3.3 SCREEN CONTROLS

The screen controls can be adjusted for optimum trace, text and spot quality by
the controls to the left of the screen.
Figure 3.2 Screen control area
The brightness on the screen is adjusted by two controls, one for the trace and
one for the text.
• Turn the TRACE INTENSITY control clockwise and verify that only the
brightness of the trace increases.
• Turn the TEXT INTENSITY control clockwise and verify that only the
brightness of the text increases.
The sharpness of the trace and text is optimized by the FOCUS control.
When you are making photographs
or are in a dark environment, you
can use the ILLUMINATION control
to illuminate the graticule of the
screen.
The trace is adjusted in parallel with
the horizontal graticule lines by the
screwdriver-controlled TRACE
ROTATION control.
