10.2 Preventive maintenance
Surface cleaning – to keep the CRXX cabinet and display screen clean, wipe
the surfaces with a clean damp cloth. For heavier cleaning, use a clean, damp
cloth which has been dipped in a solution of a mild dish detergent and water.
Wring out firmly before wiping the unit.
Never use cleaning solutions containing spirit, alcohol, gasoline or oils.
Electrical connections – periodically check the electrical connections. Make
sure that connections are tight and that no cables are frayed or worn.
Radar antenna - periodically check that the scanner’s fitting bolts are tight
and not corroded. Every 6 to 12 months an even coating of grease should be
applied to the entire surface of the antenna drive gear with a spatula or brush.
Most of the maintenance of the radar antenna should be left to qualified
personnel. If there are problems with the performance, please contact your
authorized dealer.
Warning! Do not open the radome before the cable between the radar
antenna and CRXX has been disconnected. It is not sufficient just to turn off
the power by the switch, as the radar antenna is still supplied power inside.
10.3 Repair and service
The CRXX is sealed and does not contain any user serviceable parts. Opening
of this unit will void its warranty. If the CRXX requires servicing or repair,
call your authorized SIMRAD dealer, but first check Troubleshooting in sec-
tion 10.1.
Spare parts – fuses may be bought from a chandler or a marine supply store.
Use only fuses specified for this unit – see 10.4 Specifications.
If you require a SIMRAD part, please contact your authorized dealer.
