1.38 Degaussing Interval

The screen is degaussed automatically at certain time intervals, as well as each time the radar is turned on, to demagnetize the CRT screen to eliminate color contamination caused by earth’s magnetism or magnetized ship structure. You can select the degauss- ing interval and the degaussing degree as follows:

1.Press the [MENU] key followed by the [0] key twice to select OTHER.

2.Press the [0] key twice to select the OTHER menu.

4.Press the [2] key to select desired de- gaussing interval (OFF, 1, 5, 10 min) from the DEGS INTV field, and then press the [ENTER/SELECT] key.

5.Press the [3] key to select desired de- gaussing degree (45° , 90° , 135° ) from the

DEGS DEG field. For example, selecting 45° will automatically degauss the screen

when the ship makes a turn which is be- tween 45° and 89° .

6.Press the [ENTER/SELECT] key followed by the [MENU] key.

2.Press the [8] key twice to select display the NAV DATA menu.

3.Press appropriate numeric key to turn data on/off, select format, etc. Press the [ENTER/SELECT] key after setting each option. Water temperature and depth dis- plays are off in the default setting.

Note 1: OFF in the OS POSN field simply erases own ship position data; it does not stop input of nav data from a navigation device.

Note 2: TIME DIF selects time system to use; UTC or LOCAL. UTC = Local + Time Dif.

4. Press the [MENU] key.

All navigation data may be turned on/off by the keying sequence of [MENU], [0] (twice) and [5].
