Device: 924 MHz (FM) Wireless Transmitter FCC ID: B4SAT14A Power Requirements: 1.2 VDC (1) NiMH Rechargeable Battery Applicable Rule Section: Part 15, Subpart C, Section 15.249 TEST RESULTS 15.249(a): The unit operates in the 902 to 928 MHz band at 924.19 and 924.89 MHz. The field strength of the fundamental did not exceed 50 milliV/M Average. The field strength of the harmonics did not exceed 500 microV/M Average. 15.249(b): Field strength readings were taken at three meters unless otherwise noted. 15.249(c): Emissions radiated outside band edges were greater than 50 dB below the specified the level of the fundamental or met the general radiated emission requirements of 15.209(a), whichever provided the lesser attenuation. 15.249(d): The peak field strength of any emission did not exceed the maximum permitted average field strength by more than 20dB under any condition of modulation. GENERAL NOTES 1. All measurements were made with a fully charged 1.2 VDC NiMH rechargeable battery installed in the unit. 2. All user accessible controls were adjusted to produce maximum emissions. 3. The device was tested with the following external accessories: I Pod NANO 4. The unit operates at the following frequencies: 924.19 and 924.89 MHz The unit was tested at the following frequency: 924.19 MHz 5. The frequency range was scanned from 30 MHz to 10 GHz. All emissions not reported were more than 20 dB below the specified limit.
