Operating instructions
4-Port USB 2.0 Hub, switchable
Item no. 1608769
Intended use
This product serves to connect up to four additional USB devices. It has been designed to be
connected to a computer with USB interfaces. During operation it operates like a bi-directional
repeater, which repeats USB signals as required on upstream (computer) and downstream
(peripherals) cables. It is designed for USB 2.0 and backward compatible with USB 1.1. Its
operation requires connection with a computer. The product can be powered by an external
5 V/ DC power supply (not included).
It is intended for indoor use only. Do not use it outdoors. Contact with moisture, e.g. in
bathrooms, must be avoided under all circumstances.
For safety and approval purposes, you must not rebuild and/or modify this product. If you use
the product for purposes other than those described above, the product may be damaged.
In addition, improper use can cause hazards such as short circuiting, fire etc. Read the
instructions carefully and keep them. Make this product available to third parties only together
with its operating instructions.

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.
• The device is not a toy. Keep it out of the reach of children and pets.
• Do not leave packaging material lying around carelessly. This 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.
• 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
• Connect the cable's mini-B-plug with the corresponding port of your hub. Connect the
USB A-type plug to a vacant USB port of your PC. The hub is now operational.
• If required, switch each of the four ports on or off individually using the corresponding toggle
switches positioned on the hub top (I = On, O = Off).
The hub functions in "Bus-Powered-Mode". This means that the current of 500 mA
supplied by the computer via USB is divided among the 4 ports. The total current
consumption of all devices connected at any one time must not be higher than this
value.
• Alternatively, you can power the USB hub with an optional power supply. If an optional power
supply is used, then each port could be loaded with 500 mA.
You can connect up to 4 USB devices to the hub. The hub supports Plug & Play
and hot-swapping (device drivers are automatically recognized and the devices
themselves can be removed while the OS is running).
Tips and hints
• The USB 2.0 is USB 1.1-compatible. That means that traditional USB 1.1 devices can be
operated without problems on the USB 2.0 hub. USB 1.1 devices do not become quicker
through this! The USB 2.0 hub can, of course, also be operated on a USB 1.1 connection,
e.g. if your PC has no USB 2.0 connection. An increase in speed in the data transmission is
not possible here either. To be able to exploit the high speed (theoretically 480 MBit/s, i.e.
60 MByte/s), all devices must support USB 2.0 - the USB device (e.g. an external CD burner)
itself, the USB hub and the USB controller in the PC. In practical operation, the 480 MBit/s
are not achieved. Hardly any device (e.g. hard disk, burner etc.) is in a position to supply data
so quickly. Other causes also (e.g. simultaneous operation of other USB devices, protocol
information etc.) reduce the transmission rate.
• USB operation is not possible in Windows safe mode or under DOS. USB keyboards and
a USB mouse do not normally work. The BIOS/setup of your PC possibly has appropriate
support (could be called e.g. "Legacy USB support"). It is possible, however, that the USB
keyboard/mouse is to be connected directly to the motherboard and not on a USB hub.
Care and cleaning
• Disconnect the product from the power supply before cleaning.
• Do not use any aggressive cleaning agents, rubbing alcohol or other chemical solutions as
they can cause damage to the housing and malfunctioning.
• Clean the product with a dry, fiber-free cloth.
• Do not immerse the product in water.
Disposal
Electronic devices are recyclable waste and must not be disposed of in the
household waste. At the end of its service life, dispose of the product according to
the relevant statutory regulations.
You thus fulfil your statutory obligations and contribute to the protection of the
environment.
