±2 for each brew cycle.

BREW VOLUME SET-UP:Use the following steps when the setting is unknown or a different circuit board is being installed.

1.Place an empty funnel in the funnel rails and an empty server or graduated vessel be- neath the funnel.

2.Place the "ON/OFF" switch in the "ON", upper position.

3.Press and hold the brew start button until you hear the brew solenoid click on-and-off three times (approximately 5 seconds). Re- lease the button.

4.Allow the cycle to continue until the desired amount of water is dispensed and then turn "OFF" the brewer.

The brewer is now set to dispense this amount of water for each subsequent brew cycle.

To increase the amount of water for each brew cycle place an empty funnel in the funnel rails and an empty server or graduated vessel beneath the funnel. Place the "ON/OFF" switch in the "ON", upper position. Press and hold the "BREW" switch until you hear the solenoid click on-and-off three times (approximately 5 sec- onds), then release the "BREW" switch. Momen- tarily press and release the "BREW" switch once for each ounce (approximate) of water to be added to the prior setting and allow the brew cycle to finish.
