Setting of Filter setting1 only when A or B, Adjustment is enabled. 
Adjust the threshold of signal detection level. 
The smaller the value, to detect the low levels signal. 
The smaller the number, it can be expected to display a trend of more deep. 
But, The influence of noise and interference, 
There is a risk measurement error is large. 
 
Use the L8 position usually. 
 
(reference) 
By the set to 7, it can be expected to measure the few m deep. 
If the seven smaller configuration, Measurements of the deeper is unreliable.
