HDC II Programming Guide Introduction

THE DISPLAYS
The 10-character display performs two functions, and is referred to in this book
as "the display":
• It shows the customer's selection and how much credit is in the machine,
as well as the ready, service, and time of day messages.
• It provides information and feedback to the service person during mainte-
nance.
THE FUNCTION KEYS
The keys on the control panel can be used for up to three things:
OTHER KEYS
The MOVEMENT keys on the control panel let you move inside a mode, and
back and forth between modes.
These keys are your "legs", which let you move up and
down the list of tasks. They let you continue from one step
to the next in programming procedures.
This is your "activate" or "choose" key. It "opens a door" to
additional information and lets you begin a programming
task once you are inside of a mode. Sometimes, it is used as
a toggle switch to show you your choices during a program
-
ming task.
This key can be used before running a function, or to
choose “ALL” in a multiple selection.
This is your "end" key. Pressing it one or more times will
move you back to the start of the mode, or all the way back
to the standby message.
