NORMAL OPERATION - ALL UNITS
When power is applied to the master unit, the repeater unit runs its own self-test procedures,
and commences repeating the master's display when the master unit's self tests are complete.
If Engineering is being done on the Wind or Compass master units, the repeater does not
display the progress, but shows “On” to show that it is waiting for normal operation to begin
in the master unit.
CHANGING THE BACKLIGHT SETTING
Backlighting is provided to allow the unit to be seen at night. In the same way as for the
master units, the backlit area is restricted in the top corners of the display to concentrate the
lighting in the areas of interest. The brightness of the backlighting can be adjusted at any
time independently of the backlight setting of the master unit. the brightness is adjusted by
pressing the ILLUM button. Each press of the button increases the brightness by one in the
range 0 to 7, shown by the backlight indicator in the bottom left of the Repeater display.
A setting of zero switches the backlighting off. 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.
ENGINEERING - ALL UNITS
Engineering settings means those adjustments which seldom need changing, but which
affect how the unit operates. The settings (as are all those which can be selected in normal
operation too) are stored even when the power is disconnected. The available Engineering
settings depend on the Repeater unit, as follows.
In the Clipper Echosounder repeater, no Engineering settings can be done, so that there
can be no confusion between the master and repeater. The settings of the gain delay, feet
or metres, and the choice of keel or surface depth display can be selected only by the
master unit.
In the Clipper Log repeater, no Engineering settings can be done, to prevent errors confusion
between the two units.
In the Clipper Wind Repeater, no Engineering functions are available, because the dead-ahead
position should be set from the master unit alone. Alteration of the pointer style is available at
the repeater because it is not an Engineering setting.
In the Clipper Close-Hauled Display no Engineering settings are available.
In the Clipper Compass Repeater, all of the Engineering functions are available.
Magnetic or True variation is not available. This restriction is to ensure that the master and
Repeater cannot be at odds in their heading indication.
For full details of Engineering functions refer to the Clipper Compass Manual.
