BT852 Datasheet If the condition above is 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. IMPORTANT NOTE If this condition cannot be met (for example, certain laptop configurations or co-location with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID cannot be used on the final product.
BT852 Datasheet This device is intended only for OEM integrators under the following conditions: 1. The transmitter module may not be co-located with any other transmitter or antenna. If the condition above is 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. Cet appareil est conçu uniquement pour les intégrateurs OEM dans les conditions suivantes: 1.
BT852 Datasheet Le présent émetteur radio (IC: 3147A-BT852 a été approuvé par Industrie Canada pour fonctionner avec les types d'antenne énumérés cidessous et ayant un gain admissible maximal. Les types d'antenne non inclus dans cette liste, et dont le gain est supérieur au gain maximal indiqué, sont strictement interdits pour l'exploitation de l'émetteur. EUROPEAN UNION REGULATORY The BT85x has been tested for compliance with relevant standards for the EU market. BT852 was tested with a 0.
BT852 Datasheet Signature of Authorized Person: BLUETOOTH SIG APPROVALS 13.1. Application Note: Subsystem Combinations This application note covers the procedure for generating a new Declaration ID for a Subsystem combination on the Bluetooth SIG website. In the instance of subsystems, a member can combine two or more subsystems to create a complete Bluetooth End Product solution.
BT852 Datasheet shows the basic subsystem combination of a controller and host subsystem. The Controller provides the RF/BB/LM and HCI layers, with the Host providing L2CAP, SDP, GAP, RFCOMM/SPP and any other specific protocols and profiles existing in the Host subsystem listing. The design may also include a Profile Subsystem.
