3.3.3 How to automatically change track color for own ship with
depth
The track color for own ship changes with depth when selecting [9. WTR DEPTH] at
step 3 in section 3.3.1. There are two methods by which track color may be changed
according to depth: by preset depth range or depth variation.
How to change track color by preset depth range
The own ship track is displayed in the same color when the depth is within a preset
range. For example, you can set up to paint the track yellow when the depth is be-
tween 500 and 600 ft.
1. Press the MENU key to open the main menu.
2. Select [4. MARK/TRACK SETTING].
3. Select [TRACK COLOR BY DEPTH] on page 3.
4. Select [RANGE].
5. Set the depth range as desired. For example, to change track color to red when
the depth is more than 1000 ft, do the following:
1) Select [RED].
2) Press the
1 , 0 , 0 , 0 , 0 keys.
3) Set depths for other colors similarly.
Note 1: The depth should be set in ascending order from BLUE.
Note 2: The depth less than the one set at BLUE is displayed in WHITE.
6. Press the DISP key to close the menu.
How to change track color by depth variation
This setting paints the track in up to five colors according to depth variation selected.
The setting [EV. 2], for example, paints the track red when the depth is between 600
and 602 ft; yellow when the depth is between 603 and 604 ft. Thus, the track color
changes green, light-blue and purple in 2 ft steps. When the depth becomes 610 ft,
the track color returns to red (see the figure below).
