1.7 Degaussing the CRT Screen
Each time the radar is turned on, the degaussing circuit automatically demagnetizes the CRT
screen to eliminate color contamination caused by earth's magnetism or magnetized ship
structure.
The screen is also degaussed automatically at certain time intervals. While being degaussed,
the screen may be disturbed momentarily with vertical lines. If you wish to degauss by manual
operation, open the tuning compartment and press the Degauss switch.

1.8 Initializing the Gyro Readout
With a gyrocompass interfaced with the radar, ship's heading is displayed at the top of the
screen. Upon turning on the radar, align the on-screen GYRO readout with the gyrocompass
reading by the procedure shown below. Once you have set the initial heading correctly,
resetting is not usually required. However, if the GYRO readout goes wrong for some reason,
repeat the procedure to correct it.
1. Press the RADAR MENU key to display the FUNCTIONS 1 menu.
2. Press the [0] key twice to display the FUNCTIONS 3 menu.
3. Press the [9] key to select GYRO SETTING option.
4. Rotate the EBL control to adjust the gyrocompass reading.
5. Press the ENTER key to confirm the setting.
