Depending on the default settings, the receiver is shipped with a locked or unlocked
front panel. You can lock or unlock the front panel using the front panel keypad.

front panel keypad and allow you to make changes to all the operating
parameters; however, if the keypad remains untouched for the duration of the
set timeout period (default is 60 seconds), the keypad will change back to the
Lock state unless you change the keypad state on the Admin Menu. Likewise
you can toggle the keypad lock state back using
SELECT and INFO at any time

information on front panel keypad buttons, see
Navigation/Selection Keypad (on

panel. For more information on lock level password, see Setup Menu: Admin (on
page 71).
