Fit the instrument into the panel, fit the stainless clamp over the stud, fit and tighten
the wing nut finger tight only.
It is important that the O-ring rubber seal makes good contact with the panel to
prevent water getting behind the unit and entering the cavity behind the panel.
It is good practice to run the cables vertically downwards from the unit, even if they
later have to rise to connect to the vessel’s supplies. Doing so prevents any water
that might get onto the cables from running back along the cables and into the unit.
NORMAL OPERATION
When power is applied to the Clipper Compass, it executes a comprehensive internal
test routine. It then displays the heading. When first powered up, the displayed
heading may not be correct until the Compass alignment is done (see Engineering,
below). A typical display is shown on Figure 2.
CHANGING THE BACKLIGHT SETTING
Backlighting is provided to allow the unit to be seen at night. The backlit area is
restricted in the top corners of the display to concentrate the lighting in the areas of
interest (see Figure 2). The brightness of the backlighting is adjusted by pressing the
ILLUM button at any time during normal operation. Each press of the button increases
the brightness by one in the range 0 to 9, shown by the backlight indicator in the
bottom left of the display (see Figures).
A setting of zero switches the backlighting off, and a setting of 9 is maximum. In
common with all the other settings in the unit, the backlight setting is stored even
when the unit is off, so that it returns to the chosen setting whenever the unit is
powered up again.
