2.22 Target Alarm
The target alarm looks for targets (ship, landmass, etc.) in the area you set.
Audiovisual alarms are released when a target enters (or exits) the alarm area.
2.22.1 How to set a target alarm zone
The following procedure shows you how to set a target alarm zone.
1. Press the TARGET ALARM key to activate ALARM 1 or ALARM 2.
Press the TARGET ALARM key again to change the active ALARM between No.
1 and No. 2.
The currently active ALARM is indicated in a rectangle at the upper-right corner of
the screen.
2. Use the cursorpad to move the cursor to the position A, then press the ENTER
key.
3. Move the cursor to the position B, then press the ENTER key. The rectangle that
shows alarm status indication at the upper-right corner of the screen disappears.
Note: To set a 360-degree guard zone, set the position B in the same bearing as the

Do not depend on the alarm as the only
means to detect possible collision
situations.
·
Adjust the A/C SEA, A/C RAIN and GAIN
controls correctly so that the alarm
system does not miss the target echoes.
