Tips and notes
• The USB 3.0 hub is USB 2.0/1.1 compatible. This means that common USB 2.0/1.1 devices can be operated
via the USB 3.0 hub without any problems. However, the USB 2.0/1.1 devices will not work any faster!
• To use the USB 3.0 hub at its full speed, all devices used must support USB 3.0: The USB device itself (i.e.
external hard drive), the USB hub and your computer’s USB controller.
• In practice, the theoretical maximum speed of USB 3.0 (or USB 2.0/1.1) is not reached. The reason for this
may include protocol information, simultaneous use of several USB devices or speed restrictions imposed by
the connected USB device or your USB controller/mainboard.
• In DOS or in Windows Safe Mode, USB operation is not possible. Depending on your computer or BIOS and
setup settings, you may nevertheless be able to use a USB keyboard or USB mouse. It may be necessary to
connect these devices directly to your computer’s USB ports and not to a USB hub.
• USB devices can be connected and disconnected during use. Your computer need not be turned off to
connect or disconnect devices.
• If data transfer is taking place via the USB port – i.e. if an external hard drive is transferring data to your
computer – and you disconnect the USB plug, your operating system may crash. This may also result in data
lost or damage to the file system of your external hard drive.
• In Windows® XP, Vista™, 7, 8 an arrow may appear in the menu bar when some devices are connected (i.e.
a USB hard drive). This function allows you to “disconnect“ the USB device from your computer. After that,
you can unplug the USB device without any danger.
• Always use appropriate USB 3.0 cables to connect USB 3.0 devices. Please note that the longer the USB 3.0
cable, the slower the data transfer rate may be.
Maintenance and cleaning
Never use any aggressive cleaning agents, rubbing alcohol or other chemical solutions to
clean the device, as they may attack the product housing and even impair its functioning.
• Disconnect the USB hub from your computer before cleaning.
• Never submerge the USB hub in water.
• Repairs and maintenance work may only be carried out by a professional or in a specialist workshop. There
are no components inside the product that you need to maintenance, never open/dismantle the product.
• To clean, use a dry, soft and clean cloth. Do not apply too much pressure to the housing to prevent scratches.
• Dust can be easily removed using a long-haired, soft and clean brush and a vacuum cleaner.

Safety instructions
Read the operating instructions carefully and especially observe the safety information. If
you do not follow the safety instructions and information on proper handling in this manual,
we assume no liability for any resulting personal injury or damage to property. Such cases
will invalidate the warranty/guarantee.
a) Persons / Product
• The product is intended for indoor use only. Do not use it outdoors. Contact with moisture, e.g. in
bathrooms, must be avoided under all circumstances.
• The entire product may not become moist or wet, never touch it with wet hands.
• Never use the product immediately after it has been brought from a cold room into a warm one.
The condensation generated could destroy the product. There is a risk of fatal injury due to electric
shock! Allow the product to reach room temperature before connecting and using it. This may
take several hours.
• When setting up the product, make sure that the cable is neither kinked nor pinched.
• The device is not a toy. Keep it out of the reach of children and pets.
• Do not leave packaging material lying around carelessly. These may become dangerous playing
material for children.
• Protect the product from extreme temperatures, direct sunlight, strong jolts, high humidity,
moisture, flammable gases, vapours and solvents.
• Do not place the product under any mechanical stress.
• If it is no longer possible to operate the product safely, take it out of operation and protect it from
any accidental use. Safe operation can no longer be guaranteed if the product:
- is visibly damaged,
- is no longer working properly,
- has been stored for extended periods in poor ambient conditions or
- has been subjected to any serious transport-related stresses.
• Please handle the product carefully. Jolts, impacts or a fall even from a low height can damage
the product.
• Also observe the safety and operating instructions of any other devices which are connected to
the product.
b) Miscellaneous
• Consult an expert when in doubt about operation, safety or connection of the device.
• Maintenance, modifications and repairs are to be performed exclusively by an expert or at a
qualified shop.
• If you have questions which remain unanswered by these operating instructions, contact our
technical support service or other technical personnel.
Operation
Make sure the total power input of all connected USB devices does not exceed 900 mA
(when connected to a USB 3.0 port of a computer) or 500 mA (when connected to a USB 2.0
port of a computer) respectively.
If necessary, connect an optionally available power adaptor (see “Technical data”) to the
DC socket next to the USB cable to supply higher output current per USB port.
1. If needed, attach the included rubber feet to the bottom of the USB hub. This ensures that the product is
stable and also serves to prevent damage to surfaces.
2. Connect the USB hub via its USB cable to a free USB 3.0 port on your computer. The computer does not
need to be turned off.
If your computer has no USB 3.0 port (i.e. on the mainboard or a USB 3.0 card), you can also
connect the product to a USB 2.0/1.1 port. Devices connected to the USB hub (both USB 2.0 or
USB 1.1) will work at normal USB 2.0/1.1 speeds.
The USB hub works in the so-called “bus powered mode”. This means that the power via the
computer to the USB hub is supplied to all four ports (according to the USB 3.0 standard 900 mA,
according to the USB 2.0 standard 500 mA).
This is sufficient for most mice or keyboards; however, many other devices may no longer function
correctly (for example, external 6.35 cm / 2.5“ hard drives, USB cameras, etc.).
Once the LED on top of the product lights up, the product is ready for use.
3. Windows will recognize the new hardware and install the drivers automatically.
4. Connect your USB devices to the USB hub.
