Routine checks

CAUTION:
The control unit does not contain any user serviceable parts.
It should be serviced only by authorized Raymarine service
technicians.
The control unit is a sealed unit. As a result, user maintenance is
limited to the following checks:
•
•

Cleaning the display

CAUTION:
Take care when cleaning the display. Avoid wiping the display
screen with a dry cloth as this could scratch the screen coating.

EMC advice

•
•
make sure all cable connectors are firmly attached
examine the cables for signs of wear or damage – replace any
damaged cables
Never use chemical or abrasive materials to clean the control unit.
If it is dirty, wipe it with a clean, damp cloth.
In certain conditions, condensation may appear inside the display
screen. This will not harm the unit, and you can clear it by
switching on the illumination for a short time.
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).
