FCC

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 of the following measures:

• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and the receiver.
• Connect the equipment to 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.

Caution:

• Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this equipment.
• 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.

Radiation Exposure Statement:

• This equipment complies with FCC/IC radiation exposure limits set forth for an uncontrolled environment.
• The module must be installed in the host device.
• This End equipment should be installed and operated with a minimum distance of 20cm centimeters between the radiator and your body.
• This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.

LE-LAN devices are restricted to indoor operation only in the band 5150-5250 MHz

1. the device for operation in the band 5150-5250 MHz is only for indoor use to reduce the potential for harmful interference to co-channel mobile satellite systems;
2. the maximum antenna gain permitted for devices in the bands 5250-5350 MHz and 5470-5725 MHz shall comply with the e.i.r.p. limit; and
3. the maximum antenna gain permitted for devices in the band 5725-5825 MHz shall comply with the e.i.r.p. limits specified for point-to-point and non-point-to-point operation as appropriate.

Integration instructions for host product manufacturers according to KDB 996369 D03 OEM Manual v01r01 Hangzhou Meari Technology Co., Ltd. is seeking limited modular approval for radio module Model: A880; FCC ID: 2AG7C-A880, IC: 25838-A880.

Information on test modes and additional testing requirements

The host manufacturer installed this modular with single modular approval should perform the test of radiated emission and spurious emission according to FCC part 15C, Part 15E, 15.209, 15.207, RSS-247, RSS-102, RSS-GEN requirements, only if the test result comply with FCC part 15C, Part 15E, 15.209, 15.207, RSS-247, RSS-102, RSS-GEN requirement, then the host can be sold legally.

Additional testing, Part 15 Subpart B &ICES-003 disclaimer

The host manufacturer is responsible for compliance of the host system with the module installed with all other applicable requirements for the system such as Part 15 B&ICES-003.

Note EMI Considerations

Host manufacturers installed this modular with single modular approval should be recommending “best practice” RF design engineering testing and evaluation in case non-linear interactions generate additional non-compliant limits due to module placement to host components or properties. Host manufacture- installed this modular with single modular approval should be recommended “For EMC/radio-parameter compliance purposes when an evaluation is done by the grantee or host provider (see Clause IX in KDB Publication 996369 D01& RSS- GEN, RSS-102) and there are no additional emissions generated due to simultaneous-transmission operations compared to single transmitter operations testing (i.e., not transmitting simultaneously), it is not necessary to file the additional simultaneous transmission test data. The host manufacturer is responsible for ensuring compliance with the applicable FCC&IC rules for the transmitters operating individually and simultaneously. This includes compliance for the summation of all emissions from all outputs occupying the same or overlapping frequency ranges, as defined by the applicable rules.

How to make changes:

Only the Grantee is permitted to make permissive changes. The Grantee may seek permissive changes to permit the use of the radio module within additional Meari host products following the same procedure as identified in 2.4. Each host product model will require AC Powerline Conducted Emissions, Spurious Radiated Emissions, and conducted output power verification. A C2PC will be completed for the integration into additional host models.

Additional testing, Part 15 Subpart B disclaimer

The modular transmitter is only FCC authorized for FCC Part 15 Subpart C 15.247 & 15.207 & 15.209 &RSS-247, RSS-102, RSS-GEN, and the host product manufacturer is responsible for compliance to any other FCC rules that apply to the host not covered by the modular transmitter grant of certification. If the grantee markets their product as being Part 15 Subpart B&ICES-003 compliant (when it also contains unintentional-radiator digital circuity), then the grantee shall provide a notice stating that the final host product still requires Part 15 Subpart B&ICES-003 compliance testing with the modular transmitter installed. Compliance with this device in all final host configurations is the responsibility of the Grantee. OEM integrators and end- users must be provided with specific operating instructions for satisfying RF exposure compliance. OEM integrators are instructed to ensure that the end- user has no manual instructions to remove or install the device
