7.6 Maintenance

Certain atmospheric conditions may cause condensation to form on the
RayData display window. This will not harm the instrument and can be
cleared by increasing the illumination setting to HI.
Maintaining satisfactory operation of your RayData will depend on how
well you care for the equipment. The following basic maintenance tips
can save you time and money, as well as prevent unnecessary and
premature failures:
• Always keep the unit as clean as possible.
• Use a soft, clean cloth for cleaning. Do not use abrasive cleansers,
chemical cleaners or solvents – use glass cleaners or a suitable
general purpose detergent.
• Examine the cables for chafing or abrasions; clean and repair as
necessary.

7.7 Servicing

The most common faults encountered are due to poor connections and
poor power supplies. You should check all connections and power
supplies thoroughly, checking that the power supply cable is sound and
that all connections are tight and free from corrosion, before scheduling
a service visit or returning the unit.
When running cables, consider the following:
• Avoid running cables through bilges, and secure any coiled lengths
at regular intervals.
• Avoid running cables close to fluorescent lights, engines, radio
transmitting equipment etc.
• Check cabling for chafing or damage to outer casing, replace where
necessary and re-secure.
