Recorded at least the six highest emissions. Emission frequency, amplitude, antenna
position, polarization and turntable position were recorded into a computer in which
correction factors were used to calculate the emission level and compare reading to the
applicable limit and only Q.P. reading is presented.
The test data of the worst-case condition(s) was recorded.
The bandwidth of test receiver is set at 200Hz for 9 KHz to 150 KHz measure, 10 KHz for
150 KHz to 30MHz measure and 120 KHz for 30 MHz to 1GHz measure.

Note:
8.2MHz Limit: (the bandwidth of the device in kHz)divided by (the center frequency of the
device in MHz)=121.9kHz/8.2MHz=14.87＜15,
So the limits 30m is (20log15 microvolts/meter)+40=63.5dBuV/m

6. Antenna Requirements

6.1. Limit

For intentional device, according to FCC 47 CFR Section 15.203, an intentional
radiator shall be designed to ensure that no antenna other than that furnished by the
responsible party shall be used with the device. And according to FCC 47 CFR
Section 15.209, if transmitting antennas of directional gain greater than 6dBi are used,
the power shall be reduced by the amount in dB that the directional gain of the
antenna exceeds 6dBi.

6.2. Result

The antennas used for this product are external Antenna with unique non standard
antenna port and that no antenna other than that furnished by the responsible
party shall be used with the device.
