RF Exposure
The Equipment under Test (EUT) is a Control unit for DRONE DX 5INCH
STUNT model: DX-2 operating at 2.4GHz band. It is powered by DC 9.0V (6 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: -2.0dBm (tolerance: +/- 3dB).
The normal conducted output power is: -2.0dBm (tolerance: +/- 3dB).
Modulation Type: GFSK.

According to the KDB 447498:
The Maximum peak radiated emission for the EUT is 93.8dBµV/m at 3m in
the frequency 2410MHz
The EIRP = [(FS*D) ^2 / 30] mW = -1.43dBm
which is within the production variation.

The Minimum peak radiated emission for the EUT is 93.4dBµV/m at 3m in
the frequency 2442MHz
The EIRP = [(FS*D) ^2 / 30] mW = -1.83dBm
which is within the production variation.

The maximum conducted output power specified is 1dBm = 1.3mW
The source- based time-averaging conducted output power
= 1.3* Duty Cycle mW < 1.3mW (Duty Cycle<100%)

The SAR Exclusion Threshold Level:
= 3.0 * (min. test separation distance, mm) / sqrt(freq. in GHz)
= 3.0 * 5 / sqrt (2.475) mW
= 9.53mW
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 duration of one cycle = 6.300ms
Effective period of the cycle = 0.460ms
DC = 0.46ms/6.300ms = 0.073 or 7.3%
