5.4.4 Selection of Other Ships
The cursor in Graphic display can move with key or key.
When key is pressed, ships are selected by descending order of the setting SORT.
When key is pressed, ships are selected by ascending order of the setting SORT.
5.4.5 Auto Range Setting
After “AUTO RANGE” is set “ON” (valid), this function works under the condition shown below.
On condition that Graphic range set previously is smaller than the ship’s distance selected in the
list (located within 24NM), and then press DISP key and displays the Graphic screen.
The range is set automatically and is adjusted to its distance. Therefore the ship selected can be
confirmed in the Graphic display.
e.g.㧕If the Graphic range is set 0.75NM previously and A ship which is 4.85NM away from own ship is
selected in the list, the progress is shown below.
The range is changed 0.75NM into 6.0NM.

6. MAINTENANCE AND INSPECTION
The performance and longevity of this equipment depend on careful maintenance. To maintain the best
performance, the following periodic inspections are highly recommended.
(1) Keep the power supply voltage within the specified value (19-35Vdc).
(2) Know the condition of normal status when the equipment is properly functioning. Keep comparing
the current status to the normal status to immediately detect any malfunctions.
Do not attempt to check or repair the interior of this equipment by non-qualified
service personnel, as doing so may cause fire, electric shock or malfunction. If
any malfunctions are detected, contact our service center or agents.
6. 1 General Maintenance and Inspection
Below are listed general maintaining and inspecting items, which can be done with usual tools and
apparatus.
No. Item Maintenance and inspection
1 Cleaning
Gently clean the surface of the panel, knobs, switches, and cover with soft
cloth or silicon oil. No oil is needed because this unit has no moving
mechanisms inside.
2 Looseness
of parts
Inspect for looseness and correctly tighten the following:
Screws, nuts, knobs, switches and connectors.
3 Fuse
When checking and replacing the fuse, be sure the power is off.
If the power source fuse is blown, be sure to inspect the cause before
replacing the blown fuse with a new one.
4 Unit
Check whether there is discoloration of parts mounted to the unit.
When exchanging a unit, contact our service center or agents.
