FCC/IC compliance

This device complies with Part 15 of the FCC Rules and with Industry Canada license-exempt RSS standard(s).
Any changes or modifications NOT explicitly APPROVED by Twig Com may cause the module to not comply with the FCC rules part 15 thus void the user’s authority to operate the equipment.

1.1 FCC compliance
NINA-W15 modules are for OEM integrations only. The endproduct will be professionally installed in such manner that only the authorized antennas can be used.
For NINA-W151, an external antenna connector (U.FL. connector) reference design is available and must be followed to comply with the NINA-W15 FCC/IC modular approval.
1.2 FCC statement
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 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 the 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

1.3 RF exposure statement
1.3.1 IC compliance
This equipment complies with the requirements of IC RSS-102 issue 5 radiation exposure limits set forth for an uncontrolled environment.
To ensure that the output power remains below the SAR evaluation Exemption limits defined in RSS-102 issue 5, customer applications integrating NINA-W151 must include a separation distance of at least 30 mm between the user (or bystander) and the antenna (or radiating element).
1.3.2 FCC compliance
This device complies with the FCC radiation exposure limits set forth for an uncontrolled environment.
To ensure that the output power remains below the SAR evaluation Exemption limits defined in SAR test exclusion limits in KDB 447498 D01v06, customer applications integrating NINA-W151 must include a separation distance of at least 25 mm between the
user (or bystander) and the antenna (or radiating element).
1.4. End-product user manual instructions
1.4.1 IC compliance
User manuals for license-exempt radio apparatus shall contain the following text, or an equivalent notice that shall be displayed in a conspicuous location, either in the user manual or on the device, or both:
This device complies with Industry Canada’s license-exempt RSSs.
Operation is subject to the following two conditions:
(1) This device may not cause interference; and
(2) This device must accept any interference, including interference that may cause undesired operation of the device.
Under Industry Canada regulations, this radio transmitter can only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its
gain should be chosen in such a way that the equivalent isotopically radiated power (e.i.r.p.) is not more than that is necessary for successful communication.
1.4.2 End-product labeling requirements
1.4.2.1 IC compliance
The host product shall be properly labelled to identify the modules within the host product.
The Innovation, Science and Economic Development Canada 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 Innovation, Science and Economic Development Canada certification number for the module, preceded by the word “Contains” or similar wording expressing the same meaning, as shown in Figure 1 Example of an end product label.

This device contains
FCC ID: 2A95KNINAW15
IC: 30482-NINAW15
Figure 1 Example of an end product label

1.4.2.2 FCC compliance
For an end product that uses the NINA-W151 there must be a label containing, at least, the information shown in Figure 1:
The label must be affixed on an exterior surface of the end product such that it will be visible upon inspection in compliance with the modular approval guidelines developed by the FCC.
In accordance with 47 CFR § 15.19, the end-product shall bear the following statement in a conspicuous location on the device:
“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.”
When the device is so small or for such use that it is not practicable to place the statement above on it, the information shall be placed in a prominent location in the instruction manual or pamphlet supplied to the user or, alternatively, shall be placed on the container in which the device is marketed.
In case, where the final product will be installed in locations where the end user is unable to see the FCC ID and/or this statement, the FCC ID and the statement shall also be included in the end product manual.

1.4.3 End product compliance
1.4.3.1 General requirements

• Any changes to hardware, hosts or co-location configuration may require new radiated emission and SAR evaluation and/or testing.
• The regulatory compliance of NINA-W151 does not exempt the end product from being evaluated against applicable regulatory demands; for example, FCC Part 15B criteria for unintentional radiators.
• Only authorized antenna(s) may be used.
• Any notification to the end user about how to install or remove the integrated radio module is NOT allowed.

1.4.3.2 Co-location (simultaneous transmission)
If the module is to be co-located with another transmitter, additional measurement for simultaneous transmission is required.

Antennas

This chapter gives an overview of the different external antennas that can be used together with the module.
This radio transmitter IC: 30482-NINAW15 has been approved by Industry Canada to operate with the antenna types listed below with the maximum permissible gain and required antenna impedance for each antenna type indicated. Antenna types not included in this list,having a gain greater than the maximum gain indicated for that type,are strictly prohibited for use with this device.
