shows a letter c with a random number in the t-display.
- While holding both keys pressed, set the t-display to 12, using the [+] or [-]-
keys and press the 'e'-key.
- The display will flash twice confirming acceptance of the access code.
- Release the keys and c12 will dissappear from the display. You are now in the
service mode
