OEM INTEGRATION INSTRUCTIONS:

This device is intended only for OEM integrators under the following conditions:

The module must be installed in the host equipment such that 20 cm is maintained

between the antenna and users, and the transmitter module may not be co-located with

any other transmitter or antenna. The module shall be only used with the internal

antenna(s) that has been originally tested and certified with this module.

As long as 3 conditions above are met, further transmitter test will not be required.

However, the OEM integrator is still responsible for testing their end-product for any

additional compliance requirements required with this module installed (for example,

digital device emissions, PC peripheral requirements, etc.).

Validity of using the module certification:

In the event that these conditions cannot be met (for example certain laptop

configurations or co-location with another transmitter), then the FCC authorization for this

module in combination with the host equipment is no longer considered valid and the

FCC ID of the module cannot be used on the final product. In these circumstances, the

OEM integrator will be responsible for re-evaluating the end product (including the

transmitter) and obtaining a separate FCC authorization.

This device must be kept away from all persons by 20cm or more and installations using less

distance, or installations using antennas with gain greater than that with which this was

Certified will require additional approvals.
