Its accecting range is frequency deviation plus-minus 10ppm or less,under -10 degree to +60 degree temperature by using Tokyo Denpa made crystal oscillator. (2)How to reduce the spurious radiation In order to suppress the radiation,LC filter is positioned after current amplification part. It is low passed filter which forms pie shape with third layered. (3)Restriction of Audio modulation In order to restrict audio modulation,diode limiter circuit(ZD101,ZD102) is put into pre-emphasis circuit. 4.Operating Menu 42 -01␣ Push mode key for 1s 638.125 2s later Channel Select Frequency Up or Down 42-15␣ Change the CH 1.4s laterUp or DownMode key Group Select a hyphen brinks Change the Group a hyphen glows 02:15␣␣ Estimated Time [Channel Select mode] Select the channel by Up or Down key.

Applicable Standards TIA 603, FCC CFR 47 Parts 2 and 74 Applicant: AZDEN CORPORATION FCC ID: BZB2000BT Report: A\AZDEN_BZB\1492AT11\1492AT11TestReport.doc Page 6 of 16 TEST PROCEDURES Power Line Conducted Interference: The procedure used was TIA 603 using a 50uH LISN. Both lines were observed with the UUT transmitting. The bandwidth of the spectrum analyzer was 10 kHz with an appropriate sweep speed. Bandwidth 20 dB: The measurements were made with the spectrum analyzer's resolution bandwidth (RBW) = 1 MHz and the video bandwidth (VBW) = 3 MHz and the span set as shown on plot. Power Output: For a device with a fixed antenna, RF power is measured as ERP as the antenna is permanently attached. The substitution method was used as described in TIA-603- C. Antenna Conducted Emissions: The RBW = 100 kHz, VBW = 300 kHz and the span set to 10.0 MHz and the spectrum was scanned from 30 MHz to the 10 th Harmonic of the fundamental. Above 1 GHz the resolution bandwidth was 1 MHz and the VBW = 3 MHz and the span to 50 MHz. Radiation Interference: The test procedure used was TIA 603 using an Agilent spectrum receiver with pre-selector. The bandwidth (RBW) of the spectrum TIA 603 receiver was 100 kHz up to 1 GHz and 1 MHz above 1 GHz with an appropriate sweep speed. The VBW above 1 GHz was 3 MHz. The analyzer was calibrated in dB above a microvolt at the output of the antenna.
