App Note Title Application Note 5.2 European Union (EU) – CE The Lyra P modules are in conformity with the essential requirements and other relevant requirements of the Radio Equipment Directive (RED) (2014/53/EU). Please note that every application using the Lyra P module must perform the radio EMC tests on the end product, according to EN 301 489-17. It is ultimately the responsibility of the manufacturer to ensure the compliance of the end-product as a whole.
PAGE 7
App Note Title Application Note The Lyra S is a shielded design and comes with full modular approval. Separation   To meet the SAR exemption for portable conditions, the minimum separation distance indicated in Table 4 must be maintained between the human body and the radiator (antenna) at all times.

App Note Title Application Note 5.4 ISED Canada ISED This radio transmitter (IC: 3147A-LYRAS; HVIN: LYRA-S) has been approved by Innovation, Science and Economic Development Canada (ISED Canada, formerly Industry Canada) to operate with the embedded antenna and with the antenna type(s) listed in Table 3, with the maximum permissible gain indicated. Antenna types not included in this list, having a gain greater than the maximum gain listed, are strictly prohibited for use with this device.

App Note Title Application Note Final Note: As long as all the conditions above are met, further transmitter testing is not required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed (for example, digital device emissions, PC peripheral requirements, etc.). CAN ICES-003 (B) – Lyra S This Class B digital apparatus complies with Canadian ICES-003.

App Note Title Application Note Étiquetage des produits finis Les modules Lyra S ne sont pas étiquetés avec leur propre ID IC en raison de leur taille. Au lieu de cela, l'étiquette d'emballage contient l'ID IC. Dans tous les cas, lorsque l'ID IC n'est pas visible lorsque le module est intégré au sein d'un autre produit, cet autre produit dans lequel le module est installé devra porter une étiquette faisant apparaitre les référence du module intégré.
PAGE 11
App Note Title Application Note 5.5 Proximity to Human Body When using the Lyra S modules in an application where the radio is located close to the human body, the human RF exposure must be considered. FCC, ISED, and EU all have different standards and rules for evaluating the RF exposure.

App Note Title Application Note 5.6 Japan – MC The Lyra S are certified in Japan with certification number 209-J00457 The Lyra S modules are not labeled with their own ID due to their size. Instead, the packaging label contains the ID. In all cases when the ID is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module.

App Note Title Application Note 5.7 South Korea – KC The Lyra S modules have a RF certification for import and use in South-Korea. Certification number is: R-C-L7C-LYRAS When integrating the RF-certified module, an end-product is exempted from doing the RF emission testing, as long as the recommended design guidance is followed, and the approved antennas are used. EMC testing, and any other relevant test, might still be required for full compliance. 5.
