Installation Guidance

The final host / module combination may also need to be evaluated against the FCC Part 15B 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 responsible for compliance

could void the user's authority to operate the equipment. In cases where the manual is provided only

in a form other than paper, such as on a computer disk or over the Internet, the information required

by this section may be included in the manual in that alternative form, provided the user can

reasonably be expected to have the capability to access information in that form.

To ensure compliance with all non-transmitter functions the host manufacturer is responsible for

ensuring compliance with the module(s) installed and fully operational. 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.

The FCC rule/s for this module are CFR 47 Part 15 Subpart C.

Additional testing and certification may be necessary when multiple modules are used.
