Pass Codes

A Code 11 or 111 indicates there are no service codes recorded in that portion of the test, and system passes that portion of the test. If Code 11 or 111 is not received in KOEO SELF-TEST, codes received during KOER SELF-TEST may not be valid. It is very important that Code 11 or 111 (pass code) be observed in KOEO SELF-TEST. A Code 11-1-11 or 111-1-111 output during KOEO SELF-TEST indicates there is no KOEO code or Continuous Memory Code recorded. The separator code may appear as a 10 instead of a 1 on some test equipment.
