• True bearing display (north-up display) "North" is displayed as direct north of the PPI screen. Even when the bearing of the ship's bow changes, the bearing of the PPI image does not change. (Gyrocompass or other device that provides bearing information is required.) The ship rotates in the starboard direction The ship's heading marker rotates clockwise. • Course-up display The bearing of the ship's bow is always directly at the top of the PPI screen when the BRIL/HL OFF key is continuously pushed (course setting). Even when the bearing of the ship's bow changes, the bearing of the echo image on the PPI screen does not change and the ship's heading marker rotates to the extent of the change in the bearing of the ship's bow. When the heading changes significantly, the course should be reset by pushing the BRIL/HL OFF key continuously. (Gyrocompass or other device that provides bearing information is required.) The ship rotates in the starboard direction The ship's heading marker rotates clockwise. BRIL HL OFF 184
• In order to change the method of bearing display on the PPI screen, it is necessary to input the bearing information from a navigation device. Please refer to "3.6.1 Obtaining information on bearing" with respect to bearing display. Course setting in course-up up mode (a) Continue to hold down the BRIL/HL OFF key. The course will be set at the top of the PPI screen. 3.3.18 Simultaneously measuring the bearing, distance and travel time to the target The cursor function is used for this measurement. The cursor that is used here is indicated by a "+" mark on the PPI screen. By using this function, in addition to the distance to the cursor, the bearing and travel time to the cursor position may be obtained. • In order to obtain the travel time, it is necessary to input the ship's speed information from a navigation device. Please refer to "3.6.2 Obtaining information on speed". 185
