independent of their variant-depending program load.

In the service function mode, the key S2 is ALWAYS
responsible for the function "LED test with integrated
2.

3. / 4.
... and switch on the appliance by ON/OFF switch S0.
For that keep the keys S1 and S3 pressed simultaneously
until the 3 confirmation LEDs LD1, LD2 and LD3 are flashing.
(A temporary flashing up of LEDs is possible and no fault!)
5.
By actuating the function key S2 you now can call the
function.
All LEDs and "188" in the display are flashing about 30 seconds.
Leaving the function / deletion of the fault memory
When all above-mentioned LEDs resp. the display have been
flashing for about 30 seconds, the function will be left
automatically.
All LEDs of the program and option keys are lit. The indication
in the display goes out. The appliance is in the "prestart"
mode again.
The function can be left even earlier by switching off the
appliance by ON/OFF key S0.
In any case, the service fault memory is deleted.
It is generally valid:
For calling all service functions you always have first
to actuate the function keys S1 and S3 before
switching on the appliance by ON/OFF switch S0.
The keys have to remain pressed about 4 seconds
to activate the function.
This procedure is intentionally different to that for the
customer functions.
