the trimmer (C) at
the back of the VT (see Page 4-9 or Page 4-10); turn it (using a small screw-
driver or a trimmer tool) in one direction and, if the display quality wors-
ens, turn it the other way.
