2. Labeling.
AdafruitIndustries BluetoothModule
Model number: Bluefruit
labeled as below.
NOTE: Host device must be labeled with:

FCC Regulatory Information. OEM device should contain labeling that:
Approved in accordance to FCC rules transmitter module marked by FCC ID:
S6OBLUEFRUIT, manufactured by CIXI INTEC ELECTRONIC CO., LTD. to OEM product.
When it’s not possible, user manual should include such information.
For example:
“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.” This device contains FCC ID: S6OBLUEFRUIT.
Bluetooth Module, model number: Bluefruit can be incorporated into many different devices.
The modules generally consist of a completely self-contained
radiofrequency transceiver missing only a power source to make
it functional. Once the modules are authorized by the
Commission under our certification procedure, they may be
incorporated into a number of mobile devices.The completed
product generally is not subject to requirements for further
certification by the FCC.
3. Other regulatory notes for OEM.
Modular transmitters save manufacturers the time and any related expenses that would be
incurred if a new equipment authorization were needed for the same transmitter when it is
installed in a new device. This means that it can be integrated into end products without
further testing or approval listing. The manufacturer must state the CIXI INTEC ELECTRONIC
CO., LTD. part number and product reference in his literature in order to meet the module
requirements and regulatory. This should be clearly indicated in the OEM manuals.
The purchaser / integrator (developer) must satisfy all relevant FCC, SAR, EMC and Radio
regulations which apply to their finished product. We believe such parties have the technical
competence to ensure that the systems they deploy continue to comply with all those rules.
It is illegal to use amplifiers or higher gain antennas with this module. Maximum supply
voltage allowed is 3.7Vdc
