RF Exposure
The Equipment under Test (EUT) is a Car unit for R/C VEHICLE model:
BY35013-24GT operating at 2.4GHz band. It is powered by 2 x 1.5V AA
batteries. 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: -1.0dBm (tolerance: +/- 3dB).
The normal conducted output power is -1.0dBm (tolerance: +/- 3dB).
Modulation Type: GFSK.

According to the KDB 447498:
The Maximum peak radiated emission for the EUT is 94.5dBµV/m at 3m in
the frequency 2440MHz
The EIRP = [(FS*D) ^2 / 30] mW = -0.73dBm
which is within the production variation.

The Minimum peak radiated emission for the EUT is 93.2dBµV/m at 3m in
the frequency 2402MHz
The EIRP = [(FS*D) ^2 / 30] mW = -2.03dBm
which is within the production variation.

The maximum conducted output power specified is 2.0dBm = 1.6mW
The source- based time-averaging conducted output power
= 1.6* Duty cycle mW <1.6 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
= 9.53 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 = 15.1014ms
Effective period of the cycle = 2.5507ms
DC = 2.5507ms / 15.1014ms = 0.1689 or 16.89%
