Clearing or Resetting the Reader
• If you’ve changed network related settings (address, master/remote status, etc.)
through the reader menus: The reader automatically resets itself when you leave the
menus. You’ll see a message that tells you that the reader is resetting if this is needed.
• If you’ve changed DIP switches: You must reset the reader for the changes to take
effect. Just press the Reset button on the back of the reader. (Disconnecting the power
and then connecting it again would do the same thing.)
• To erase the users in a reader while keeping its settings: Use the Clear Memory option
on the Security menu.
• To erase the reader’s settings while keeping the users in the reader: Do a warm boot;
this is explained below.
• To erase the reader’s settings and also erase all users: Do a cold boot; this is
explained below.
To erase all users from the reader while leaving the reader’s settings unchanged, use
Clear Memory on the Security menu; see
Erasing All Users from the Reader
starting
on page 52. To keep unauthorized people from erasing users, this option requires you to
have an authority level of 5 and to know the Security menu password; see
Why Setting
Authority Levels Is Critical
on page 16. If you don’t have access to the Security menu, you
can’t erase the users.

2. On the back of the reader, find the RESET and COLDBOOT buttons.
When the reader is upright, the COLDBOOT button is the top button and the Reset
