Lowrance electronic X-55A SONAR User Manual


 
DIGITAL SONAR
When the X-55A is turned on for the first
time,
the
digital depth display
is
located
at the
top
left corner of the screen. This
display
comes from a
separate digital
sonar built into the unit. It
displays only
the bottom
depth.
If it loses the
bottom,
the last known
depth
will flash on the
display.
When
the
digital
finds the
bottom,
it will
automatically display
the bottom
depth
again.
The
digital
sonar can be turned
off,
however this also turns all automatic
features off
also,
such as auto
sensitivity,
auto
ranging,
and the Fish I.D.
feature.
