1Precautions to be taken when handling USB devices
• Do not leave the USB device or USB cable connected to the USB port while the sewing machine is in opera-
tion. The machine vibration can damage the port section resulting in loss of data stored on the USB device or
breakage of the USB device or sewing machine.
• Do not insert/remove a USB device during reading/writing a program or sewing data.
It may cause data breakage or malfunction.
• When the storage space of a USB device is partitioned, only one partition is accessible.
• Some type of the USB device may not be properly recognized by this sewing machine.
•
JUKI does not compensate for loss of data stored on the USB device caused by using it with this sewing machine.
2 USB specications
• Conform to USB 1.1 standard
• Format supported _____FAT 32
• Consumption current ___
The rated consumption current of the applicable USB devices is 500 mA at the maximum.
