•
Corrects sensitivity while the function mode is called.
•
Since the displayed noise level varies depending on the combination of the video process mode and
the interference rejection level, sensitivity needs fine adjustment for always obtaining the highest
level.
•
The sensitivity correction function saves the correction value set by the sensitivity control in each
function mode, so it can obtain the highest sensitivity without the sensitivity control being operated
when the function mode is changed.
•
To set high sensitivity, set a value on the “+” side.
•
To set low sensitivity, set a value on the “-” side.
•
When the radar interference rejection level is increased, the noise level is lowered. Thus, set a
sensitivity correction value to the “+” side.
•
When the video process mode 3SCAN CORR, 4SCAN CORR, or 5SCAN CORR is used, the noise
level is lowered. Thus, set a sensitivity correction value to the “+” side.
•
When the video process mode REMAIN or PEAK HOLD is used, noise is hard to disappear. Thus,
set a sensitivity correction value to the “-” side.

•
Same function as in the TRX Setting of the RADAR Menu generally used
[Page 5] [3] Small Buoy Detection
•
Reduces the loss of signal processing during detection of small targets.
OFF: Activates the general signal processing mode.
ON: Activates the small buoy detection mode that reduces the loss of signal processing.
[Page 5] [4] Fishnet Detection
•
Use this mode to detect small targets hidden by sea clutter returns.
•
This function becomes more effective when the AUTO RAIN clutter suppression function is used
together.
OFF: Activates the general signal processing mode.
ON: Activates the fishnet detection mode.
