menu disappears. If you want the menu to
remain on-screen longer press and hold
MENU—the menu will remain on-screen
indefinitely. Once you release the menu
button, the screen will time out. Once a menu
times out, it is still considered the active menu.
Press MENU to bring up the last menu used.
Arrow Keys. The UP ARROW and DOWN ARROW make
adjustments to menu functions. On the left side of every
menu there are UP ARROW and DOWN ARROW symbols.
The symbols indicate which ARROW button has a function
in a particular situation. Either one or both ARROW buttons
can be used to adjust the menu function. A hollow ARROW symbol means
the 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. An abbreviated
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.
