FCC STATEMENT
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.
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.
2）This device must accept any interference received, including interference that may cause
undesired operation.
Any changes or modifications not expressly approved by the party responsible for compliance
could void the user’s authority to operate the equipment.
Note: The manufacturer is not responsible for any radio or TV interference caused by
unauthorized modifications to this equipment. Such modifications could void the user’s authority
to operate the equipment.
FCC RF Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. End users must follow the specific operating instructions for satisfying RF
exposure compliance. This transmitter must not be co-located or operating in conjunction with
any other antenna or transmitter. This equipment has been SAR-evaluated for use in hand.
SAR measurements are based on a 5mm spacing from the body and that compliance is
achieved at that distance.
This device is restricted in indoor environment only.

CE Mark Warning
This is a class B product. In a domestic environment, this product may cause radio interference,
in which case the user may be required to take adequate measures.
RF Exposure Information
This device meets the EU requirements (1999/519/EC) on the limitation of exposure of the
general public to electromagnetic fields by way of health protection.
This device has been tested and meets the ICNIRP exposure guidelines and the European
Standard EN 62209-2. SAR is measured with this device at a separation of 0.5 cm to the body,
while transmitting at the highest certified output power level in all frequency bands of this device.
Carry this device at least 0.5 cm away from your body to ensure exposure levels remain at or
below the as-tested levels.
