1.38 Target Alarm
The target alarm serves to alert the navigator to targets (ships, landmasses, etc.) en-
tering a specific area, with audiovisual alerts.
The target alarm zone has a fixed width
of 0.5 nm in the radial direction (depth)
and is adjustable from 3.0 to 6.0 nm (tar-
get alarm zone 1) and any distance (tar-
get alarm zone 2). On the non-IMO
radar the boundaries can be set at any
distance. On any radar type the sector
of the zone can be set from 0 to 360 de-
grees in any direction.
Note: The [ALR1] and [ALR2] 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].
1.38.1 How to set a target alarm
The procedure below shows how to set a target alarm using the figure below as an
example.
1. Place the cursor in the [ALR1] or [ALR2] box as appropriate, then press the left
button. The cursor jumps into the operational display area and the indication
"SET" appears inside the target alarm box selected.
2. Using the Touchpad, move the cursor to Point A, then press the left button.
3. Using the Touchpad, move the cursor to Point B, then press the left button.
“SET” is replaced with “WORK” in the [ALR1] box indication. 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.
CAUTIONCAUTION
The alarm should not be relied upon as the
sole means for detecting possible collision
situations.
A/C SEA, A/C RAIN and GAIN controls
should be properly adjusted to be sure the
alarm system does not overlook target
echoes.
