1.36.2 Trail time
Trail time is the interval at which the trail is plotted on-screen. You can change the trail
time as follows:
Using the control unit (RCU-028)
1. Place the cursor on the trail time setting inside the [TRAIL] box at the bottom-right
corner of the screen, then press the left button. You can also press the TGT
TRAIL key to cycle through and select the desired setting.
The options, in order, are: [OFF] o [15 sec] o [30 sec] o [1 min] o [3 min] o [6
min] o [15 min] o [30 min] o [CONT] o [OFF]...
Using the on-screen box
1. Place the cursor on the trail time setting inside the TRAIL box, at the bottom-right
of the screen.
2. Rotate the ADJUST knob to change the trail time. The time is changed in 30 sec-
ond increments
Note: When using the scrollwheel on the RCU-030 to change the trail time, the
time is changed in 30 second increments also.
Note 1: The timer displays the elapsed time of the selected trail. Use caution when
using this feature, as the displayed time is not the overall trail time. Also, when the trail
timer is displayed, the trail accuracy of other ship’s echoes may be lowered. When the
trail time reaches the preset interval, the timer disappears.
Note 2: The [CONT] option sets the trail time plotting as continuous. When the plotting
time reaches 29:59, the timer is hidden. The timer reappears when [TRAIL ALL
CLEAR] is selected, or when the range is changed.
1.36.3 Trail gradation
The trail afterglow can be displayed in a single tone or with gradual shading.
1. Select the [TRAIL] box at the bottom-right corner of the screen, then press the
right button to display the [TRAIL MENU].
2. Select [TRAIL GRAD], then push the ADJUST knob.
3. Select [Single] or [Multi] (Multiple) as appropriate, then push the ADJUST knob.
