The ASP feature has two lev-
els - Low and High. If you have
high noise levels, try using the
“High” ASP setting. However,
if you are having trouble with
noise, we suggest that you

with the high ASP setting.
However, there are times
when you may want to turn the
ASP feature off. This allows

feature.
To change the ASP level, press the MENU key three times. Then press
the key next to the “ASP” label until the desired level is obtained. Press
the CLR key to exit this menu.
FISHTRACK™
When the X-70A 3D is in the

when the unit is turned on. To
turn the FishTrack™ feature
off, press the MENU key two

to the “FishTrack” label. This moves the check mark from the “ON” box to
the “OFF” box. To turn it on again, repeat the above steps.
