TRAINING MANUAL

CONTROLS

The control panel features discrete buttons for each selection rather than
requiring the user to cycle through numerous choices to pick one.

A couple of buttons serve double functions. Pressing and holding RACK DRY will
turn the Child Lock ON or OFF. Pressing and holding CUSTOM PROGRAM will
store the customer’s favorite setting (one that is used most of the time.)

The main control board is located in the top of the machine rather than in the
front panel. The communication between the main control board and the control
panel is handled by a UART (Universal Asynchronous Receiver Transmitter) and
a 7-wire cable rather than by a 28-wire cable as in previous models. This
simplification is what makes it possible to have a re-locatable control panel.
