• CAUTION - Setting Latitude Input
• When "GYRO" is selected for the latitude input system, latitude is automatically updated by the ship's speed

and the Gyro Compass True Heading. (When the ship's speed input system is "MANUAL", it is not updated
automatically.) During navigation, confirm once every two hours that the ship's actual latitude coincides with
the indicated latitude.

• CAUTION - Setting Latitude Input
• Press ACK/ENT switch (4) to complete the setting. Changed setting is not updated unless pressing ACK/ENT

switch (4).

• CAUTION - Setting Speed Input
• Change of the ship's input system or large change of ship's speed may cause large change of the True

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

• CAUTION - Setting Speed Input
• 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.

• CAUTION - Setting Speed Input
• 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.

• CAUTION - Setting Speed Input
• 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.

• CAUTION - Setting Speed Input
• The setting of the ship's speed input system (and its values for "MANUAL") is automatically saved. When re-

starting, the previous ship's speed system setting is activated. When "MANUAL" is selected, stop after ship's
speed setting is set to zero knots. Also, when turning off and on again with "GPS" selected, confirm that GPS is
operating properly.

• CAUTION - Setting Speed Input
• Press ACK/ENT switch to complete the setting. Changed setting is not updated unless pressing ACK/ENT

switch.

• CAUTION - Setting "Rate of Turn Filter Constant"
• Press ACK/ENT switch to complete the setting. Changed setting is not updated unless pressing ACK/ENT

switch.

• CAUTION - Confirmation True Heading
• When the Gyro Compass' True Heading is set again, the repeater indication value and the serial signal Gyro

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

• CAUTION - Confirmation True Heading
• Press ACK/ENT switch to complete the setting. Changed setting is not updated unless pushing ACK/ENT

switch.

• CAUTION - System Selection
• System selection (switching) may cause a large change of True Heading. When on automatic steering, first

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

• CAUTION - Monitoring in Progress
