Normal audio quality operation will be recovered
when the strong electromagnetic field is no
longer present.
Ce produit n’est pas conçu pour
un fonctionnement dans de forts
champs électromagnétiques. Par
conséquent, la qualité sonore peut
diminuer si ce produit est exposé à
un fort champ életromagnétique. La qualité sonore
redeviendra normale après affaib-lissement du
champ électromagnétique.

Model 1117
7-Port USB Hub
System Contents
•
Model 1117 7-port USB Hub (with stand)
•
2.5’ USB cable for connection to a computer
•
User Manual
CAUTION
THIS USB HUB IS RATED TO ALLOW FOR 1.5 AMPS OF CURRENT
WHEN BUS-POWERED (WITHOUT ANY EXTERNAL POWER ADAPTER).
BEFORE CONNECTING ANY DEVICES TO THE USB HUB, ENSURE
THAT THE TOTAL MAXIMUM CURRENT DRAW OF EACH OF THE
DEVICES ADDED TOGETHER IS LESS THAN THE CURRENT RATING OF
THE USB HUB AND THE COMPUTER’S POWER SUPPLY. FAILURE TO
DO SO MAY DAMAGE THE PC, THE USB HUB, AND/OR ANY
DEVICES CONNECTED TO THE USB HUB.
IF YOU ARE USING A LARGE NUMBER OF DEVICES OR VERY
POWER-INTENSIVE USB DEVICES, AN EXTERNAL DC POWER
ADAPTER WITH A RATING OF UP TO 5V/3.5A MAY BE USED TO
PROVIDE ADDITIONAL CURRENT.
Setup & Operation
1.
Connect the square (Type “B”) connector of the
included USB cable to the USB hub.
2.
Connect the flat (Type “A”) connector of the cable to
one of the computer’s USB ports.
3.
The red power LED should light. The USB hub should
automatically be detected by the computer. Allow the
computer to completely install the device. It should
indicate when it has completed.
4.
You may now begin connecting devices to the hub
one at a time. Use the 7 USB ports on the USB hub as
you would the USB ports on the computer. The
computer may automatically detect connected devices
or it may require drivers for certain devices. Refer to the
instructions that come with those devices for support
regarding their installation.
Specifications and Features
• USB 2.0 and 1.1 compatible
• 7 device ports and one port for computer connection
• High-speed, Full-speed and Low-speed operation
• Bus-powered operation:
• Idle current: ~6 mA
• Operating current: ~250 mA
• Devices may use up to 1.5 Amps total current
• Self-powered with external power adapter (not included)
Troubleshooting
USB Hub does not work (Power LED not lit):
• Check the connection between the computer and hub
• Try connecting the hub to a different USB port on the
computer
One or more devices connected to the hub are
malfunctioning:
• If there are multiple devices connected to the hub, try
disconnecting the most recently connected devices until the
problem goes away
• Try restarting the computer, or reconnecting the USB hub
to the computer
• If too much power is being consumed by any of the
devices, you may need to use an external DC power adapter
to power the USB hub
The computer displays an error that the USB bus is
drawing too much current:
• You may need to use an external DC power adapter to
power the USB hub. The power adapter should be a
switching type with a rating of up to 5V/3.5A
