RF Exposure
The Equipment under Test (EUT) is a car unit for the R/C Vehicle/Car model:
BY35102-24GG operating at 2.4GHz band. It is powered by DC 9.6V (1 x 9.6V
rechargeable battery). For more detail information pls. refer to the user manual.

Antenna Type: Integral antenna.
Antenna Gain: 0dBi.
The normal radiated output power (e.i.r.p) is: -19.0dBm (tolerance: +/- 3dB).
The normal conducted output power is -19.0dBm (tolerance: +/- 3dB).
Modulation Type: GFSK.

According to the KDB 447498:
The Maximum peak radiated emission for the EUT is 76.0dBµV/m at 3m in
the frequency 2440MHz
The EIRP = [(FS*D) ^2 / 30] mW = -19.23dBm
which is within the production variation.

The Minimum peak radiated emission for the EUT is 74.9dBµV/m at 3m in
the frequency 2480MHz
The EIRP = [(FS*D) ^2 / 30] mW = -20.33dBm
which is within the production variation.

The maximum conducted output power specified is -16.0dBm = 0.025mW
The source- based time-averaging conducted output power
= 0.025* Duty cycle mW <0.1 mW(Duty cycle <100%)

The SAR Exclusion Threshold Level:
= 3.0 * (min. test separation distance, mm) / sqrt(freq. in GHz)
= 3.0 * 5 / sqrt (2.480) mW
= 9.5 mW

Since the source-based time-averaging conducted output power is well
below the SAR low threshold level, so the EUT is considered to comply
with SAR requirement without testing.

The duty cycle is simply the on-time divided by the period:
The duration of one cycle = 15.1449ms
Effective period of the cycle = 2.5362ms
DC = 2.5362ms / 15.1449ms = 0.1675 or 16.75%
