1.0 Introduction

Dialog Semiconductor B.V. has obtained a Modular

Approval Certificate (US, EU) for CVMDECT. When

meeting the conditions as referenced in this document,

this implies that those tests already covered by the

Modular Approval Certificate don’t need to be rerun on

the end-product level. This may alleviate the overall

regulatory approval process of the end-product.

tem level certification process though. Any regulatory standards not covered by the available Modular Approval certificates will still need to be tested on end-product/system level. 2.1 DESCRIPTION When a wireless module has passed the Modular Approval process, and when the host conforms to certain conditions (this will be detailed in the subsequent sections), then the end-product containing this module will not need to be tested against the regulatory standards covered by the module’s certificates. 2.

2.4.5 Le présent émetteur radio (identifier le dispositif par son numéro de certification ou son numéro de modèle s'il fait partie du matériel de catégorie I) a été approuvé par Industrie Canada pour fonctionner avec les types d'antenne énumérés ci-dessous et ayant un gain admissible maximal et l'impédance requise pour chaque type d'antenne. Les types d'antenne non inclus dans cette liste, ou dont le gain est supérieur au gain maximal indiqué, sont strictement interdits pour l'exploitation de l'émetteur.

2.4.6 2.5 MISCELLANEOUS COMMENTS In FCC terminology, a “Host” is what is referred to in DECT as a “fixed part”. The FCC term “Mobile” corresponds with the DECT term “portable part”, provided that the device is >20cm from the human body. A DECT termed “portable part” <20cm from the human body is referred to as “Portable” in FCC terminology. Safety Requirements This section provides of an overview of the safety requirements you must adhere to when working with CVMDECT.

3.1.1 FCC-04-165 now allows different antennas may be certified with one module. Dialog Semiconductor B.V. has obtained Modular Approval for CVMDECT using a specific external printed antenna. FCC-04-165 dictates that the certification measurements must to be performed with the highest gain antenna and any other antenna must have a similar radiation pattern.
PAGE 6
3.3 OTHER ANTENNAS If an antenna is connected to CVMDECT that has a dissimilar radation pattern than that of the SC14CVMDECT_AF01_SF01 design and/or if the antenna has a higher gain than that of the SC14CVMDECT_AF01_SF01 design, then FCC-04-165 dictates that the Modular Approval is invalidated and that recertification is required on end-product/system level. In that case, the host PCB design must adhere to the same PCB layer stackup (material, layer spacings) as mentioned in section 3.1.1.
