Box 1086 El Granada, CA 94018 tom@tncokenias.org Compliance Certification Services 16 June 2010 47173 Benicia Street Fremont CA 94538 Attention: Claire Hoque Re: Correction required on 3 class 2 permissive change grants Corrected attachments for upload Equipment: Radio modules Grantee, FCC ID, and Description Tropos Networks P9J-2411 2.4 GHz module Tropos Networks P9J-5805 5.8 GHz module Itron Electricity Meters SK9ITR900-1 902 MHz module Grant issue date: 10 June 2010 for all 3 grants Dear Claire, On reviewing the attachments on FCC website, the client noticed the following erros: a) I had the wrong antenna gain and power output for 2.4 GHz module, and b) The MPE calculations were in error and c) I submitted an earlier version of the user manual The attached MPE calculation is for 28.5 dBm into 7.4 dBi antenna, which is correct for 2.4 GHz. The calculated MPE is 56.4 cm. The attached user manual is the most current with 57 cm as MPE distance and is what they will provide with the product. Please arrange to have the same MPE calculation, the RFx document, and the user manual that accompany this letter, to be uploaded to all three applications and to correct the MPE distance listed on the grants. I apologize for the extra work and will take steps to prevent re-occurrence in the future. Time is of the essence so please arrange for the corrections as soon as possible and let me know when they are completed. If you have questions or need further information please don’t hesitate to call. Sincerely, T.N. Cokenias Agent for Tropos Networks and Itron Electricity Meters tel: 650-726-1263 fax: 650-726-1252 email tom@tncokenias.org
