that ‘Trails’ (above) is activated and mode of orientation is TM.

GZ
(Guard Zone alarm) –
The use of the Guard zone feature built
into the radar can detect approaching vessels entering your guard
zone. You can use the guard zone while you are moving or when
anchored to protect you in a full 360 degrees. The audio alarm can be
sounded from the unit or through an external speaker/buzzer wired
into the system – see Electrical connections in Installation manual.
In Head Up mode the GZ relates to the vessel and in North Up or
Course Up it relates to geographic north.
Define the guard zone by means of the EBL and VRM markers:
1. Press the [EBL] key and move cursor (EBL-VRM1) to make the
left side and top of the guard zone.
2. Press [ENT], [2] and move cursor (EBL-VRM2) to make the right
side and bottom of the guard zone. The guard zone will be gener-
ated clockwise from EBL1 to EBL2.
3. Press [ADJ] and move cursor to the GZ line. Use the [+] key to
toggle between: IN / OUT / OFF.
IN
= the alarm will be activated if any target enters the defined
guard zone.
OUT
= the alarm will be activated when all targets have left the
defined guard zone i.e. at least one target must be present inside
the GZ when the function is activated.
4. Press [ENT] to exit the control panel.
5. Press and hold [CLR] to clear the EBL-VRMs. This will give a
better view of the defined guard zone.
