Ensure the brew basket is in place. Place a suitably graduated container in place below the brew basket to capture
and measure the water delivered. To calibrate, enter the service mode as noted above and advance to the "CAL"
screen. Press either the left or right brew button and water delivery will begin. If the brewer has not reached
operating temperature, it will finish heating before automatically starting. The pump will cycle on and off for
approximately 2 minutes at which time the currently programmed volume is displayed. Use the left and right button to
decrement or increment the value to the measured value. For better accuracy, you may want to measure a couple of
cycles and average the measured values. Note that user mode will be entered automatically when exiting the service
mode if calibration values have been changed.
Service Data consist of the tank temperature as measured at two points in the tank and an indication as to which
probe(s) are making contact with the water. To view data, enter the service mode as noted above and advance to
the "Srv" screen. Use the left or right button to enter service data mode. Use the center button to advance through
the data. The table below list the data that is displayed.

User Mode is entered by holding any of the buttons on the face of the machine while powering up the brewer. Note
that the user mode is also automatically entered whenever the calibration volume setting is changed. The beverage
volume, brew time, and visa-brew time can be programmed for each of the three buttons on the face of the brewer.
The brewer will determine the minimum brew time possible based on pump speed and calibration values as outlined
previously. This time is set as the default whenever calibration values are changed. The brew time can be extended
to lengthen the water delivery time to meet a specific beverage taste profile. The table below list the data displayed
and values available.
