This modular must be installed and operated with a minimum distance of 20 cm between the radiator and user body.     If the FCC identification number 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. This exterior label can use wording such as the following: “Contains Transmitter Module FCC ID: 2ADBM-LS5BVD-N11S Or Contains FCC ID: 2ADBM-LS5BVD-N11S”When the module is installed inside another device, the user manual of the host must contain below warning statements;1. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:(1) This device may not cause harmful interference.(2) This device must accept any interference received, including interference that may cause undesired operation.2. Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.The devices must be installed and used in strict accordance with the manufacturer's instructions as described in the user documentation that comes with the product.Any company of the host device which install this modular with limit modular approval should perform the test of radiated emission and spurious emission according to FCC part 15C : 15.247 and 15.209 requirement, Only if the test result comply with FCC part 15C : 15.247 and 15.209 requirement,then the host can be sold legally.
