Furuno FEA-2107 Operator's Manual page 403

Setting conditions for viewing and logging of danger targets
The operator may set Closest Point of Arrival (CPA), Time for CPA (TCPA) and Log interval for viewing
dangerous ARPA and AIS targets on the ECDIS display. A dangerous ARPA or AIS target is blinking and its color
is green and red alternately. User can also alternatively log only information of a single chosen ARPA or AIS target.
Set desired limits for CPA, TCPA and log interval. Note that these limits are only for ECDIS; an ARPA radar has its
own setting for dangerous targets and thus a target which is dangerous at an ARPA display can be safe on the
ECDIS and vice versa. If an ARPA target is inside the CPA and TCPA, it is shown as a dangerous ARPA target on
the ECDIS display. Log interval defines time period for logging.
Note: The operator may choose logging of the track of a single AIS and/or ARPA target, if he chooses in the Log
Single Target window the desired number from the ARPA and/or AIS box. If this option is chosen, only information
of the target(s) selected is recorded.
Saving past track of a chosen ARPA or AIS target
To save past track of chosen ARPA or AIS target, do the following:
1. Find number of ARPA target or name of AIS target, by placing the cursor on the target and pushing the
thumbwheel.
2. Choose Settings from the Record menu and then open the Danger Targets page.
3. In the Log Single Target window, choose ARPA target number and/or AIS target name from the ARPA and
AIS boxes.
4. You can make a user chart from the danger target log. For further details see paragraph 23.3.8 "Making a user
chart from the log (past track)".
Note: By choosing a single target only the chosen target's information is recorded. If you want to record information
of all danger targets, remove selection from the boxes in the Log Single Target window.
1. Spin the thumbwheel to show Menu/Info/Chart Menu in the mouse
functions area and then push the left mouse button.
2. Choose Record from the menu and Settings from the submenu.
3. If the Danger Targets page is not already open, click the Danger Targets tab
to open it.
