AUTOMATIC
When the Ultra Classic is first turned
on, the Automatic feature is enabled.
This is indicated by the word “AUTO”
at the top of the screen. The Auto-
matic feature adjusts the sensitivity
and range so the bottom signal is
displayed in the lower half of the screen
at all times.
To turn Automatic off, first press the
MENU key, then press the up or down
arrow keys until the "AUTO" menu
appears. Press the left arrow key to switch to the manual mode. The letters
“Man” appear at the top of the screen, indicating the unit is in the manual
mode. To turn Automatic on, repeat the above steps to get the auto menu,
then press the right arrow key.
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 Ultra Classic is in the Auto-
matic mode, the sensitivity is auto-
matically adjusted to keep a solid bot-
tom 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.
