When the Z-9500 is first turned
on,
the
display
will appear
similar to the
one on the
previous page. The
digital bottom
depth is
displayed
in the
upper
left corner of the screen. The word "AUTO" in the
upper center
of the
display indicates the sonar's automatic feature is on. A small
note symbol
next to the "AUTO" indicator means the alarm speaker is
enabled.
SONAR OPERATION
AUTOMATIC
When the Z-9500 is first turned on, the Automatic feature is enabled,
This is indicated
by the word "AUTO" at the
top of the screen. The
Automatic feature adjusts
the
sensitivity and range
so the bottom
signal
is
displayed
in the lower
portion
of the screen at all times.
To turn Automatic off, simply press
the AUTO key. The letters "Man"
appear, indicating the unit is in the manual mode. To turn Automatic
on, press the AUTO
key again.
SENSITIVITY
The
sensitivity key on the Z-9500 controls the
ability
of the unit to pick
up echoes. A low sensitivity level excludes much of the bottom infor-
mation, fish signals, and other target information. High sensitivity
levels enable you to see this detail,
but it can also clutter the screen
with noise. Typically, the best sensitivity level shows a good solid
bottom
signal
with Grayline®and some surface clutter.
When the Z-9500 is in the Automatic mode,
the
sensitivity
is automati-
cally adjusted to
keep
a solid bottom
signal displayed, plus a little more.
This
gives it the
capability
to show fish and other detail.
Sometimes ft becomes necessary to
manually
increase or
decrease the
sensitivity. This
typically happens when
you wish to see more
detail, so
an increase in sensitivity is indicated. The procedure
to adjust it is the
same whether the unit is in the automatic or manual mode.
To adjust the sensitivity, press
the SENS key.
