(7) Setting of ship's speed input system
CAUTION
●
Change of the ship's input system or large change of ship's speed may cause large
change of the true heading.
During the automatic steering, once turn the steering mode of the automatic steering
system to "MANUAL" to prevent a large course changing, and after confirming
surrounding safety of own ship, turn to "AUTO" steering again.
CAUTION
●
When an alert related to GNSS (alert code "c" or "d") is generated and the true heading
of the gyrocompass has not been determined, once turn the steering mode to
"MANUAL" or "Non Follow Up", then determine the true heading because erroneous
heading information (repeater signal and serial signal) is possible to be outputted to the
outside.
Refer to "3.4.5 (2) Countermeasures when GNSS communication abnormality is
generated" in Chapter 3 Operating Method, for determination method of the true
heading.
CAUTION
●
When alert regarding to LOG (serial signal) (alert code "P" or "U") is generated and the
true heading of the gyrocompass has not been determined, once turn the steering mode
to "MANUAL" or "Non Follow Up", then determined the true heading because the
erroneous heading information (repeater signal and serial signal) is possible to be
outputted to the outside.
Refer to "3.4.5 (4) Countermeasures when LOG (serial) communication abnormality is
generated" in Chapter 3 Operating Method, for determination method of the true
heading.
CAUTION
●
When alert regarding to LOG (contact) (alert code "u") is generated and the true heading
of the gyrocompass has not been determined, once turn the steering mode to
"MANUAL" or "Non Follow Up", then determined the true heading because the
erroneous heading information (repeater signal and serial signal) is possible to be
outputted to the outside.
Refer to "3.4.5 (5) Countermeasures when LOG (contact) communication abnormality is
generated" in Chapter 3 Operating Method, for determination method of the true
heading.
CAUTION
●
The setting of the ship's speed input system (and its values for "MANUAL") is stored,
and when re-started, the previous ship's speed system setting is restored and starts.
When "MANUAL" is selected, stop after ship's speed setting is set to zero knot.
Also, when turned off and on again with "GNSS" selected, confirm that GNSS is
operating properly.
