![Icom MR-1000T2 [21/47] Alarm function](/views2/1074677/page21/bg15.png)
The unit has an alarm function to protect your ship from collisions. If other ships or islands, etc. come into the pre-
programmed alarm zone, the function alerts you with an alarm. You can set the desired range and bearing for an
alarm zone. While the alarm function is activated, the power save function turns the CRT OFF until an alarm is
given, to conserve power.
■ Alarm zone setting
D Setting and using the alarm function
q Push [+]/[ ] or [–]/[ ] to select the desired
range.
w Push [Ω ≈ Ù Ú] to set the cursor to the starting
point of the alarm zone.
e Push and hold [ALM]/[ ] for 1 sec. to enter the
alarm zone setting.
• The starting zone appears on the screen. (Fig. 1)
r Push [Ω≈] to adjust an angle and push [Ù Ú] to
set the distance of the alarm zone.
• The selected alarm zone appears.
t Push [ALM]/[ ] to fix the alarm zone and activate
the alarm function.
•“ALM” appears on the bottom of the screen.
• The selected alarm zone remains.
y If a target comes into or goes out of the alarm zone,
an alarm beep is emitted.
• Push [ALM]/[ ] to cancel the alarm signal and func-
tion .
u To deactivate the alarm function, push [ALM]/[ ].
•“ALM” and alarm zone disappear from the screen.
i To activate the alarm function again with the same
programmed zone, push [ALM]/[ ].
•
“ALM” and pre-programmed alarm zone appears. (Fig. 2)
• Using the function with power saver
To activate the power save function, push and hold [TX
(SAVE)]/[ ] for 1 sec. while the alarm function
is turned ON.
• The CRT display turns OFF.
• When a target comes into the alarm zone, an alarm sig-
nal is emitted, the CRT display turns ON and the power
save function is cancelled.
■ Zone alarm setting
Zone alarm beep is emitted when the target comes
into the zone, or the target goes out of the zone. (p. 6)
q Push [MENU]/[ ] several times to call up the
FUNCTION menu.
w Push [Ú] until the “ZONE ALARM” section becomes
highlighted.
e Push [Ω ≈] to select IN or OUT
• IN : Alarm sounds when the target comes into the
zone. (see Fig. 3)
• OUT: Alarm sounds when the target goes out of the
zone.
Alarm sounds when the target
comes into the zone.

- Blind or shadow sectors may exist because of ob structions such as masts derricks or stacks an ob struction may throw either a complete or partial shadow as shown in the diagram below if a target is in a shadow sector target echoes may not appear on the screen 27
- D direction resolution 27
- D distance resolution 27
- I blind and shadow sectors 27
- I target resolution 27
- Target resolution is determined by the horizontal beam width and transmit pulse width sometimes it is difficult to detect two targets which are separated by short dis tances or which are in the same direction 27
- When tall and massive targets such as a large island are located at close range also shadowed without pro ducing any echoes this phenomenon is called blind sector it is very important to know the bearings and widths of all shadow sectors caused by your own ship s obstructions 27
- When two targets are not separated by more than the horizontal beam width they appear as one echo 27
- When two targets are not separated by more than the pulse width they appear as 1 echo 27
- When two targets are separated by more than the horizontal beam width they appear as two echoes 27
