The up and down arrow buttons set the combination number from 0 to 999. "0" is not a
valid combination.
If a combination of 0 is selected and the
SYSTEM
key is pressed, the menu will be
exited and keypad lockout will not be evoked. If 1 to 999 is selected and the
SYSTEM
key is pressed again, the combination is locked into non-volatile memory and the menu is
exited. The lock icon (to designate keypad locked with a valid combination) will display
when the menu is exited. The
SYSTEM
key will operate for 10 seconds after the menu
mode is exited to allow the user to change the mode from OFF to the desired system
mode.
While the keypad is locked out, a simultaneous press of the up and down arrow buttons
enters the menu item from any mode instead of only OFF mode. When the menu is
entered with the keypad lockout feature enabled, the first menu item displayed is the
combination code 0. The up and down arrow buttons are used to set the combination
unlock number from 0 to 999. If the unlock number matches exactly with the
combination lock number stored in memory when the
SYSTEM
key is pressed, the
keypad is unlocked and the lock icon is removed. If the unlock number does not match
when the
SYSTEM
key is pressed, menu is exited and the keypad remains disabled.
