Statement:
Changes or modifications to this equipment not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
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, and (2) this device must accept any interference received, including interference that may cause undesired operation.
Notice for installation in host:
The final host/module combination may also need to be evaluated against the FCC Part15B criteria for unintentional radiators in order to be properly authorized for operation as a Part 15 digital device. The user’s manual or instruction manual for an intentional or unintentional radiator shall caution the user that changes or modifications not expressly approved by the party.
To ensure compliance with all non-transmitter functions the host manufacturer is responsible for ensuring compliance with the module(s) installed and fully operation. For example, if a host was previously authorized as an unintentional radiator under the Declaration of Conformity procedure without a transmitter certified module and a module is added, the host manufacturer is responsible for ensuring that the after the module is installed and operational the host continues to be compliant with the Part 15B unintentional radiator requirements.
Labelling:
The proposed FCC label format is to be placed on the module. If it is not visible when the module is installed into the system, “Contains FCC ID: 2BCT6-0002” shall be placed on the outside of final host system.
