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.).

IMPORTANT NOTE: In the event that these conditions cannot be met (for example certain

laptop configurations or co-location with another transmitter), then the IC authorization is no

longer considered valid and the IC No. 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 IC authorization.

End Product Labeling

This transmitter module is authorized only for use in device where the antenna may be

installed such that 20 cm may be maintained between the antenna and users. The final end

product must be labeled in a visible area with the following: “Contains transmitter module IC:

IC: 4491A-WN4521L”.

Contient le module d'émission IC: IC: 4491A-WN4521L

IMPORTANT NOTE for OEM integrator:

This module is intended for OEM integrator.

The OEM integrator is still responsible for
