3. Conditions for re-use of modular certification
To make use of modular certification, product level MUST comply with ALL rules mentioned below. If
these conditions cannot be met, then the FCC authorization is no longer considered to be valid and
StreamUnlimited's FCC ID may not be used on the final product. In these circumstances the host
integrator is responsible for evaluating the final product and obtaining a separate FCC authorization.
1. ONLY antennas listed under section 4 are used.
Equivalent antennas of same type and of equal or lower gain and similar in-band and out-of-
band characteristics can be included in the modular certification.
Costs for compliance testing and formal approval process will need to be covered.
2. Antennas must be oriented orthogonally to each other and spaced at a minimum distance
of 18 cm [see “Antenna testing configuration” for detailed arrangement].
3. The antenna(s) used for this transmitter must not transmit simultaneously with any other
antenna or transmitter, except in accordance with FCC multi-transmitter product procedures.
4. All equipment shall be considered to operate in a “general population/uncontrolled”
environment.
5. In order to comply with SAR requirements, host integrator must ensure that the final device is
for mobile use and that the antennas are at least 20 cm from the end user.
6. The WiFi output power configurations which are stored in “NVRAM file” must remain
unchanged.
7. Regulatory domain is set to world-wide or set to “US”.
8. Regulatory domain configuration is not accessible for end-user (StreamSDK Software does not
allow such access).
9. The Bluetooth output power which is hard-coded in firmware to 6dB remains unchanged.
10. Product labelling requirements are met (see section 3.1).
11. Instructions for use requirements are met (see section 3.2).
12. The product is secured against tampering with the software via local access or by changing the
software update image.
Additional notes:
Ad 3):
The integrator should check for emissions that may occur due to the intermixing of
emissions with the other transmitters, digital circuitry, or due to physical properties of
the host product (enclosure). This investigation is especially important when
integrating multiple modular transmitters where the certification is based on testing
each of them in a stand-alone configuration. It is important to note that host product
manufacturers should not assume that because the modular transmitter is certified that they do not
have any responsibility for final product compliance.
