Caution
Never insert one of the adapters into the power
socket without first attaching the power unit. This
could give you an electric shock if you touch the
contacts.
Press the adapter on to the power unit until it clicks into place. Make sure that the adapter is
properly attached by trying to push it out again. When you hear it click into place and it cannot
be moved any more, it is properly attached.
The optional components, thermal printer and barcode reader, are connected to the two IO
ports (6) and (7) on the side of the reader. Both devices can be connected at the same time
and can be plugged into either each of the ports. You will find more information about these
two components in Section 3.6.
On the bottom of the device you will find a diagram of the connections and the keypad.
