5.3.5 Automatic adjustment (AUTO)
"AUTO" adjusts the GAIN, STC and FTC automatically. If the "AUTO" key is pressed after
you've adjusted GAIN, STC, or FTC manually, they will all be switched to "AUTO" or harbor
mode (HBR). By pressing the "AUTO" key repeatedly, you alternate among the AT1, AT2
and HBR modes. By pressing "STC" key, all controls return to manual state.
AT1 Use when navigating in a harbor area, narrow channel, or area with small islands where
there is a high level of echo. The control condition is similar to turning down GAIN
slightly. *
AT2 Use on open sea to suppress sea clutter. The control condition is similar to high GAIN.
HBR Also for use when navigating in a harbor area, narrow channel, or area with small
islands. The FTC is switched to manual mode. The STC is set to a predetermined
value that you can select. See section 5.5.4.6.5 (7) "Setting Harbor STC".
* Manual FTC may be used in these modes to reduce the appearance of noise on the
screen.
You can make manual adjustments to GAIN and FTC during AUTO operation.
If the "GAIN" key is pressed, only GAIN enters the manual state.
If the "FTC" key is pressed, only FTC enters the manual state.
However, if the "STC" key is pressed, STC, GAIN, and FTC all enter the manual state.

To activate the Man Overboard function, press the "MOB" button at the lower right of the
display panel. This will send the boat's position to an external plotter through the NMEA
port using the "WPL" format. It will only work if you are connected to an external navigation
receiver and compass. You can then use the plotter to navigate a return to that position. To

of MOB and current position will be displayed on the screen. If you press the "MOB" key
while watching the MOB screen, MOB data will be cleared and you will return to previous
