SENSITIVITY
The sensitivity controls the ability of the unit to pick up echoes. A low
sensitivity level excludes much of the bottom information, fish signals, and
other target information. High sensitivity levels enables you to see this
detail, but it can also clutter the screen
with many undesired signals. Typi-
cally, the best sensitivity level shows a
good solid bottom signal with Grayline
and some surface clutter.

When the it's in the Automatic mode,
the sensitivity is automatically adjusted
to keep a solid bottom signal displayed,
plus a little more. This gives it the
capability to show fish and other detail.

However, situations occur where it
becomes necessary to 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 MENU key, then press the up or down
arrow keys until the "SENS" menu appears as shown above.

The sensitivity menu has left and right arrows, plus a horizontal bar graph.
The graph gives a visual indication of the sensitivity level. The number to
the right of the bar graph shows the percentage of sensitivity in use.

To increase the sensitivity level, press the right arrow key. As you press
the key, the menu’s bar graph will grow wider and the percentage will
increase in value. You can also see the difference on the chart record as
it scrolls. When the sensitivity is at the desired level, release the key.

To decrease the sensitivity level, press the left arrow key. The bar graph
and percentage will decrease. When the sensitivity is at the desired level,
release the key. When you reach either the maximum or minimum limit, a
tone sounds.

To erase the menu, press the EXIT key.
