Status Of The Vessel Icon; Plots (Ais) - Icom MR-1210RII Instruction Manual

■ Status of the vessel icon

There are 5 kinds of target vessel status.
Sleeping target:
The AIS signal has been updated (received),
but the distance from your vessel is far, or you
set it as 'sleeping.' The target is displayed as
just a triangle without a heading or vector line.
Activated target:
The target is displayed with the heading line,
SOG (Speed Over Ground), COG (Course
Over Ground) vector and ROT (Rate of Turn).
Dangerous target:
Even if the target's status is sleeping or acti-
vated, when it enters your CPA and TCPA limit
settings, the target is displayed with a thick line
and changes its color to red.
Selected target:
The target information is displayed in the AIS
information box.
Lost target*:
When the AIS signal has not been updated
(received) for a specific time period, the target
triangle is marked with a red cross.
If the AIS signal has still not been updated (re-
ceived) for 6 minutes and 40 seconds, the tar-
get icon disappears.
* A vessel is regarded as a "Lost target" after a specified pe-
riod of time has passed since the vessel last transmitted
data. (p. 9)

■ Plots (AIS)

The plot displays the activated target, SAR, SART,
MOB, or EPIRB's past positions as 5 dots, during each
specified tracking interval.
• The target track may change, depending on the setting in
the "Track Interval" item of the Target menu. (p. 7)
