1.  OPERATION

The target alarm looks for targets (ship, landmass, etc.) in the area you set. When a 
target enters or exits the alarm area, audiovisual alarms are released.

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 to change the active ALARM between No. 1 and No. 2. The 
indication of the currently active ALARM is in a rectangle at the upper-right corner 
of the screen.

2. Use the CursorPad to move the cursor to the position A and press the ENTER 

key.

3. Move the cursor to the position B and press the ENTER key. The rectangle that 

shows alarm status indication at the upper-right corner of the screen disappears. 
(See figure below)

Note 1: To set a 360-degree guard zone, set the position B in the same bearing as the 
position A.

Note 2: When the target alarm zone is not within the range in use, the indica-
tion"ALM1(or 2)_RNG" replaces "ALM1(or 2)_IN(or OUT)" in the alarm status area. 
(When the target alarm zone is within the range of full off-centering, the indication 
does not change.) Select a range which displays the target alarm zone.
