Instrument Maintenance - Four winns V458 Owner's Manual

Figure E15: Compass
After all personal equipment is installed, including all
electronics (VHF radio, GPS, chart plotter, etc.), the
compass must be properly calibrated. DO NOT rely
on the compass readings until initial adjust ment
(compensation) has been performed. The boat has a
factory installed compass, the manu factur er's instruc-
tions are provided in the owner's packet. Most areas
have local com panies that special ize in compass
adjustment. If unsure of the proper compensation
techniques, consider having the adjustment done
professional ly to insure accuracy and confi dence in
the compass.
NOTICE
During use, keep all extraneous metal objects
away from the compass. The close proximity of
metal objects (e.g., beverage cans) can cause
compass devi a tion.
G. Instrument Maintenance
The EVC system and the optional electronics
(if installed) should be maintained in accordance
with the manufacturer's operating instructions.
Should repairs need to made, do not attempt to repair
these units yourself. Repairs must be performed
by an authorized service technician.
The ignition switches and all electronics, controls, etc.
should be protected from the weath er when not in
use. Four Winns provides a canvas helm cover for just
such a purpose. Excessive expo sure can lead to
display and igni tion switch difficulties. If these units
and/or helm area itself come in contact with salt spray,
simply wipe the affected surfaces with a soft. clean
cloth dampened in fresh water.
