V - Model KN-8828B - Color LCD Display
Auto Coffee Roaster with Manual Control
The KN-8828B allows easy roasting of the coffee for new users, yet sup-
plies complete manual control for those who become advanced in their roasting
knowledge and are looking for a specifi c taste or roast level. Roast Profi les can
be saved for later use as well. Physically, it is the same as our other models. The
difference is the control panel and user interface.
In the Auto mode the user will fi nd that with just three pushes of the START button the coffee roast-
ing process will begin. In the manual mode, all parameters of the roasting process can be controlled by the
user. These modes and how to operate them are fully described in this chapter.

The fi rst thing that you will notice is the colorful LCD display panel. This is the interface between the
user and the roaster. Let’s begin by understanding what is displayed here. Detailed instructions on how to
use the various functions of the KN-8828B will be found on pages 14 through 17.
