Dangerous (target) list
Dangerous targets are targets which are calculated to be on a collision course with
your vessel. When a dangerous target is detected, the target and its available details
can be viewed in the [DANGEROUS TARGET LIST].
The operations available from the [DANGEROUS TARGET LIST] are the same as the
[TARGET LIST] operations. See section 2.5.1 and section 2.5.3 for details.
Note:
When no dangerous targets are detected, the list shows the message "= NO
TARGET =".

How to interpret the [TARGET DETAIL] screen
The [TARGET DETAIL] screen shows available detailed information about the select-
ed target.
Lost and dangerous targets have the appropriate icon displayed at the top right, as
indicated in the lost target example below.
There are five tabs available for viewing; [SENSOR], [VOYAGE], [IDENTITY],
[SCALE] and [QUALITY]. Press
W
or
X
to change the tab currently displayed.
The selected target’s bearing ([BRG]), range ([RNG]), [MMSI] and [NAME] are dis-
played at the top of the screen regardless of the selected tab. For lost or dangerous
targets, the appropriate icon is displayed at the top right of the screen.
The information displayed on each tab varies, depending on the type of target select-
ed.
The tables on the following pages list each tab’s contents, along with a brief descrip-
tion.
