17 November 2005 Mike Cyr Daniels Electronic Ltd. 43 Erie Street, Victoria, British Columbia Canada V8V 1P8 Dear Mr. Cyr, Enclosed is the 47 CFR Part 2 Subpart J Section 2.1053 (Radiated Spurious Emissions) Test Report for three UHF Transmitters (i.e., Models UT-4E400, UT-4E450, and UT-4E500), and the CD-ROM containing this Test Report in PDF Format. Please check it thoroughly for discrepancies and please contact us immediately if you have any questions or if you identify any problems. This is an official copy of your Test Report, complete with the original Acme Testing Co. staff signatures. You should retain this Test Report as the official record of testing, as proof of compliance in the future. Please be aware that our internal controls require us to retain a historical copy of your Test Report on file for a three-year period, after which our copy of your Test Report will be destroyed. Please note that the FCC Certification Procedure Rules require that this Test Report (and all other Exhibits that form the FCC Filing Package on your UHF Transmitters) must be retained by the Responsible Party for two years after the manufacturing of the product has been permanently discontinued [cf., 47 CFR Part 2 Section 2.938(c)]. Please note that Acme Testing Co. is accredited by the American Association for Laboratory Accreditation (A2LA). Further, Acme Testing Co.’s Open Area Test Site [OATS] # 1 is registered with the FCC. Thank you for your business! We look forward to being of service to you in the future. Yours sincerely, :sg Enclosure Acme Testing Co. 2002 Valley Highway, P.O.
