3.4 Adjustments
Do the following in the order shown to
adjust the remote display.
1) Adjustment of picture
1. Press the [POWER] key on the display
unit.
2. Adjust the gain referring to paragraph
1.8 on page 4.
3. Adjust the STC referring to paragraph
1.9 on page 4.
2) Heading alignment
A small but conspicuous target dead ahead
visually should appear on the heading line
(zero degrees). In practice, you will
probably observe some small error on the
display. The following adjustment will
compensate for this error, up to ±30
°.
1. Identify a suitable target (for example,
ship or buoy) at a range between 0.125
to 0.25 miles, preferably near the
heading line. To minimize error, keep
echoes in the outer half of the picture by
changing the range.
2. Press and hold down
and together
(about 10 seconds) to display the
