Furuno 1943C-BB, FURUNO MARINE RADAR manual When the alarm is violated…, Canceling the guard alarm

Page 62

2. RADAR OPERATION

The equipment then searches for targets inside the guard zone to determine guard alarm type. If a target is found inside the guard zone, the guard zone type becomes an “Outward guard alarm,” and any target exiting the guard zone will trigger the audio alarm. If no target is found, the guard zone type becomes an “Inward guard alarm,” and any targets entering the guard zone will trigger the audio alarm. The guard alarm type is shown as G1(G2) IN or G1(G2) OUT.

Note 1: When the radar range is less than the guard zone range, G1 (G2) IN or G1 (G2) OUT is changed to G1 (G2) ***.

Note 2: If the network radar is set to standby while the guard alarm is active, the guard alarm is cancelled. The guard alarm is redisplayed when the radar is set to transmit again.

2.22.2When the alarm is violated…

Any radar target violating the guard zone will flash, the audio alarm sounds, and the alarm icon appears in red. Additionally the message “TARGET ENTERED INTO GUARD1(GUARD2)” or “TARGET LEFT FROM GUARD1(GUARD2)” is displayed at the bottom of the screen. Press the [CLEAR] key to silence the alarm.

2.22.3Canceling the guard alarm

1.Press the [ALARM] key to show the ALARM menu.

2.Press the B:ERASE GUARD1 or D:ERASE GUARD2 soft key as appropriate.

3.Press the E:RETURN soft key to finish.
