Fresh-Trac Transmitter
These instructions will explain the operation and maintenance of the Fresh-Trac coffee timer. This timer will
allow the user to track the freshness of coffee brewed into glass decanters. Fresh-Trac is only available
with Curtis Alpha G3 brewers. The Fresh-Trac decanter is dish-washer safe. The expected battery life in
the light unit is two years. The battery is not replaceable.
The Fresh-Trac timer uses 3 LEDs (Red, Yellow & Green), as a
visual time indicator.
The Red LED ashes 5 times at the beginning of the brew cycle
and the warmer plate will turn on.
The Green LED will ash every 3 to 5 seconds during the brew
cycle and continue until 25 minutes have elapsed.
At 25 minutes, the Yellow LED will ash every 3 to 5 seconds, for
5 minutes. This will continue for 5 minutes until 30 minutes has
elapsed.
At 30 minutes, the Red LED will ash every 3 to 5 seconds until 60 minutes have elapsed. The Red LED
indicates that the hold time has expired and any remaining coffee should be discarded.
All ashing LEDs will stop and the warmer will turn off completely after 60 minutes. A new brew cycle will
restart the Fresh-Trac timer.
