Connecting USB devices
You can connect a USB device to your computer by inserting its USB plug
(Type A) into the USB port on your computer.
The first time you plug a USB device into a particular USB port on your
computer, Windows automatically installs a driver for that device. After the
driver has been installed, you can disconnect and reconnect the device
without performing any additional steps.
Before disconnecting a USB storage device, make sure your computer has
finished transferring data to that device. Click the Safely Remove Hardware
and Eject Media icon in the Windows notification area to remove the device
before disconnecting.
Note: Typically, Windows detects a new device after it has been connected, and then installs
the driver automatically. However, some devices may require you to install the driver
before connecting. Check the documentation provided by the device’s manufacturer
before connecting the device.
Note: If your USB device uses a power cord, connect the device to a power source before
connecting it. Otherwise, the device may not be recognized.

FCC Compliance Statement
2. The users manual or instruction manual for an intentional or unintentional radiator
shall caution the user that changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to operate the equipment. In
cases where the manual is provided only in a form other than paper, such as on a
computer disk or over the Internet, the information required by this section may be
included in the manual in that alternative form, provided the user can reasonably be
expected to have the capability to access information in that form.
3. CAUTION: Changes or modifications not expressly approved by the party responsible
for compliance could void the user's authority to operate the equipment.
4. NOTE: This equipment has been tested and found to comply with the limits for a Class
B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential installation.
This equipment generates, uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause harmful interference
to radio communications.
However, there is no guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:
-- Reorient or relocate the receiving antenna.
-- Increase the separation between the equipment and receiver.
-- Connect the equipment into an outlet on a circuit different from that to which the receiver
is connected.
-- Consult the dealer or an experienced radio/TV technician for help.
5,. This device has been tested and meets the FCC RF exposure guidelines.
The highest reported SAR values for body-worn accessory and simultaneous
transmission conditions are 1.144W/kg(1g) and 1.441W/kg(1g).
6. WARNING!! Read this information before using your phone
In August 1986 the Federal Communications Commission (FCC) of the United States
with its action in Report and Outer FCC 96-326 adopted an updated safety standard for
human exposure to radio frequency (RF) electromagnetic energy emitted by FCC
regulated transmitters. Those guidelines are consistent with the safety standard
previously set by both U.S. and international standards bodies. The design of this
1. This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions: (1) this device may not cause harmful interference, and (2) this
device must accept any interference received, including interference that may cause
undesired operation.
phone complies with the FCC guidelines and these international standards. Use only
the supplied or an approved antenna. Unauthorized antennas modifications, or
attachments could impair call quality, damage the phone, or result in violation of FCC
regulations. Do not use the phone with a damaged antenna. If a damaged antenna
comes into contact with the skin, a minor burn may result. Please contact your local
dealer for replacement antenna.
BODY-WORN OPERATION:
This device was tested for typical body-worn operations with the back of the phone kept
0cm from the body. To comply with FCC RF exposure requirements, a minimum
separation distance of 0cm must be maintained between the user's body and the back
of the phone, including the antenna, whether extended or retracted. Third-party
belt-clips, holsters and similar accessories containing metallic components shall not be
used. Body-worn accessories
that cannot maintain 0cm separation distance between the user’s body and the back of
the phone, and have not been tested for typical body-worn operations may not comply
with FCC RF exposure limits and should be avoided.
7. For more information about RF exposure, please visit the FCC website at www.fcc.gov
Your wireless handheld portable telephone is a low power radio transmitter and receiver.
When it is ON, it receives and also sends out radio frequency (RF) signals. In August,
1996, the Federal Communications Commissions (FCC) adopted RF exposure
guidelines with safety levels for hand-held wireless phones. Those guidelines are
consistent with the safety standards previously set by both U.S. and international
standards bodies:
Those standards were based on comprehensive and periodic evaluations of the
relevant scientific literature. For example, over 120 scientists, engineers, and
physicians from universities, government health agencies, and industry reviewed the
available body of research to develop the ANSI Standard (C95.1). Nevertheless, we
recommend that you use a hands-free kit with your phone (such as an earpiece or
headset) to avoid potential exposure to RF energy. The design of your phone complies
with the FCC guidelines (and those standards).
Use only the supplied or an approved replacement antenna. Unauthorized antennas,
modifications, or attachments could damage the phone and may violate FCC
regulations.

1. This device complies with Industry Canada licence-exempt RSS standard(s). Operation is
subject to the following two conditions: (1) this device may not cause interference, and (2) this
devicemust accept any interference, including interference that may cause undesired
operation of the device.
3.
This device has been tested for compliance with FCC RF Exposure (SAR) limits in typical
flat configurations.
In order to comply with SAR limits established in the RSS-102 & ANSI C95.1 standards, it is
recommended when using a Broadcom 802.11a/b/g/n/ac WLAN + Bluetooth 4.0 NGFF2230
Mini Card Combo module that the integrated antenna is positioned more than 0cm from your
body or nearby persons during extended periods of operation. If the antenna is positioned less
than 2.5cm from the user, it is recommended that the user limit the exposure time.
