To  increase  a  brew  volume, 

place  the  ON/OFF

switch in the "ON" 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 re-
lease  the  switch  within  two  seconds  after  the  third
click causes the volume setting to be aborted and pre-
vious  volume  setting  will  remain  in  memory.)  Each
time the switch is pressed, two seconds 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 ON/OFF

switch  in  the  "ON"  position,  press  and  release  the
START switch once for every two-second interval to
be removed from the total brew time period; then im-
mediately press and hold down the START switch until
three clicks are heard. Release the switch. (Failure to
release the switch within two seconds after the third
click causes the volume setting to be aborted and pre-
vious volume setting will remain in memory). Allow
the brew cycle to finish in order to verify that the de-
sired 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 ON/OFF switch
in the "ON" 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 set-
ting to be aborted and previous volume setting will
remain in memory.)
View  the  level  of  the  liquid  being  dispensed.  When
the desired level is reached, turn the ON/OFF 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 pro-
cedure 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 prevent
any further programming until switch is once again
put into the "SET" position.
