Furuno far-2805 series Manual De Usuario

This paragraph describes how to cure hard-
ware and software troubles which should be
carried out by qualified service personnel.

Note: This radar equipment contains complex
modules in which fault diagnosis and repair
down to component level are not practicable
by users.

All adjustments of radio transmitter during or
coinciding with the installation, servicing, or
maintenance which may affect the proper op-
eration must be performed by or under the im-
mediate supervision and responsibility of a

person holding an operator certificate contain-
ing a ship radar endorsement.

This is what the U.S. Codes of Federal Regu-
lations part 80.169 implies (not exact extract).

As such, every administration sets forth its own
rule; service personnel must be aware of this
kind of competency requirements.

When making a service call to your service
agent, check S/N and symptom beforehand.
