The "F" button activates the code free (passage mode) entry feature, so if you require continuous free passage you will need to proceed as follows:
1. Enter your access code, but before depressing the lever press the "F" button.
2. You will now be able to rotate the handle freely without entering the code.
3. To cancel the free entry feature, press the "F" button followed by the "C" button and this will reset the unit.
The "F" disk/tumber is supplied in the box with the lock.
