Humminbird Wide Eye - Manual (Page 24)

POWER, as previously discussed, powers the Wide Eye for normal operation. Also,
if the unit is powered off, press and hold POWER until you hear a continuous "chirp" to enable
simulator operation as discussed in "Simulator Operation". Pressing POWER when the unit is in
normal or simulator operation will power the unit off.
STOP freezes the display to allow closer study. Pressing STOP again will resume normal
operation. Also, if a menu is on-screen, STOP will retain the menu on-screen until STOP is
pressed again.
The transmitted sonar signal travels downward, and is reflected back toward the surface by the
bottom or other objects for display on-screen. If a target is detected between the surface and the
bottom, it is displayed as a fish symbol. Depending on the strength of the signal reflected from the
object, one of three different size symbols is used. These reflected signals are "normalized" for
depth, so that a small fish does not appear to be a large fish if it is close to the boat.
LIGHT enables a two-level display backlight. Pressing once will turn the light on low, pressing a
second time will increase the backlight to the high setting, and pressing a third time will turn the
backlight oft.
The four remaining buttons work together to control the Menu System-an array of menu
controlled functions.
MENU brings a menu on-screen for adjustment, or if a menu is already present, the next menu in
sequence will appear. Menus will go off-screen and normal operation will resume after a short
period of time. If you wish to keep the menu onscreen for an extended period of time, press
STOP.
UP ARROW selects the next larger or next sequential adjustment within the menu. Holding an
Arrow button down will cause the unit to continue to make the adjustment, until a limit is reached,
and a continuous chirp is heard.
DOWN ARROW selects the next smaller adjustment within the menu.
ENTER is used to toggle other menu options on and oft.
All menus use the same general layout as shown in in the sample menu below. The heading of
the menu is at the top. The area in the center is controlled by the UP and DOWN ARROWS, and
the area under the horizontal line is controlled by the ENTER button. Not all menus are affected
by all controls, but the layout is the same regardless.
Pressing MENU repeatedly will sequentially display all available menus.
Menu Functions
The following section explains each menu in detail, and how
these adjustments can be used to extract the maximum
information from the sonar returns. Remember, once a setting
has been changed, the Wide Eye will remember that setting
until it is changed again, or until the unit is powered off.
Sensitivity
As the Wide Eye receives returned signals, the sensitivity of the
receiver is adjusted automatically based on a number of factors
such as the depth of the water, and the signal clarity. In murky
