Note: This device complies with Industry Canada’s license-exempt RSSs. Operation is subject to the following two conditions:
- This device may not cause interference; and
- This device must accept any interference, including interference that may cause undesired operation of the device.”
Caution: Changes or modifications not expressly approved by the manufacturer could void the user’s authority to operate the equipment.
To comply with FCC RF exposure requirements, the device and the antenna for this device must be installed to ensure a minimum separation distance of 20 cm or more from a person’s body. Other operating configurations should be avoided.
List of Applicable FCC Rules
-
The modular transmitter must have its own RF shielding. This is intended to ensure that the module does not have to rely upon the shielding provided by the device into which it is installed in order for all modular transmitter emissions to comply with Part 15 limits. It is also intended to prevent coupling between the RF circuitry of the module and any wires or circuits in the device into which the module is installed. Such coupling may result in non-compliant operation.
There is an RF shield covering the complete radio section of the Mesh Stamp® -
The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with Part 15 requirements under conditions of excessive data rates or over-modulation. No modulation / data inputs are provided.
The Mesh Stamp® 3 processor directly interfaces with the radio section. The processor controls the data rate and FSK frequency deviation ensuring excessive data rates or over-modulation cannot occur. -
The modular transmitter must have its own power supply regulation. This is intended to ensure that the module will comply with Part 15 requirements regardless of the design of the power supplying circuitry in the device into which the module is installed.
The Mesh Stamp® is powered by an input DC voltage of 3.6V to 7.0V. Linear regulators provide 3.3V to the processor section and radio chip. A linear regulator supplies 3.5V to the radio power amplifier. -
The modular transmitter must comply with the antenna requirements of Section 15.203 and 15.204(c). The antenna must either be permanently attached or employ a “unique” antenna coupler (at all connections between the module and the antenna, RF Section Shield Reverse Polarity SMA Antenna Connector including the cable). Any antenna used with the module must be approved with the module, either at the time of initial authorization or through a Class II permissive change. The “professional installation” provision of Section 15.203 may not be applied to modules.
A unique antenna coupler, a reverse polarity SMA connector, is attached to the Mesh Stamp® 3. Compliance testing was performed with a 8.0 dBi gain vertical antenna. -
The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing. This is intended to demonstrate that the module is capable of complying with Part 15 emission limits regardless of the device into which it is eventually installed. Unless the transmitter module will be battery powered, it must comply with the AC line conducted requirements found in Section 15.207. AC or DC power lines and data input/output lines connected to the module must not contain ferrites, unless they will be marketed with the module (see Section 15.27(a)). The length of these lines shall be length typical of actual use or, if that length is unknown, at least 10 centimeters to insure that there is no coupling between the case of the module and supporting equipment. Any accessories, peripherals, or support equipment connected to the module during testing shall be unmodified or commercially available (see Section 15.31(i)).
The Mesh Stamp® 3 was tested for compliance plugged into a mother board which provided power and a computer USB connection. The USB connection provided a method to communicate with the Mesh Stamp® 3 to instruct it to transmit on specific frequencies for compliance testing. The mother board is typical of ones which will be used for products incorporating the Mesh Stamp® 3. The mother board was not housed in an enclosure. -
The modular transmitter must be labeled with its own FCC ID number, and, if the FCC is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following: “Contains Transmitter Module FCC ID: XYZMODEL1” or “Contains FCC ID: XYZMODEL1.” Any similar wording that expresses the same meaning may be used. The Grantee may either provide such a label, an example of which must be included in the application for equipment authorization, or, must provide adequate instructions along with the module which explain this requirement. In the latter case, a copy of these instructions must be included in the application for equipment authorization.
The Mesh Stamp® has a silkscreened label containing the FCC ID number on its top side. A separate document showing the location of the FCC ID on the MS3 is included with the application. In addition, products manufactured by Zenner USA incorporating the Mesh Stamp® 3 contain an external label referring to the enclosed module. -
The modular transmitter must comply with any specific rule or operating requirements applicable to the transmitter and the manufacturer must provide adequate instructions along with the module to explain any such requirements. A copy of these instructions must be included in the application for equipment authorization. For example, there are very strict operational and timing requirements that must be met before a transmitter is authorized for operation under Section 15.231. For instance, data transmission is prohibited, except for operation under Section 15.231(e), in which case there are separate field strength level and timing requirements. Compliance with these requirements must be assured.
15.231 is not applicable to the Mesh Stamp® 3. -
The modular transmitter must comply with any applicable RF exposure requirements. For example, FCC Rules in Sections 2.1091, 2.1093 and specific Sections of Part 15, including 15.319(i), 15.407(f), 15.253(f) and 15.255(g), require that Unlicensed PCS, UNII and millimeter wave devices perform routine environmental evaluation for RF exposure to demonstrate compliance. In addition, spread spectrum transmitters operating under Section 15.247 are required to address RF Exposure compliance in accordance with Section 15.247(b)(4). Modular transmitters approved under other Sections of Part 15, when necessary, may also need to address certain RF Exposure concerns, typically by providing specific installation and operating instructions for users, installers and other interested parties to ensure compliance.
Specific instructions for RF exposure are addressed in the user’s guide provided for the end products containing the Mesh Stamp® 3.
