is shown with a narrow or no
gray line. A hard bottom returns a strong
signal which causes a wide
gray line.
It you have two signals of equal size, one with gray and the other
without, then the target with gray is the stronger signal. This helps
distinguish weeds from trees on the
bottom, or fish from structure.
GRAYLINE is adjustable. Since GRAYLINE shows the difference be-
tween strong and weak signals, adjusting Sensitivity may require a
different GRAYLINE level, also. The level chosen by the Z-9500 at
power
on is
usually adequate
for most conditions. Experiment with
your
unit to find the GRAYLINE
setting that's best for
you.
To adjust GRAYLINE, press the SENS key. The sensitivity menu
appears in the
upper
left side of the display, while the GRAYLINE label
appears immediately beneath it. Next, press the
key adjacent to the
"Gray."
label. This changes
the
sensitivity adjust menu to GRAYLINE
adjust and the GRAYLINE label to Sensitivity. Now press the key
adjacent to the up arrow to increase the GRAYLINE level Press the
key adjacent to the down arrow to decrease it. The number in the
menu's lower left corner
gives the current GRAYLINE level. The bar
chart also
gives a
graphical indication of the GRAYLINE level. You can
see the change on the screen (both on the menu and on the chart
record) as you press the keys. After you've made the adjustment,
press
the
key adjacent to the CLEAR label to erase the menu.
