Turning off the alarm
Pressing any key while the alarm is activated will turn the alarm off. However, since the alarm function
is still active the alarm may sound again.
To turn the alarm function off, set to “GZ OFF” as shown above.
Note:
To set the alarm detection level, select an appropriate level from “GZ LEVEL” in the Radar initial
settings menu. The level ranges from 1 to 7 such that as the level number increases, only targets
with large signal strengths are detected and weak echoes from small targets and sea surface
clutter are ignored.
7.4.15 Setting up the power save function (SLEEP)
This function allows for a 30 second burst of transmission at a predefined time interval. After
transmitting for 30 seconds the power save mode is entered where the screen is set to standby
(antenna rotation is halted), after which the Radar transmits for another 30 seconds. This process is
repeated in the same manner. If any key is pressed while in the power save mode the mode will be
terminated.
A practical example: With the alarm function set, the system routinely checks for any incoming
or outgoing targets to/from the alarm area at the predefined time intervals set up in the power
save function.
To set up the function:
(1) Display the soft menu (RADAR/PAGE1 (2)/R FUNC/NAV).
(2) If the ”SLEEP” key
is pressed, the SLEEP time settings menu is displayed.
(3) Using the up / down key or the control knob set up the SLEEP time.
