The Key Lock function locks the temperature and parameter settings so that the tem-
perature and parameters cannot be changed by unauthorized persons. Authorized
personnel may use a code number to set, or release the Key Lock function. The code
number is not set before shipping. The code number can be set using any three-digit
number from 001 to 999. When the code number is set correctly, the number will flash 5
times. If an incorrect code number is input, the display will show ‘NG’, and return to the
initial display.
