corresponding ARROW button has no
function. Pressing that button will result in
no adjustment and the “error” audible will
be heard. A solid ARROW symbol means
the corresponding ARROW button can be
used to affect the menu adjustment.
The ARROW buttons often can be used
when no menu is on-screen. In these situations, pressing the ARROW
button affects the function of the active (last-used) menu. This is a short-
cut to menu operation. The menu appears on-screen while the adjustment
is made and times out. A frequently used menu can be adjusted very
quickly using this technique.
After an adjustment is made to a menu function, the menu times out after
a few seconds and the unit returns to normal operation.
Menu Layout. All menus use the same basic layout. The heading at the top
describes the menu function. The UP ARROW and DOWN ARROW symbols
to the left of the menu indicate which buttons are available for adjustment.
In menus that have several possible settings, a range of adjustment indicator
shows the total range available and the current setting.
Within the menu are the options available. The selected option or current
setting is highlighted in the black box. If no adjustment is made, this is the
selected setting. Press an ARROW button while the menu is displayed to
select another option.
Several of the menus are multi-step. In some situations if an adjustment is
made, additional options become available for further adjustment. Examples
of these multi-step menus are Depth Range, Depth Alarm and Zoom. See
the detailed description of each function for further explanation.
