press to decrease ping speed. When it's set at the desired level, press

2. The Sensitivity Control Bar appears. Press to decrease sensitivity;
press to increase sensitivity. When it's set at the desired level, press

to 50 percent. When it's set at the desired level, press

When you boost ping speed and switch into HyperScroll, the width of
the FasTrack bar graph display doubles in width at the right side of the
screen. This allows you to better see the virtually instantaneous sonar
returns, just as you would on a flasher sonar unit. For more informa-
tion on FasTrack, see it's entry in this section.

This command is used to reset all features, options and settings to their
original factory defaults. This is useful when you have changed several
settings and want to return the unit to basic automatic operation.
