FCC Statement
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.
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.
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.
FCC Caution:
Any Changes or modifications not expressly approved by the party
responsible for compliance could void the user‘s authority to operate the
equipment.
The antenna(s) used for this transmitter must not be co-located or
operating in conjunction with any other antenna or transmitter.
The country code selection is for non-US model only and is not available
to all US model. Per FCC regulation, all WiFi product marketed in US
must fixed to US operation channels only.
RF Exposure Information (SAR)
This device meets the government’s requirements for exposure to radio
waves.
This device is designed and manufactured not to exceed the emission
limits for exposure to radio frequency (RF) energy set by the Federal
Communications Commission of the U.S. Government.
The exposure standard for wireless device employs a unit of measure-
ment known as the Specific Absorption Rate, or SAR. The SAR limit set
by the FCC is 1.6W/kg. *Tests for SAR are conducted using standard
operating positions accepted by the FCC with the device transmitting at
its highest certified power level in all tested frequency bands. Although
the SAR is determined at the highest certified power level, the actual
SAR level of the device while operating can be well below the maximum
value. This is because the device is designed to operate at multiple
power levels so as to use only the poser required to reach the network.
In general, the closer you are to a wireless base station antenna, the
lower the power output.
While there may be differences between the SAR levels of various
devices and at various positions, they all meet the government
requirement.
For body worn operation, this device has been tested and meets the FCC
RF exposure guidelines for use with an accessory that contains no metal
and be positioned a minimum of 0cm from the body. Use of other
accessories may not ensure compliance with FCC RF exposure
guidelines. If you do not use a body-worn accessory and are not holding
the device at the ear, position the handset a minimum of 0cm from
your body when the device is switched on.
