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
Module Integration Guide for testing the host products. The host manufacturer may operate their
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
Module Integration Guide for testing the host products. The host manufacturer may operate their
product during the measurements.
