Re-calibration of the Sensor unit
The direction of the Sensor unit relative to the vessel's heading
has to be recalculated only if the Sensor unit has been moved or
dismounted from its holder. Then the calibration procedure
described in General section, page 28 has to be followed for re-
calibration of the heading.
Processing unit
No special maintenance is required. It is advisable, however, at
the start of each season to make a visual inspection of the
terminals below the bottom cover (terminal cover) and check all
connections.
Display unit
The Display unit will under normal use require little
maintenance.
If the unit requires any form of cleaning, use fresh water and a
mild soap solution (not a detergent). It is important to avoid
using chemical cleaners and hydrocarbons such as diesel, petrol
etc.
Make sure that all open connectors on the Display unit are fitted
with a protection cap.
It is advisable at the start of each season to check all connections
to the unit and cover with Vaseline or WD40. If the Display unit
is not removed from the vessel, it should be covered with the
white protection cover.
Software upgrades
Software upgrades with improvements and new functionality
will regularly be offered. Download of new software version is
performed from an external PC by utilizing the Ethernet port on
the PC and the HS50 Processing unit. Some new software
releases will also require a new PROMM installed in the
Display unit.
