How to Select the Interface for Heading Input
When a gyrocompass is connected, the ship’s heading appears on the right side of the
screen, in the data display area.
Heading input format can be selected as follows:
1. Open the menu.
2. Select [7 INFORMATION BOX].
3. Select [2 OWN SHIP INFO].
4. Select [2 HDG]. The [HDG] menu appears.
Note:
You can also access the [HDG] menu from
the on-screen box. Place the cursor on the [HDG
X
] indication in the heading box at the top-right of
the screen, then right-click.
5. Select [2 HDG SOURCE].
6. Select [GYRO1] or [GYRO2] as appropriate.
7. Close the menu.
Note 1:
The heading sensor must be able to follow a minimum ROT of 20° per second.
Heading sensors with a lesser capability may degrade the performance of echo aver-
aging, trails and TT. The data refresh rate should also be as short as possible. If the
refresh rate is too long, the ability to follow courses lessens, thereby affecting the per-
formance of echo averaging, trails and TT.
Note 2:
For IMO-types, Where the heading source is other than the heading sensor
(for example, and EPFS device), the sensor indication is displayed in yellow color.
