To avoid using the wrong RFID card by accident we recommend that you cut the postcard along the dotted line in half as follows:
1) Black Card: RFID card will Roast Only (Green beans only)
2) White Card: The second RFID will Grind & Brew (Roasted beans only)
To use the card -- prepare the machine as you would normally by inserting your desired green beans into the roasting drawer (or with pre-roasted coffee if you wish to only Grind & Brew). Ensure that you do not use more than the recommended 80g limit of green coffee beans. Scan the card that corresponds to your desired function: Roast Only, or Grind & Brew Only.
You can use these cards to roast any beans you wish.
- Be very careful tonever use the grind & brew card with green beans! This breaks the machine instantly! (and can happen easily.)
- Beans Quantity: We suggest using about 3 tablespoons (45-50g) per roast. No more than 80g!
