ENTERING SERVICE MODE
1. Install JP14 on the NCU (this step may not be necessary outside W.
Germany).
2. Press 1, 2, 3, *, 0, and # simultaneously.
EXITING SERVICE MODE
Remove JP14 from the NCU (this step is optional outside W.
Germany).
Also, the machine automatically exits service mode immediately after
you finish a function, unless you used the function for less than 5
minutes. In that case, the machine will remain in service mode for 5
minutes after you entered service mode.
Another way to enter service mode is to switch the machine off, wait a few seconds, then switch back on while
holding the Stop key down.
