3.4.3 Change Range (Observation Range Scale) [RANGE+/-]
Procedure 1 Press the [RANGE +] key to expand the observation range.
A larger observation range allows observation of a wider area.
However, objects are shown smaller as the range expands, and objects near own ship are
less likely to be detected. Therefore, use a lower-level observation range to observe the
area around own ship.
2 Press the [RANGE -] key to reduce the observation range.
Area around own ship can be observed in detail as the observation range is reduced.
Note, however, distant images cannot be displayed.
* Software button Ԙ located at the top left corner of the radar display described in Section 2.3.1 is also
available to switch the range.
