(a) MAIN ON/OFF SWITCH

This switch, located under the brewer behind the front leg, turns power on and off to all components in the brewer.

(b) BATCH SELECTOR SWITCHES

Pressing the switch corresponding to the Small, Medium, or Large batch selects the amount of coffee to be brewed. Pressing a different switch after a brew cycle has been initiated does not change the brew batch in progress. Light indicates the selected batch to brew.

(c) ON/OFF SWITCH (ENABLE BREW)

Pressing the ON/OFF switch alternately turns the brewer on and off. Pressing this switch during the brew cycle will interrupt the brew cycle, stopping the flow of water. Pressing this switch during the programming of the brewer will exit the setup and return to the main screen.

(d) BREW SWITCH

Momentarily pressing and releasing this switch begins a brew cycle.

(e) ® SWITCH

Pressing and holding the ® switch allows entry to the programming menus. Pressing and releasing the switch steps through each function screen during programming.

(f) FUNCTION SCREEN

This is the display which shows the various functions of the brewer and allows the programming to be ac- complished.

(g) FUNCTION SCREEN SWITCHES

These are the hidden switches which are used to program the brewer.

(h)FUNNEL SENSING COILS

This is used to "receive" information from the Smart Funnel handle (coffee name and batch size), and also

from RECIPE CARDS.

The upper left corner of the B in BUNN can be used to scroll backwards through the function list.
