Important notes to third party user, host manufacturer for transceiver module
The transceiver Module complies with Part15 of the FCC rules and regulations. Compliance with the labeling requirements, FCC notices and antenna usage guidelines is required. To fulfill FCC Certification, the third-party user must comply with the following regulations:
- The third-party user must ensure that the text on the external label provided with this device is placed on the outside of the final product. Contains FCC ID: Q2O-CSR8675 (example) / IC: 152B-CSR8675 (example) .The enclosed 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.
- The transceiver Module may only be used with the antenna (internal, integral) that have been tested and approved for use with this module.
- The transmitter is certified as a module, it may be integrated or used inside another device (host). No further approval is required when the module is used in accordance with the FCC grant conditions, and any limitations or usage conditions required by the manufacturer’s instructions. Modifications not approved by grantee could void the user’s authority to operate the equipment.
- This device and its antenna must not be co-located or operating in conjunction with any other antenna or transmitter.
- Third party users, host manufacturer must test final product to comply with unintentional radiators before declaring compliance of their final product to Part 15 of the FCC Rules.
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.
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.
Warning: Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
Limited module procedures
Not Applicable.
Trace Antenna Designs
Not Applicable.
RF exposure considerations
- The module has been certified for Mobile applications.
- End-user product Manual shall contain below RF exposure statements.
