(4) Warning regarding general caution for use of this system (See page 1-1.)
CAUTION
●
This system displays gyrocompass heading and outputs the heading information to the
outside.
Although the safety design such as the alert function against failure, etc., is provided,
there is no perfect safety design at the present time.
In addition, as this system has many important functions, it is hard to say that any one
can use this system without failure.
Failures or malfunctions of this system may cause distress, and full attention should be
paid on use of this system.
User's responsibility and obligation in insuring safe navigation and the proper exercise
of navigational techniques is in no way reduced by the use of this equipment.
The following cautions should be observed.
1. Always perform daily check to maintain normal system condition.
2. When anomalies are detected in the result of daily check, investigate and repair at
once to recover to normal conditions and request advice of our service engineer.
3. When the alert system operates during use, always check to confirm the cause
and recover the troubled point.
(5) Warning regarding kinds of function (See page 1-2.)
CAUTION
●
When an alert related to GNSS (alert code "c" or "d") is generated and the gyrocompass
true heading 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 GPS communication abnormality is
generated" in Chapter 3 Operation, for determination method of the true heading.
●
When an alert regarding to LOG (serial) (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.
●
When an alert regarding to the 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 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 (5) Countermeasures when LOG contact abnormality is
generated" in Chapter 3 Operating Method, for determination method of the true
heading.
●
When an alert regarding to the external heading sensor (alert code "E", "F", "L" and "N")
is generated, the heading information immediately before the alert generated is
outputted. Once turn the steering mode to "MANUAL" or "Non Follow Up", and then
determine the true heading. Refer to
“3.4.5 (3) Countermeasures when external
heading sensor related communication abnormality is generated" in Chapter 3
Operating Method, for determination method of the true heading.
After the true heading is determined, this system's heading is outputted to the outside.
●
When the system is switched, perform it after once turned the automatic steering
system to "MANUAL" or "Non Follow Up" to prevent course turning with larger angle.
