Care & Maintenance
The Vector G2 & G2B GPS Compasses haves been designed to provide many years of
reliable service. The following care and maintenance tips will help to ensure the longevity of
your Vector.
Protection of Wires and Cabling
After installation, ensure that the system components are securely mounted and will not
shake loose due to the vibrations that can be expected in a marine vessel.
Ensure that the cable to the G2 is well secured with clamps or alternative fasteners.
Many potential problems can be avoided by ensuring that cabling and wiring do not cause
any strain on the connectors.
Periodic Checks
After the first six months of operation, a thorough examination of the entire G2 system MUST
BE UNDERTAKEN. Verify that all electrical connections, cables, clamps, mounting brackets,
and mechanical connections are secure.
An ANNUAL inspection should be undertaken thereafter.
General Precautions
A few precautions will keep the unit in prime condition:
• The G2’s enclosure does not require any special maintenance. An occasional
cleaning is suggested; use a damp cloth and mild soap.
L Do not use abrasive cleaners or chemicals.
• Avoid exposing the enclosure to solvents, acids, and bases – some of these may
weaken the plastic.
• The G2’s enclosure is designed to be weatherproof and splash resistant, but it should
not be immersed in water for a prolonged period of time.
• Environments exceeding a maximum temperature of 85°C or below a minimum
temperature of -40°C MUST BE AVOIDED.
Repair
There are no user-serviceable parts or adjustments inside the G2’s enclosure. Should the
unit become damaged in any way, return it to an authorized ComNav Dealer.
Fuse Replacement
There are no fuses used inside the G2 itself. However, it is strongly recommended that a
fuse (or circuit breaker) be installed in the G2’s Power wiring (see page 17).
L If the fuse/breaker blows, determine the cause before
replacing/resetting!!
