Note: 1) When the lock mechanism is blocked (lock jammed) the knob must be turned/handle released, to release the lock mechanism.
Note: 2) The “Error in lock” indication is also shown instead of the POST flashes if the battery is
not accepted as new after a power-on-reset.
Some special LED indication schemes are used during lock maintenance actions:
