Backing Up Data
• Transcend does NOT take any responsibility for data loss or damage during
operation. If you decide to store data on your StoreJet 25 we strongly advise that you
regularly backup the data to a computer, or other storage medium.
• To ensure High-Speed USB 2.0 data transfer rates when using your StoreJet 25 with a
computer, please check that the computer has the relevant USB drivers. If you are
unsure about how to check this, please consult the computer or motherboard User’s
Manual for USB driver information.
Transporting
• Do not pack your StoreJet 25 into luggage without the proper padded support. Other
items in the luggage may damage your StoreJet 25 if it does not have the proper
protection.
• Avoid squeezing or compressing the StoreJet 25.
• Do not place objects on top of your StoreJet 25.
Power
• The SJ25H2 gets its power directly from your computer’s USB port. However, the power
supplied by the USB ports on some older computers does not meet the stable 5V DC
power requirements of the SH25H2. If your StoreJet does not function properly upon
connecting it to your computer, please plug BOTH ENDS of the USB 2.0 Y-cable into
your computer.

5
Both ends of the USB 2.0 Y-cable should
be connected to provide ample power to
the SH25H2
• Please use the Mini USB to USB A-Type cable that came with the StoreJet 25 to
connect it to a computer, and always ensure that the cable you are using is in good
condition. NEVER use a cable that is frayed or damaged.
• Ensure nothing is resting on the USB cable and that the cable is not located where it can
be tripped over or stepped on.
• If you have connected all ends of the USB cable and still have power-related problems
while reading / writing data, we recommend that you purchase a Transcend USB Power
Adapter (TS-PA2A) to provide the power necessary to operate the StoreJet 25.
Reminders
• Always follow the procedures in the “Disconnecting from a Computer” section to
remove the StoreJet from your computer.
