January 08, 2009 TIMCO Engineering Subject: Response letter to Job 11UC9 / 12IC9 - The Nielsen Company The purpose of this letter is to respond to questions you had related to the above applications. The device subject to equipment authorization contains a module already approved under FCC ID:OUR9XSTREAM. The applicant has made no modifications to the approved module. The antenna used by the applicant is an approved antenna listed in the user manual for the module. This application includes (3) different models. Each model contains electrically identical transceivers. We preformed exploratory testing on all (3) models and reported the worst-case data. The conducted emissions data was collected using the Checkout model, as it is the only model that connects to the AC. All other data was collected using the small black shopping cart model. I submitted a revised 731 form listing the approved module. The approved module at (900) MHz lists has a power density of (0.547) mW/cm^2 and a corresponding power density ratio of (0.9116). The EUT operating at (2.4) GHz has a power density of (0.00054) mW/cm^2 and a corresponding power density ratio of (0.00054). The summed power density ratio of the (2) transmitters operating simultaneously is (0.91214) which is below the limit of (1). Should you have any questions or concerns, please feel free to contact me directly. Regards, Steven Hoke EMC Site Manager WHR001 Job 11UC9 letter (third reply).doc 1 of 1
