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 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
24 volt battery bank through a circuit breaker and
continuously monitors two emergency high water
pumps, two bilge pumps and the bilge heat detector.
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 (See Fig. 6.3.1).
The BIM collects signals from critical engine
functions, generator oil pressure, bilge pumps, high
water emergency bilge pumps and bilge heat
detection 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.
The LCD display will read in two lines. For example,
at normal operation it will read:
