1.10 Presentation Modes

This radar has the following presentation modes: Head-up, Head-up/TB, Course-up, North-up, and True Motion.

Selecting presentation mode

Press the [MODE] key on the panel at the right side of the display unit. Each time the [MODE] key is pressed, the presentation mode and mode indication at the upper-left corner of the screen change cyclically.

Note: When a failure occurs in the gyrocom- pass, the radar will automatically be switched to unstabilized presentation mode. All com- pass related data will read Relative values.

Loss of Compass Signal

When the compass signal is lost, the buzzer sounds once, the presentation mode becomes head-up and the compass readout shows xxx.x°. After restoring the compass signal, press the [MODE] key to display the compass readout. Readjust the compass readout as shown on page 1-4. Also HDG SIGNAL MISSING appears at the bottom of the screen.
