Technical Information

DGC 6xxx

Note:

If only the transmitting phase of the roast probe thermometer is to be
measured, it is not necessary to fill the coffee cup with water.
For a roast probe temperature test, the coffee cup

must

be filled with

water, because the test takes a long time.

5. Select a cooking program and set the roast probe temperature.
6. Switch the appliance on.

Note:

The MDU/ELP display reads:
Status: Signal OK
Transmission: Signal OK

7. If

Signal OK

is not displayed for the status and/or transmission,

check/test the individual components and replace them as necessary.
