D. Because the metal case is shielding the RF signal, it is recommended not to install it in the metal case E. With regard to the use environment, wireless signals are easily affected by the surrounding environment, such as trees, metals and other obstacles will have a certain absorption of wireless signals, so in practical applications, the distance of data transmission is affected to a certain extent 10 Recommended reflux temperature Key features of the profile： - Initial Ramp=1-2.
Integrator is reminded to assure that these installation instructions will not be made available to the end-user of the final host device. The final host device, into which this RF Module is integrated" has to be labeled with an auxiliary label stating the FCC ID of the RF Module, such as "Contains FCC ID: OMCBTAUD2 "This device complies with part 15 of the FCC rules.
Déclaration d'exposition aux radiofréquences pour IC L'appareil a été évalué pour répondre aux exigences générales en matière d'exposition aux RF. L'appareil peut être utilisé dans des conditions d'exposition mobiles. La distance de séparation minimale est de 20 cm. Module statement The single-modular transmitter is a self-contained, physically delineated, component for which compliance can be demonstrated independent of the host operating conditions, and which complies with all eight requirements of § 15.
Integration instructions for host product manufacturers according to KDB 996369 D03 OEM Manual v01 2.2 List of applicable FCC rules FCC Part 15.247 2.3 Specific operational use conditions This transmitter/module and its antenna(s) must not be co-located or operating in conjunction with any transmitter. This information also extends to the host manufacturer’s instruction manual. 2.4 Limited module procedures Not applicable 2.
