Appendix A. Display Station Setup Instructions
It is the customer's responsibility to set up the display
station. If the customer requests setup aid, use these
instructions.
Before the display station is shipped from the factory, it
is fully tested and adjusted.
This setup procedure should be used after the display
station has been located where it is to be used; this
procedure should also be used whenever the display
station is disconnected and moved.
DANGER
The display station has a weight of approximately 34
kilograms (75 pounds). NEVER LIFT IT WITHOUT
AID.
If the display station has the Keylock feature, a small
envelope containing 2 keys is fastened to the machine.
Place the keys in a safe place; you will need one of
them later in these setup instructions.
Before you start the setup instructions, ensure that a
grounded power outlet is available: for the US, use 115
Vac; for World Trade, see the installation planning
representative.
If problems occur while you are following these
instructions, go to the Start of Call MAP.
The setup instructions are written in two sections:
• You can complete Section 1 without connecting the
display station to the system.
• Section 2 describes how to connect the display
station to the system.
