Sperry Marine recommends to have a regular gyrosphere maintenance
carried out by authorized service personnel every 18 months.
The recommended 18-month maintenance comprises the removal of
the gyrosphere, cleaning and inspection of the gyrosphere, mainte-
nance of the gyrosphere container and the re-installation of the gyro-
sphere using fresh supporting fluid. If necessary, the centering pin is to
be replaced.
The NAVIGAT X MK 1 is counting the system operating hours automati-
cally until a maximum level (18 months) is reached. When the maximum
level of operating hours is reached, the following message is displayed
automatically:
