󰴤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/insert-
ed 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 specications.
• 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 ash drive is being accessed.
󰴥 USB specications
• Conform to USB 1.1 standard
• Applicable devices *1���� Storage devices such as USB memory, USB hub, FDD and card reader
• Not-applicable devices��CD drive, DVD drive, MO drive, tape drive, etc.

• Applicable medium size �FD (oppy disk) 1.44MB, 720kB
Others (USB memory, etc.), 4.1MB ~ (2TB)
• Recognition of drives ��For external devices such as a USB device, the device which is recognized rst
is accessed. However, when a medium is connected to the built-in media slot, the
access to that medium will be given the highest priority. (Example: If a medium is in-
serted into the media slot even when the USB memory has already been connected
to the USB port, the medium will be accessed.)
• Restriction on connection � Max. 10 devices (When the number of storage devices connected to the sewing
machine has exceeded the maximum number, the 11th storage device and beyond
will not be recognized unless they are once disconnected and re-connected. )
• Consumption current ���The rated consumption current of the applicable USB devices is 500 mA at the maxi-
mum.
