Section 6 - Service Keypad Functions
The COTI machines are fitted with a service keypad mounted on the rear of the door. It
enables the Operator to carry out specific functions during routine cleaning and
maintenance.
Note: During certain operations e.g. View Counters it is necessary for the operator to utilise
the screen mounted on the front of the door to view the data.
