RF Exposure
The equipment under test (EUT) is a Toy RC Wrist Racer COMPOSITE
operating at 2.4G Band. The EUT can be powered by DC4.5V (3 x 1.5V AAA
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 92.8dBµV/m at 3m in
the frequency 2405MHz
The EIRP = [(FS*D) ^2 / 30] mW = -2.43dBm
which is within the production variation.

The Minimum peak radiated emission for the EUT is 91.7dBµV/m at 3m in
the frequency 2440MHz
The EIRP = [(FS*D) ^2 / 30] mW = -3.53dBm
which is within the production variation.

The maximum conducted output power specified is 1dBm =1.26mW
The source- based time-averaging conducted output power
=1.26* Duty cycle mW <1.26 mW(Duty cycle <100%)

The SAR Exclusion Threshold Level:
= 3.0 * (min. test separation distance, mm) / sqrt(freq. in GHz)
= 3.0 * 5 / sqrt (2.475) 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 = 20.4058ms
Effective period of the cycle = 173.9µs x 4 = 695.6µs=0.6956ms
DC =0.6956ms / 20.4058ms =0.0341 or 3.41%
