① 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 operation. 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.
• When the panel displays the communication screen or pattern data list, the USB drive is not recog-
nized even if you insert a medium into the slot.
• For USB devices and media such as CF(TM) cards, only one device/medium should be basically
connected/inserted 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 specifications.
• Insert the USB connector into the USB terminal on the IP panel until it will go no further.
• Do not turn the power OFF while the data on the USB flash drive is being accessed.
