reduce sensitivity bias. By holding either ARROW button depressed, the unit will sequence through the
available settings until you release the button or the end of the adjustment range is reached. If additional
time is needed to study a menu, press and hold the MENU button and the menu will remain on-screen
indefinitely.
If a setting limit is reached, the ARROW symbol attached to the menu appears to be hollow which
indicates that the related button has no further function. Also, the audible "error" consisting of multiple
chirps will be heard.
After an adjustment is made, the menu disappears and the new sensitivity setting begins to affect new
sonar information as it flows on-screen. If additional adjustment is needed, the UP ARROW or DOWN
ARROW can be pressed without having to first press MENU.
The Sensitivity setting is remembered in memory after the unit is powered oft.
Depth Range
The Depth Range function controls the vertical distance displayed on
the graphic area of the display. There are 9 different depth ranges
available. The top of the range is always 0, or the surface of the water.
Ranges of 0-15', 0-30', 0-60', 0-120', 0-180', 0-240', 0-360', 0-.480', and
0-600' are available. The range which positions the bottom depiction
closest to the bottom of the graphic area of the display, will best utilize
the available display resolution.
The Wide Optic automatically adjusts the depth range depending on the
depth of the water. The unit tries to maintain the bottom depiction about
2/3 down the total range (for example, in 20' of water, the 0-30' range
would be selected). This provides the best display resolution and
therefore the best target separation possible.
The Depth Range can be adjusted manually. Press MENU repeatedly
until the Depth Range menu is visible. The two options available are
"Auto" (Factory Setting) and "Manual". Pressing the DOWN ARROW
enables "Manual" depth range control and an additional menu will
appear which allows the user to adjust the current depth range setting. If no further button is pressed, the
current depth range is selected as the desired range and the unit returns to normal operation.
Using "Manual" Depth Range control, the user can view sonar information from the area near the surface
in great detail. If a depth range other than the current range is desired, pressing the DOWN ARROW to
highlight "Adjust" will allow selection of one of the 9 available ranges. Simply press and hold the UP or
DOWN ARROW button to scan through the available options. If a setting limit is reached, the audible
"error" or multiple chirps will be heard and no further adjustment is allowed.
When "Manual" range is used, the unit no longer adjusts the Depth Range to the most appropriate range
for bottom display. Often, the bottom may not be visible onscreen. The digital depth readout always
determines the depth of the bottom, even if it is not visible on-screen.
When a Depth Range is selected manually and the Depth Range menu is still active (most recently used),
further adjustment of the depth range can be achieved by simply pressing the appropriate UP or DOWN
ARROW button. The button press will bring the Depth Range menu on-screen and allows immediate
adjustment of the range.
To return to "Automatic" Depth Range control, press the MENU button until the Depth Range menu
appears on-screen and use the UP ARROW to select AUTO. The Wide Optic returns to Automatic
operation.
Note: Depth Range is not remembered when the unit is powered off. At power up, the unit is always in
automatic depth range.
