Try a master reset CHAPTER 3. MASTER RESET AND PROGRAM RESET The SRV key is used for performing entries in the SRV mode. A MASTER RESET clears the entire memory and resumes initial values. A PROGRAM RESET resumes the initial program without clearing the memory. There are 2 kinds of MASTER RESET operations. MASTER RESET 1: Normal MASTER RESET Clears the entire memory and resumes initial values. MASTER RESET 2: It enables the layout of fixed keys in addition to MASTER RESET 1. Fixed keys: [0] [1] [2] [3] [4] [5] [6] [7] [8] [9] 1.
