Your compass, properly corrected, will indicate
magnetic North (not true North). A compass must
be adjusted by a qualified person. The reason for
this is that nearby instruments or objects containing
magnets or current-carrying electrical wires will
influence the compass reading. This is especially
true if you add electronic devices to the helm
station.
After your compass has been professionally
adjusted. You will be given a deviation card or chart
indicating the correction to be applied when laying
out a compass course or making navigational
calculations. Keep this correction card or chart
at the helm.
NOTE: The compass adjustment is only good for
the equipment arrangement that existed at the time
of the adjustment. If you place different equipment
or remove equipment from the vicinity of the
compass, you cannot rely on the compass reading.
The compass must be readjusted by a qualified
person after equipment is added or removed from
the vicinity of the compass.
NOTE: The compass roses shown on navigational
charts have both true North and magnetic North
directions superimposed. Make certain you plot
course compass directions from the magnetic
North compass rose.
When not in use, the compass should be protected
from excessive and prolonged sunlight. If your
compass becomes sluggish or erratic, it should be
serviced by an authorized repair station.
To keep the plexiglass dome free from scratches,
remove salt deposits and dust with a damp cloth.
An occasional treatment with paste wax will help
preserve the dome surface.

The Systems Monitor located at the control station
consists of a Display Control Module (DCM) located
at the control station and a Bilge Interface Module
(BIM) located on the bilge component board. The
DCM and BIM are connected to each other by a
coax cable and the BIM is continuously looking at
all inputs for an alarm condition.
The Systems Monitor is connected directly to the
12 volt battery bank through a circuit breaker and
continuously monitors the bilge pumps and
emergency high water pumps. The engine and
generator functions are only active when ignition
voltage is turned on. The circuit breaker is on the
main DC breaker panel located on the bilge
component board.
The BIM collects signals from critical engine
functions, generator oil pressure, bilge pumps and
high water emergency bilge pumps and transmits
that information to be displayed on the DCM.
The features of the DCM include a two line LCD
display with backlighting of the display, audible alarm
and an Audible Reset/Alarm Select push button
switch.
