• [SORT (DANGER)]: Press
X
to display and sort the [DANGEROUS TARGET
LIST] in range order.
Note:
When [SORT (DANGER)] is selected, all non-dangerous targets are hid-
den on the plotter display and the plotter screen is surrounded by a red box, as
shown in the figure below.
To show any targets which were hidden by this option, select [SORT (NOR-
MAL)] from the [FUNCTION] pop up window.
• [VIEW DETAIL]: Press the
ENT/ACK
key to open the [TARGET DETAIL]
screen.
• [NEW MSG]: Press
S
to open the text input window to create an AIS message
to send to the selected target.
• [NAME REQUEST]: Press
T
to send a name request to the target vessel’s AIS.
Note:
Name requests cannot be sent to the same target within a short period,
regardless of target. If you have requested the name of a target too soon after
the last request, the pop up message "CANNOT REQUEST NAME" appears.
Wait a short while before requesting the name again.
Note 1:
A target is declared a lost target under the conditions shown in the table be-
low. A target is erased from the screen seven minutes (For AIS-SART, 18 minutes)
after no signal is received from the target.
Note 2:
When a target is considered to be on a collision course, the audible alert
sounds (if active). Take suitable measures to avoid collision.
Note 3:
"DANGER" appears next to the target type when a target is considered to be
on a collision course. Further, when a target becomes a lost target, "LOST" appears
next to the target type.
