2. INITIAL SETUP
How to align the antenna heading
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).
You may observe a minor bearing error on the display. This is due to the difficulty in
orienting the radar accurately. The following adjustment will compensate for the error.
1. Select a range between 0.125 and 0.25 NM and set the mode to “head up“.
You can select a range by a pinch action. The range and range ring interval ap-
pear at the bottom left of the screen.
For TZTBB, you can also control the range in the operation as follows. Tap the
radar scale box at the bottom left-hand corner of the screen to display the slider
bar. Drag the circle icon to set the range scale.
2. Turn the vessel’s bow toward a target.
3. Press the
Home key (or tap the Home icon), then select [Menu] icon, [Radar], and
[Antenna Heading Align] in that order to show the numeric software keyboard.
4. Key in the offset value so that the target is at the very top of the screen (setting
range: +/- 0° to 180°, +: clockwise direction, -: counterclockwise direction), then
tap [Save].
5. Confirm that the target echo is displayed at correct bearing on the screen.
