FCC NOTE FOR MODULER STATMENT
1.1 List of applicable FCC rules:
The module complies with FCC Part 15.247.
1.2 Summarize the specific operational use conditions:
The module has been certified for Fix, Mobile, Portable applications.
This transmitter must not be co‐located or operating in conjunction with any other antenna or
transmitter.
1.3 Limited module procedures:
The module has not its own RF shielding, which belong to limited module Standard requires:
Clear and specific instructions describing the conditions, limitations and procedures for third‐parties
to use and/or integrate the module into a host device (see Comprehensive integration instructions
below).
Resolve: Supply example as follows:
Installation Notes:
1) nRF52810 Module Power supply range is DC 3.3V, when you use nRF52810 Module design
product, the power supply cannot exceed this range.
2) When connect nRF52810 Module to the host device, the host device must be power off.
3) Make sure the module pins correctly installed.
4) Make sure that the module does not allow users to replace or demolition.
1.4 Trace antenna designs:
Not applicable.
1.5 RF exposure considerations:
This equipment complies with FCC RF radiation exposure limits set forth for an
uncontrolled environment. The antenna(s) used for this transmitter must not
be collocated or operating in conjunction with any other antenna or transmitter.
Note: the host product manuals must include a statement in order to alert the users of FCC RF exposure
compliance.
1.6 Antennas
The antenna type is a dipole antenna, is permanently attached, can’t be replaced.
1.7 Label and compliance information
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.
Warning: Changes or modifications to this unit not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.

NOTE: 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 andused 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 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.
The system integrator must place an exterior label on the outside of the final product housing the
nRF52810 Modules. Below is the content that must be included on this label.
The host product Labeling Requirements:
NOTICE: The host product must make sure that FCC labeling requirements are met. This includes
clearly visible exterior label on the outside of the final product housing that displays the contents
shown in below:
Contains FCC ID:2A4AD-NRF52810
1.8 Information on test modes and additional testing requirements:
When testing host product, the host manufacture should follow FCC KDB Publication 996369 D04

product during the measurements. In setting up the configurations, if the pairing and call box options
for testing does not work, then the host product manufacturer should coordinate with the module
manufacturer for access to test mode software.
1.9 Additional testing, Part 15 Subpart B disclaimer:
The modular transmitter is only FCC authorized for the specific rule parts (FCC Part 15.247) list on the
grant, and that 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. The final host product
still requires Part 15 Subpart B compliance testing with the modular transmitter installed when contains
digital circuity.
1.10 Information on test modes and additional testing requirements:
When testing host product, the host manufacture should follow FCC KDB Publication 996369 D04
