DIGITAL BREW TIMER (Late Models)(cont.)

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 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 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.

NOTE - Brewers with half-batch option will have to be set for both full and half-batch settings.
