below every 3 to 6 months to keep the radar sensor in good working order. Observe
the safety instructions at the front of this manual when working on the mast.
Check point Action
Fixing bolts
• Corrosion
• If they are tightly fastened • Replace corroded bolts.
• Tighten loosened bolts.
• Coat new bolts with marine sealant.
Radome
• Cracks
• Foreign material If a crack is found, repair it temporarily with a small
amount of sealing compound or adhesive. Bring the unit
to your dealer for permanent repairs.
Foreign material on the radome can cause a consider-

freshwater-moistened cloth. Do not use commercial
cleaners to clean the sensor; they can remove paint and
markings or deform the plastic.
