Chapter 3: Maintenance & Fault Finding
This chapter provides information about maintaining your wheel
pilot system, obtaining product support and solving common
problems.
3.1 General maintenance
CAUTION:
The control unit does not contain any user serviceable parts.
It should be repaired only by authorized Raymarine service
representatives.
Display condensation
• In certain conditions, condensation may appear on the LCD
window. This will not harm the unit, and can be cleared by
switching on the illumination for a while.
Routine cabling checks
• Make sure all connections are firmly attached.
• Examine the cable for signs of wear or damage – replace any
damaged cables.
Cleaning the wheel pilot
• If the wheel drive or control unit are dirty, wipe them with a clean,
damp cloth.
• Never use chemical or abrasive materials.
EMC advice
• When powered up, all electrical equipment produces
electromagnetic fields. These can cause adjacent pieces of
electrical equipment to interact with one another, with a
consequent adverse effect on operation.
• To minimize these effects and enable you to get the best possible
performance from your Raymarine equipment, guidelines are
given in the installation instructions, to enable you to ensure
minimum interaction between different items of equipment,
i.e. ensure optimum Electromagnetic Compatibility (EMC).
