Analysis Report
Report No.: 15040305HKG-003

The Equipment Under Test (EUT) is a 2.4GHz Transceiver (Helicopter Unit) for a RC
helicopter operating at 2411MHz ~ 2465MHz. The EUT is powered by 1 X 3.7V
rechargeable battery (Li-Poly). After switch on the EUT and paired with controller, the EUT
can be controlled to fly forward, backward and turning left/right direction by the
corresponding controller. Using an USB charging cable can charge the internal battery in
the helicopter via PC.

Antenna Type: Internal integral antenna
Antenna Gain: 0dBi
Nominal rated field strength: 93.6dBµV/m at 3m
Maximum allowed field strength of production tolerance: +3dB / - 3dB

According to the KDB 447498:

Based on the Maximum allowed field strength of production tolerance was 96.6dBµV/m
at 3m in frequency 2.4GHz, thus;

The EIRP = [(FS*D) ^2*1000 / 30] = 1.371mW

Conducted power = Radiated Power (EIRP) – Antenna Gain
So;

Conducted Power = 1.371mW

The SAR Exclusion Threshold Level:
= 3.0 * (min. test separation distance, mm) / sqrt(freq. in GHz)
= 3.0 * 5 / sqrt (2.465) mW
= 9.55 mW

Since the above conducted output power is well below the SAR Exclusion threshold level,
so the EUT is considered to comply with SAR requirement without testing.
