Navigation/Selection Keypad
Throughout this manual, there are references to parts of a keypad on the front of the
receiver. The navigation keys ( LEFT , RIGHT , UP , and DOWN ) and the SELECT key
are the primary controllers. Each navigation key performs various functions,
depending on the current state of the menu system (that is, sometimes the left
navigation key backspaces over an entry and sometimes moves the cursor to a
different menu item). Once the cursor is over the desired function, pressing the
SELECT (center key) key selects the current item. Pressing the SELECT key stores
any entered values.
The following is the Navigation/Selection keypad, which changes its function,
depending on the current state of the menu.
The following table shows which parts of this integral interface are being referenced
by which term.
