FCC ID: CINM-809 DATE: MARCH 15, 2000 REPORT #: T:\CUS\C\CHIAYO\CHI66T0\CHI66T0.RPT PAGE: 1 2.1033(C)(14) The data required by 2.1046 through 2.1057 is submitted below. 2.1046 RF_power_output. ERP was measured by the method described later in this report. The input power to the final stage was measured with a 9.0V supply connected in place of the 1.5V battery. INPUT POWER: FOR 9.0 V OPERATION (8.9V)(0.0026A) = 23.14MilliWatts OUTPUT POWER: FOR 9.0 V OPERATION 1.0 mWATTS ERP R.F.

Measure frequency responce over the frequency range from 100Hz to 20,000Hz. The audio frequency response curve is shown in EXHIBIT # 9. (b) Modulation Limiting - See Exhibits # 10A-10C. 2.1049 (c) Occupied_bandwidth: Using TIA/EIA 2.2.10 Accoustic Microphone Sensitivity test procedure to determine if the UUT could be put into modulation limiting and limiting could not be reached, the maximum deviation was only +40KHz. Using this test procedure the frequency of maximum sensitivity was determined to be 500Hz. a.
