Deleting All User Badges Only
You can delete all of the User badges assigned to a specific
Master badge without deleting the Master badge itself.
Place the Master badge, originally used to add the Users, over
the reader window four (4) times in succession. You will hear a
beep each time and the blue light will flash.
Within 5 seconds, place ANY User badge over the reader
window.
ALL of the User badges are now deleted, but the Master badge
is still programmed.
