4.5. SINGLE BUTTON MENU INTERFACE
While LISTENING, the control button can be pressed to enter the menu interface. From the menu
system the user can configure several parameters which are discussed in this section.
When any menu screen is loaded the cursor will initially be located at the home position at the
top right corner next to the page number to indicate that the BACK action will occur when the
countdown expires.
Pressing the control button causes the CURSOR to move down to the next menu item and the
COUNTDOWN INDICATOR will be reset to 5. Once the CURSOR is pointing at the desired item
the user simply allows the COUNTDOWN INDICATOR to reach 0 and the selected item will be
executed. This simple behaviour is used throughout the menu interface to modify settings and
interact with the unit.
If the active menu has multiple pages, as indicated in the top right-hand corner then when the
last item is reached the next button press will load the next page and the cursor will return to
the home position. When the end of the last page is reached then the unit will loop back to page
1 of the active menu.
If the selected item is a menu then when the countdown expires the new menu is loaded,
otherwise if the item is an editable field then the display will go into edit mode to allow the value
to be changed. In edit mode the part of the field actively being edited is enclosed in a box to
highlight it. Some parameters will provide additional information on screen while editing such as
min and max values. All parameters are incremented by pressing the CONTROL BUTTON until
they are at the desired value. Allowing the COUNTDOWN INDICATOR to reach 0 either selects
the next editable digit in the field if there is one, otherwise edit mode will exit and the new value
will be saved.
If while editing a parameter value you wish to cancel the edit operation, then press and hold the
CONTROL BUTTON until the cursor returns to the home position.
If an item was selected accidentally then simply press and hold the CONTROL BUTTON until the
cursor returns to the home position or allow the COUNTDOWN INDICATOR to reach 0 without
pressing the CONTROL BUTTON.
The menu system is designed so that the unit will always return to LISTENING mode if the
CONTROL BUTTON is left released for a long enough time.
