N7NOEM3 July 6, 1999 Federal Communications Commission Authorization and Standards Division 7435 Oakland Mills Rd. Columbia, M.D. 21046 RE: FCCID: N7NOEM3 Grantee: Sierra Wireless Inc. Equipment Class: Non-broadcast transmitter Application for Class II Permissive Change dated July 6, 1999 Dear Sir/Madam: The following information is submitted in support of a Class II Permissive Change to the certification of the N7NOEM3 transmitter. There are no physical or electrical changes as defined in Section 2.908. Presently, the N7NOEM3 transmitter has received a grant of equipment authorization for Emission Designators: 31K5FXW, 40K0F1D, 40K0F8W. We would like to request the addition of emission designator 40K0F3E to the present grant for the N7NOEM3 transmitter. Please advise me if we may provide any additional information for your review of this application for Class II Permissive change to the certification of the N7NOEM3 transmitter. Sincerely Markus Myers Engineering Technologist Sierra Wireless Inc. Proprietary and Confidential PAGE 3 July 13, 1999

N7NOEM3 Figure 2.1-3: Peak Deviation vs Time. Peak frequency deviation of a 1 kHz signal with audio input level increased by 20 dB (from reference level giving 8 kHz deviation) in one step. It should be noted that at approximately 7 sec. after applying a continuous audio signal, the DSP mute function reduces the modulation deviation by ~ 14%.
