5 Maintenance and Servicing
5.1 Preventative Maintenance
The UAIS transponder system is an essential part of the ship’s navigation system
and is a vital component for the safety of the ship and its crew. It is therefore very
important to maintain the system and its installation to a very high standard. The
design of the UAIS transponder ensures that maintenance can be kept to a
minimum, however it is good practice to perform a performance check at least once
every week.
5.2 VDU Touch-Screen
To optimise performance of the touch-screen VDU and cabinet, ensure they are
kept clean and grease-free. Use a clean damp cloth, or for heavier deposits use a
clean, damp cloth and a mild solution of dish washing detergent and water. Do not
use any spirit or alcohol based solvents, gasoline or oils.
5.3 Electrical Connections
Periodically check the electrical connections; ensure that no cables are frayed or
worn, and that all connections are tight and sound.
5.4 Repair and Service
With the exception of the fuses located on the Screw Terminal Board, there are no
user serviceable parts. Changing fuses is described in Section 6 – Troubleshooting.
Removal of the inspection plates other than by an Authorised Service Technician
will void warranty. If having followed the Troubleshooting Guide (Section 6) UAIS is
still inoperable, please call your local Service Centre.
5.5 Spare Parts
Use only manufacturers genuine spare parts. No liability can be accepted for
equipment failure due to incorrect replacement parts being used.
5.6 World-wide Sales and Service
For a complete list of worldwide sales and service agents, please contact your
product supplier.

Changing a fuse
There are two fuses, located on the Screw Terminal Board, which are designed to
be changed by the user. These are the only user servicable parts.
Fuse description Fuse value Part No.
Main system fuse 10.0 Amp 99-077
VDU system fuse 1.0 Amp 99-076
Switch off the Transponder, undo the six screws retaining the cover, then lift off the
cover. Ensure that the power is off before attempting to remove a fuse. The fuse
link is visible through the transparent body of the fuse.
Ensure that the fuses are not interchanged. The values are clearly marked on the
board.
When the fuses have been checked to be intact, replace the cover, fit the six
screws and tighten carefully.
