6 ST40 Speed Instrument Owner’s Handbook
Instrument
Certain atmospheric conditions may cause a small amount of
condensation to form on the instrument window. This will not harm the
instrument and will clear after the instrument has been switched on for a
short period.
Periodically clean your ST40 instrument with a soft damp cloth. Do
NOT use chemical or abrasive materials to clean the instrument.
Transducer
Refer to the Installation and Maintenance instructions supplied with the
transducer.
Cabling
Examine all cables for chafing or other damage to the outer shield and,
where necessary, replace and re-secure.
2.2 Fault finding
Preliminary procedures
If you appear to have a problem, first check the security of the
connections at the rear of the instrument and reconnect any that are
loose.
Changes in the electronic environment may adversely affect the
operation of your ST40 equipment. Typical examples of such changes
are:
• Electrical equipment has recently been installed or moved aboard
your vessel.
• You are in the vicinity of another vessel or shore station emitting
radio signals.
Fixing faults
All Raymarine products are subjected to comprehensive test and
quality assurance programmes prior to packing and shipping. However,
if a fault occurs, the following guidelines may help to identify and
rectify the problem.
