1. Modifying brew volumes. To modify a brew vol-

ume, first check that the SET/LOCK switch is in the

“SET” position on the circuit board.

To increase a brew volume, place the TEA/OFF/

COFFEE switch in the “COFFEE” position, press and

hold the START switch until three clicks are heard.

Release the switch and press it again one or more

times. (Failure to release the switch within two sec-

onds after the third click causes the volume setting to

be aborted and previous volume setting will remain in

memory.) Each time the switch is pressed, two sec-

onds are added to the brew time period. Allow the

brew cycle to finish in order to verify that the desired

volume has been achieved.

To decrease a brew volume, place the TEA/OFF/

COFFEE switch in the “COFFEE” position, press and

release the START switch once for every two-second

interval to be removed from the total brew time pe-

riod; then immediately press and hold down the START

switch until three clicks are heard. Release the switch.

(Failure to release the switch within two seconds af-

ter the third click causes the volume setting to be

aborted and previous volume setting will remain in

memory). Allow the brew cycle to finish in order to

verify that the desired volume has been achieved.

2. Setting brew volumes. To set a brew volume,

first check that the SET/LOCK switch is in the “SET”

position on the circuit board. Place the TEA/OFF/COF-

FEE switch in the “COFFEE” position, press and hold

the START switch until three distinct clicks are heard

and then release the switch. (Failure to release the

switch within two seconds after the third click causes

the volume setting to be aborted and previous vol-

10510 071000

ume setting will remain in memory.)

View the level of the liquid being dispensed. When

the desired level is reached, turn the TEA/OFF/COF-

FEE switch to “OFF”.

NOTE: Several ounces of water will continue to sy-

phon from the tank after turning the switch “OFF”.

The brewer remembers this volume and will continue

to brew batches of this size until the volume setting

procedure is repeated.

NOTE: When brewing coffee, volume will decrease due

to absorption by the coffee grounds.

3. Setting programming disable feature. If it be-

comes necessary to prevent anyone from changing

brew time once programmed, you can set the SET/

LOCK switch to the “LOCK” position. This will pre-

vent any further programming until switch is once

again put into the “SET” position.
