• Connect the USB cable by inserting the connector firmly into the USB connector.
• When connecting multiple devices using USB hubs, connect the WT3000 to the USB
hub that is closest to the controller.
• Do not connect or disconnect the USB cable after the power is turned ON until the
WT3000 boots up completely (until the WT3000 is ready for operation, approximately
20 to 30 s). If you do, the WT3000 may malfunction.
