Precautions 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 ma-
chine.
• When the panel displays the communication screen or pattern data list, the USB drive is not recognized even
if you insert a medium into the slot.
• For USB devices and media such as CF cards, only one device/medium should be basically connected/in-
serted to/into the sewing machine. When two or more devices/media are connected/inserted, the machine will
only recognize one of them. Refer to the USB specications.
