Programming
0 - Resetting to Factory Defaults
To reset to factory defaults, power off then press and hold the * key while powering up. S2 will beep twice and the
LED will glow orange. Release the * key and the S2 will be ready for one of the following options:
1) Presenting the “Add User Master Card” to S2’s Reader to add a new user
2) Presenting the “Delete User Master Card” to delete a current user
3) Presenting a blank EM card to replace an “Add User Master Card” or “Delete User Master Card”. In this
case the first blank card presented will become the new “Add User Master Card” and the second blank
card presented will become the new “Delete User Master Card”. The LED will flash Red confirming that S2
has been reset to factory defaults and new Master Cards added. If the new Master Cards are not presented
within 10 seconds S2 will resume User Operating Mode and the LED will glow steady Red
When resetting to factory defaults the user's information is still retained
