correct operation during installation, or servicing
(see Figure 8)
.
Starting Dealer Mode
Dealer Mode
function is activated by pressing and holding in all four
control buttons for two seconds until the “
sunburst
” sequence begins. After
a sequence of five “sunbursts”, the display will show two circles of test dots
(8 dots on the inner circle, 6 dots on the outer circle). The dots are spaced
at 45-degree angular intervals, and include the four cardinal points. The
outer circle of dots must be located halfway between the inner and outer
range rings.The inner circle of dots encompasses the “
walking dot
”, near
the center of the display. Using the “
Zoom in
” and “
Zoom out
” buttons to
change ranges, ensure that these dot circles are repeated on each of the
50, 100, 200 nm ranges.The dots zoom off scale on the 25 nm range. With
dot circles plotted on the display, and aircraft gyro compass operating,
bearing correction can be checked by rotating the aircraft, or the compass.
The dot circle must rotate in the opposite direction to that of the plane, and
by an equal amount.

The Display may be returned to normal operation by pressing the two right
buttons
