persons. In this context, the term ”fixed location” means that the device is physically secured at one location

and is not able to be easily moved to another location.

OEM Integration Instructions

This device is intended only for OEM integrators under the following conditions� The module can be used to

installation in another host. The antenna must be installed such that 20 cm is maintained between the antenna

and users, and the transmitter module may not be co-located with any other transmit or antenna. The module

shall be only used with the integral 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 requirement with this module installed

(for example, digital device emission, PC peripheral requirements, etc.)

Notice:

In the event that these conditions cannot be met (for example certain laptop configuration 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 and circumstance, the OEM integrator will

be responsible for re-evaluating. The end product (including the transmitter) and obtaining a separate FCC authorization.

The final end product must be labeled in a visible area with the following:

”Contains Transmitter Module FCC ID:

2AC7Z­ESPWROOMDA”

or

”Contains FCC ID: 2AC7Z­ESPWROOMDA”
