Program Operation
INTRODUCTION
This section contains detailed instructions
on how to program all of the machine's
features, retrieve MIS information, set prices,
and load and calibrate the coin tubes.
There are two operation modes that the
operator can access. The first mode is the
Diagnostic Mode, which is activated when
the door is opened. The Diagnostic Mode
will list recorded machine errors and allow
the operator to clear them from the system.
The second mode is the Service Mode,
through which the operator can program
the various machine functions and retrieve
MIS information.
In this manual, messages that appear on the
display will be shown in upper case letters
enclosed by quotation marks. The keys on
the selection panel used to program the
machine are enclosed in < > marks.

The following error messages will be
displayed during the Diagnostic Mode.
They will be displayed repetitively in
the following order until cleared or until
