Target Alarm

The target alarm serves to alert the navigator to targets (ships, landmasses, etc.) en-
tering a specific area, with audiovisual alerts.
The operator can set the alarm zones at
any location, with any size, however, the
zones must be inside the operational
display area.
Note: The target alarm boxes are not
displayed when the setting for [AZ/ALR
SELECT] in the [TT•AIS] menu is set to
the default setting [AQUISITION
ZONE]. To enable this function, set [AZ/
ALR SELECT] in the [TT•AIS] menu to [TARGET ALARM ZONE].

How to set a target alarm

The procedure below shows how to set a target alarm using the figure below as an
example. The alarm boxes are labeled [1:] and [2:], and are located at the bottom-right
of the screen, near the VRM boxes.
1. Select the appropriate alarm box, then left-click. The cursor jumps into the opera-
tional display area and the indication "SET" appears inside the target alarm box
selected.
2. Using the trackball, move the cursor to Point A, then left-click.
3. Using the trackball, move the cursor to Point B, then left-click.
The indication “SET” is replaced with “WORK” in the box. The target alarm zone’s
lines are shown as dashed lines.
Note 1: To create a 360° alarm zone, set Point B at the same location as Point A.
Note 2: Two alarm zones can be set simultaneously. The second alarm zone is only
available when the first alarm zone is active, however.
Note 3: When the target alarm zone is not within the range in use the indication "UP
RNG" appears to the right of the target alarm box. In this case select a range that will
display the target alarm zone.
