    • Press the power button while simultaneously holding down the i button and the leftmost function button. The ID code registration mode will be established and the figures 1 to 6 will appear on the display.
    • Press the function buttons beneath "1 to 6" on the display to enter the four digit code.
    • Press the power button The ID code will be registered and the power will be turned OFF.
