The coffee dose adjustments are made by acting on the group keyboads with machine at rated pres- sure.

1Press the button E on the panel and hold it down for 8-10 seconds until water stops flowing from the dispensing unit and the led of the continuons button begins flashing.

2It is necessary to act as to make 1 or 2 cups in or- der to reach the correct coffee amount adjustment in the cup.

3Put the filter-holder (with ground coffee) on the left unit and the cup under the spout.

4Operate the selected button (i.e. button A for one small cup).

5One the required coffee amount in the cup has been reached, press the stop button E. Coffe will stop pouring and the microprocessor will store the dose.

6Press the continuous button E again; the led will go out and the machine will store the new quantity.

7Make the coffee and check the cup amount in order to check that programming is correct.

If some doses have to be changed (B-C-D), once at point 5 repeat the instructions in points 3-4-5 for each dose, remembering to use the filter-holder with relevant filter and freshly ground coffee.

Then carry out point 6 and repeat point 7 to check all changed doses.
