alter or modify various functions of the dispenser. This allows for precise dispensing of various flavors of
powdered products.
Programming of dispenser is achieved by entering a certain function, then, by use of programming
switches, the operator can customize the dispensing process to their specifications.
To access the programming mode, and to scroll through different function screens, the programming
switches shown are used. There are five switches that will be used for setup of the dispenser.
