5-1-2 Section 5: Maintenance & Troubleshooting
ST290 Instrument System Owner’s Handbook
Periodically clean each ST290 instrument and keypad with a soft, moist,
lint-free cloth. Do NOT use chemical or abrasive materials.
When your instruments or keypads are not in use, always fit the
suncovers supplied.
Wind transducer
If the windvane is removed from its mounting block for any reason (e.g.
if the mast is unstepped), fit the blanking cover (supplied) to the
windvane mounting block connector.
Speed & Depth transducers
Refer to the Installation and Maintenance instructions supplied with the
relevant transducer.
Cabling
Periodically examine all cables for chafing or other damage, and for
security of connection. Where necessary, replace and/or re-secure.
1.2 Troubleshooting
If you think you have a fault, always check that the perceived problem is
genuine and not due to the way the system and/or instrument has been set
up (see Section 7, System Setup).
For example, if a chapter titleis not being displayedon an instrument, this
could be due to a fault, but it is more likely to be caused by one or more of
the following:
• The relevant transducer is not fitted to your boat.
• Chapter titles have been turned off during User Setup.
• All the pages in the relevant chapter have been turned off during User
Setup.
Preliminary procedures
Changes in the electronic environment may adversely affect the
operation of your ST290 system. Typical examples of such changes are:
• Electrical equipment has recently been installed or moved aboard
your vessel.
• You arein the vicinity ofanothervessel orshore stationemitting radio
signals.
