Immediately turn off the power at the switchboard if the equipment is emitting smoke or fire. A heater can melt the equipment's power cord, which can cause fire or electrical shock. [. . . ] To distinguish real target echoes from sea clutter, echo average performs scan-to-scan correlation. Correlation is made by storing and averaging echo signals over successive picture frames. If an echo is solid and stable, it is presented in its normal intensity. Sea clutter is averaged over successive scans resulting in the reduced brilliance, making it easier to discriminate real targets from sea clutter. To properly use the echo average function, it is recommended to first suppress sea clutter with the A/C SEA control and then do the following: 1. If not displayed, press the [HIDE/SHOW] key to display the radar soft keys. OFF: LOW: No averaging Helps distinguish targets from sea clutter and suppresses brilliance of unstable echoes. The display shows EAV L, EAV M or EAV H when echo averaging is on. (a) Echo average OFF (b) Echo average ON Effect of echo averaging 4. RADAR OPERATION 3. 21 Outputting TLL Data Target position data can be output to NavNet equipment and shown on their plotter screens with the TTL mark ( X ) 1. If not displayed, press the [HIDE/SHOW] key to display the radar soft keys. Operate the cursor pad to place the cursor on the target whose position you wish to output. Press the TARGET soft key. . 125nm . 250/SP H-UP 319. 9°M TARGET TRAIL TLL OUTPUT ACQ TARGET INFO Requires ARP circuit board in Model 1800/1900 series NavNet radar. Not shown otherwise. RETURN + 359. 9°R 0. 240nm TARGET soft keys 4. The TTL mark appears on the plotter screen of the NavNet equipment at the target's position the moment the TLL OUTPUT soft key was pressed. Further, that position is recorded as a waypoint on all NavNet units, under the youngest empty waypoint number on each NavNet unit. Note: The screen of the TLL recipient may be temporarily interrupted when receiving TLL from another NavNet display unit. RADAR OPERATION 3. 22 Guard Alarm The guard alarm allows the operator to set the desired range and bearing for a guard zone. violate the guard zone, an audio alarm sounds and the offending target blinks to call the operator's attention. CAUTION · The alarm should not be relied upon as the sole means for detecting possible collision situations. · A/C SEA, A/C RAIN and GAIN controls should be properly adjusted to be sure the alarm system does not overlook target echoes. 3. 22. 1 Setting a guard alarm zone To set a guard alarm zone, set the radar to transmit and do the following: 1. Use the cursor pad to set the cursor on the top left corner (or top right corner) of the guard zone you want to set, then press the SET GUARD1 or SET GUARD2 soft key, depending on which guard zone you want to set. Use the cursor pad to set the cursor on the bottom right corner (or top left corner) of the guard zone area, then push the [ENTER] knob. Press RETURN soft key to finish. . 125nm . 250/SP H-UP 319. 9°M ALARM SET GUARD1 . 125nm . 250/SP H-UP 319. 9°M ALARM GUARD 1 SET GUARD1 ERASE GUARD1 SET GUARD2 1 SET GUARD2 2 RETURN RETURN MOVE +CURSOR TO ANOTHER CORNER OF GUARD1 AND PUSH KNOB TO SET. + 317. 2°R 0. 230nm E ALARM NO B LT V R M . 125n . 032nm m 39. 9°R +0. 230nm (1) Drag cursor to top (or bottom) corner for guard zone and press the SET GUARD1 or SET GUARD2 soft key.
