narrow beam, it is located directly under your boat, and is displayed as a solid fish symbol. If a
target is seen in the wide beam only, it can be assumed that the target is at the outside of the
sonar coverage area, not directly under the boat, and is displayed as a hollow fish symbol.
CONTROL FUNCTIONS
The Wide View unit uses only seven buttons to control all functions. The controls are
divided into two groups: POWER, STOP, and LIGHT are one group, and the Menu System
controls are the other group. When any button is pressed, an audible "chirp" will verify the control
input.
POWER, as previously discussed, powers the Wide View 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 onscreen until STOP is pressed again. The digital
bottom depth will continue to update, as usual, even if the display is
stopped.
LIGHT enables a two-level display backlight and backlit keypad.
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 off.
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 on-screen 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 the limit alarm sounds.
DOWN arrow selects the next smaller adjustment within the menu.
ENTER is used to toggle other menu options on and off.
All menus use the same general layout as shown in the sample menu at the right. 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. With several exceptions, once a
setting has been changed, the Wide View will remember that setting until it is again changed,
even if power is disconnected.
