RF Exposure
The equipment under test (EUT) is a R/C Boat operating at 2.4G Band. The
EUT can be powered by DC6.0V (4 x 1.5V AAA batteries). For more
detail information pls. refer to the user manual.

Antenna Type: Integral antenna.
Antenna Gain: 2dBi.
The normal radiated output power (e.i.r.p) is: 2.0dBm (tolerance: +/- 3dB).
The normal conducted output power is 0.0dBm (tolerance: +/- 3dB).
Modulation Type: GFSK.

According to the KDB 447498:
The Maximum peak radiated emission for the EUT is 96.0dBµV/m at 3m in
the frequency 2406MHz
The EIRP = [(FS*D) ^2 / 30] mW = 0.77dBm
which is within the production variation.

The Minimum peak radiated emission for the EUT is 95.1dBµV/m at 3m in
the frequency 2410MHz
The EIRP = [(FS*D) ^2 / 30] mW = -0.13dBm
which is within the production variation.

The maximum conducted output power specified is 3dBm = 2.0mW
The source- based time-averaging conducted output power
= 2.0* Duty cycle mW <2.0 mW(Duty cycle <100%)

The SAR Exclusion Threshold Level:
= 3.0 * (min. test separation distance, mm) / sqrt(freq. in GHz)
= 3.0 * 5 / sqrt (2.414) mW
= 9.65 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 = 20.4348ms
Effective period of the cycle = 1.4493ms
DC =1.4493ms / 20.4348ms =0.0709 or 7.09%
