16.6 Setting water hardness
The descale message is displayed after the appliance has been operated for a factory set period of time cal- culated on the basis of the maximum quantity of lime scale which may be contained in the water used. If nec- essary, this period of operation can be extended, making descaling less frequent, by programming the appli- ance based on the actual lime content in the water used. Proceed as follows:
•Remove the "Total Hardness Test" strip (enclosed on page 2) from its packaging then dip it fully in the water tank for a few seconds, Remove it and wait about 30 seconds (until it changes color and a num- ber of red squares are formed);
•Turn the appliance on by pressing the 
button (fig. 6).
•Press the MENU button (the light over the button comes on) then press the NEXT button repeatedly until the appliance displays:
WATER HARDNESS 4
•Press the CHANGE button repeatedly until the number coincides with the number of red squares on the test strip (for example, if there are 3 red squares on the test strip, press the button until WATER HARD- NESS 3 is displayed).
•Press the OK button to confirm the value. The coffee maker is now programmed to provide the descal- ing warning when necessary, based on the actual hardness of the water.
16.7 Resetting factory default settings
If you change the original values, the factory default values can be reset as follows:
•Press the MENU button (the light over the button comes on) then press the NEXT button repeatedly until the appliance displays:
RESET TO DEFAULT NO
• Press the CHANGE button and the appliance displays “RESET TO DEFAULT YES”;
•Press the OK button to reset the factory default values;
•The appliance is now reset to the factory default settings and the READY message is displayed.
17 CHANGING THE LANGUAGE
To change the language, press the CHANGE button for at least 5 seconds until the appliance displays the installation message in various languages. To select the required language, follow the instructions in section 4.1.
