Federal Communication Commission Interference 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 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 : To assure continued compliance, any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this equipment. (Example – use only shielded interface cables when connecting to computer or peripheral devices).
End Product Labeling
This transmitter module is authorized only for use in devices where the
antenna may be installed such that 0.5 cm may be maintained between the
antenna and users. The final end product must be labeled in visible area with
the following: “Contains FCC ID: 2ALHR012”
End Product Manual Information
The user manual for end users must include the following information in a
prominent location “IMPORTANT NOTE: To comply with FCC RF exposure compliance
requirements, the antenna used for this transmitter must be installed to
provide a separation distance of at least 0.5cm from all persons and must not
be colocated or operating in conjunction with any other antenna or
transmitter.” This device complies with part 15 of the FCC rules. Operation is
subject to the following two conditions
- This device may not cause harmful interference and
- This device must accept any interference received, including interference that may cause undesired operation.
IMPORTANT NOTE: In the event that these conditions can not be met (for example certain laptop configurations or colocation with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID can not be used on the final product. In these circumstances, the OEM integrator will be responsible for reevaluating the end product (including the transmitter) and obtaining a separate FCC authorization. This device is intended only for OEM integrators under the following conditions: The antenna must be installed such that 0.5 cm is maintained between the antenna and users. As long as a condition above is met, further transmitter test will not be required. However, the OEM integrator is still responsible for testing their end product for any additional compliance requirements required with this module installed (for example, digital device emissions, PC peripheral requirements, etc.).
FCC Radiation Exposure Statement
- This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 0.5 centimeters between the radiator and your body.
- This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
- The antennas used for this transmitter must be installed to provide a separation distance of at least 0.5 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter.
Industry Canada Statement
This device contains licence-exempt transmitter(s)/receiver(s) that comply
with Innovation, Science and Economic Development Canada’s licence-exempt
RSS(s). Operation is subject to the following two conditions:
- This device may not cause interference.
- This device must accept any interference, including interference that may cause undesired operation of the device.
The host product shall be properly labelled to identify the modules within the
host product.
The ISED certification label of a module shall be clearly visible at all times
when installed in the host product; otherwise, the host product must be
labelled to display the ISED certification number for the module, preceded by
the word “contains” or similar wording expressing the same meaning, as
follows: Contains IC : 22518-BT012
IC Radiation Exposure Statement
This equipment complies with RSS-102 radiation exposure limit set forth for an
uncontrolled environment. This equipment should be installed and operated with
minimum distance 0.5 cm between the radiator and your body.
