Bypassing or Resetting the Access Code
Access Code
In order to enter the PROCESSOR’S internal diagnostic procedures, you must either enter the correct access code,
or know how to bypass or reset the access code in case the operator has changed the access code from the default
of 4-2-3-1. This procedure outlines both how to bypass and how to reset an access code.
The Service Bypass procedure allows you to access all processor functions without knowing or changing the access
code set by the operator.
The User Bypass procedure allows you to reset the access code to the default of 4-2-1-3 if the operator forgets the
new access code he or she has entered.
