8 | Caution

• WARNING - Inverter Failure (alarm code 3)
• When checking fuses, turn "OFF" the power switch on the operating panel and disconnect the power cable

from the ship’s Distribution Terminal Board.

• WARNING
• When checking fuses, turn "OFF" the power switch, and further disconnect the power cable from the ship’s

distribution terminal board.

• CAUTION - Clarification
• Indicates potential risk of damage to equipment.

• CAUTION - Prohibition
• Do not use insulation tester or other device to test system insulation as it will damage internal electrical

components. Always disconnect the wiring connected to this system before testing related power distribution
lines with such testers.

• CAUTION - General use
• This system displays Gyro Compass heading and outputs the heading information externally. Although the

safety design such as the alarm function against failure, etc., is provided, at the present time there is no
perfect safety design. 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 in using this product. The use of this equipment does not absolve the user's
responsibility and obligation in practicing proper navigational techniques.

•  Observe the following CAUTIONS:
•  Always perform daily check to maintain normal system condition.
•  When anomalies are detected as a result of daily checks, investigate and repair at once to restore to normal

conditions and request advice from Alphatron service engineer.

• When the alarm system is activated during use, always check to confirm the cause and reinstate.

• CAUTION - Types of Alarm
• When an alarm regarding GPS (alarm code "c" or "d") is activated and the Gyro Compass' True Heading has

not been determined, first turn the steering mode to "MANUAL", or "Non Follow Up", then determine the True
Heading, because wrong heading information (repeater signal and serial signal) may be sent out.

• When an alarm regarding LOG (serial) (alarm code "P" or "U") is activated and the Gyro Compass' True

Heading has not been determined, first turn the steering mode to "MANUAL" or "Non Follow Up", then
determine the True Heading, because wrong heading information (repeater signal and serial signal) may be
sent out.

• When an alarm regarding LOG Contact (alarm code "u") is activated and the Gyro Compass' True Heading

has not been determined, first turn the steering mode to "MANUAL" or "Non Follow Up", then determine the
True Heading because wrong heading information (repeater signal and serial signal) may be sent out.

• When an alarm regarding the EXTERNAL HEADING SENSOR (alarm code "E", "F", "L" and "N") is activated,

the heading information immediately before the alarm was activated is sent. First turn the steering mode
to "MANUAL" or "Non Follow Up", and then determine the true heading. Once True Heading has been
determined, the system's heading is sent out.

• When the system is turned on, first turn the automatic steering system to "MANUAL" or "Non Follow Up" to

prevent course turning with larger angle.

• CAUTION - Start Up
• Start up this product after turning the automatic steering system to other mode than "AUTO".

• CAUTION - Setting Latitude Input
• Change of the latitude input system, or a large change of latitude value may cause a large change in the True

Heading. When on automatic steering, first turn the steering mode of the automatic steering system to
"MANUAL" to prevent a large change of course. Confirm the area around the ship is clear and turn to "AUTO"
steering again.

• CAUTION - Setting Latitude Input
• When an alarm regarding GPS (alarm code "c" or "d") is activated and the Gyro Compass' True Heading has
