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.

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-

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.
