CAUTION
 Always unplug the AC adapter from the printer before connecting the printer to a
Powered USB interface. Failure to do so may damage the host PC. For information
about installing a Powered USB interface, contact your Citizen Systems dealer.
 Check the orientation of the Powered USB cable connector before connecting it. Insert
it straight in so that the pins do not bend. Push it in until it clicks.
 When disconnecting the cable, always hold the connector.
 Be careful not to insert the USB interface cable into the cash drawer kick-out
connector.
 To connect more than one printer to a single computer via a USB interface you must change
the serial number of the USB interface.
 Hold the connector of the Ethernet interface cable perpendicular and straight when
connecting or disconnecting it. Doing it at an angle may cause the connector to
misconnect.
Use a serial interface cable with the connection layout shown below.
