Again press the START switch, and water will begin
dispensing into the container. The display shows a Brew
Time count at this time. When satisfied with the water
level, again press the START switch. At this point the
Brew Time flashes on the display for 20 seconds. Press
the START switch again within the 20 seconds to accept
the new Brew Time . No changes will be made if the
Brew Time is not confirmed in this last step.
There are four independent brew times in the unit. The

Brew Time is the cycle shown on the keypad. The
keypad cannot be modified while setting the brew
