Entering antenna height
The STC curve changes with respect to an- tenna height above the waterline. Enter an- tenna height above the waterline to optimize the STC curve.
1.Select “12. Antenna Height” on the instal- lation setup menu and press the [ACQ/EN- TER] key.
2.Operate the omnipad to select antenna height above the waterline; Low (~3 m), Mid (3~6 m) or High (6~10 m).
3.Press the [ACQ/ENTER] key.
Aligning heading (Adjustment sector:0~359.90)
You have mounted the antenna unit facing straight ahead in the direction of the bow. Therefore, a small but conspicuous target dead ahead visually should appear on the heading line (zero degrees).
In practice, you will probably observe some small error on the display because of the dif- ficulty in achieving accurate initial position- ing of the antenna unit. The following adjustment will compensate for this error.
1.Identify a suitable target (for example, ship or buoy) at a range between 0.125 to 0.25 nautical miles, preferably near the head- ing mark. To lessen error, keep echoes in the outer half of the picture by changing the range. Also, be sure the zoom and off center functions are off.
2.Select “9. Heading Alignment” on the in- stallation setup menu and press the [ACQ/ ENTER] key. The following message ap- pears on the display.
