STERN UP mode

The STERN UP mode rotates the HEAD UP

mode picture, relative and true bearings and

display graphics 180°. This mode is useful on

dual-radar tugboats when backing up; one ra-

dar shows HEAD UP and another shows

STERN UP. To enable the STERN UP mode,

turn on [STERN UP] on the [OPERATION]

menu.

Note: STERN UP mode is only available for

C-types.

1.31 How to Select a Range Scale

The selected range scale and range ring interval are shown at the upper left corner on

the screen. When a target of interest comes closer, reduce the range scale so that it

appears in 50-90% of the display radius.

1. Place the cursor in the [RANGE] box at the top left corner of the screen.

In the above example, the range scale is set to 0.125 NM and the interval between

range rings is set to 0.025 NM.

2. Left-click to lower the range; right-click to raise the range.

You can also select the range with the RANGE key on the control unit (not available

for RCU-015/RCU-016). Press "+" to increase the range, or press "-" to reduce the

range. Press and hold a key to successively change the range upwards or down-

wards.

Changing the plotter range (C-types only)

With the radar in standby (STBY) mode, you can change the plotter range by pressing

the RANGE key. In this case, “range” means the on-screen displayed distance from

the left-hand edge of the screen to the right-hand edge of the screen.

“+”: expands the range scale with the cursor location as the center.

“-”: reduces the range scale with the cursor location as the center.

Press and hold the + or - key to change the range scale continuously.
