GEM3 Module Hardware Integration Guide Version 0.1 Example Reset Circuit ODULE AYOUT ONSIDERATIONS 1. Good: Place the module antenna side as close as possible to the board edge. Better: Allow the module antenna area to overhang the edge of the board by ~6.0mm. - Page 12 GEM3 Module Hardware Integration Guide Version 0.1 2. Good: Define a copper keepout area approx. 53mm x 20mm, 6mm in from module edge. Better: Increase the keepout area, starting at 6mm in from module edge. 3. Mechanical items (especially metal) should be kept as far as possible from the module antenna in all directions, including above and below the board surface.

ANADA The GEM3 module has modular approval for the United States and Canada. To ensure compliance when using the GEM3 module in a design, the OEM is required to adhere to the implementation considerations supplied in this hardware integration guide. -
Page 14: Fcc Warning
The OEM should have their device tested by a qualified test house to verify compliance with FCC Part 15 Subpart B limits for unintentional radiators. Any modifications to the GEM3 module could void the OEM’s authority to operate the equipment. - Page 15 Dans ces circonstances, l'intégrateur OEM sera chargé de réévaluer le produit final (y compris l'émetteur) et l'obtention d'une autorisation distincte au Canada. Le produit final doit être étiqueté dans un endroit visible avec l'inscription suivante: " GEM3 Module Contient des IC: 11922A- NPE105"...
- Page 16 North Pole Engineering declares under our sole responsibility that the essential radio tests have been carried out and that the GEM3 Module to which this declaration relates is in conformity with all applicable essential requirements of Directives 2014/53/EU and 2015/863/EU when used for its intended purpose.

8.3 B LUETOOTH UALIFICATION The GEM3 module has been listed with the Bluetooth Special Interest Group (SIG) as a qualified an End Product. The Bluetooth SIG requires every product implementing Bluetooth technology to have a Declaration ID even though the end product references a Bluetooth design with its own Declaration ID. - Page 18 FCC Statement 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.
- Page 19 FCC Radiation Exposure Statement: This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. End users must follow the specific operating instructions for satisfying RF exposure compliance. Note 1: This module certified that complies with RF exposure requirement under mobile or fixed condition, this module is to be installed only in mobile or fixed applications.
