Analysis Report The Equipment Under Test (EUT), is a portable 2.4GHz Transceiver (Piano Unit) for a RC Piano. The sample supplied operated on 1 channel, normally at 2470MHz. The EUT is powered by 3 x 1.5V AA batteries. After switching on the EUT, the piano will emit sounds based on the keyboard button pressed. Antenna Type: Internal, Integral antenna Antenna Gain: 0dBi Nominal rated field strength is 95.5dBμV/m at 3m (Peak), 84.7dBμV/m at 3m (Average) Maximum allowed production tolerance: +/- 3dB According to the KDB 447498: Based on the maximum average field strength of production tolerance was 87.7dBμV/m at 3m in frequency 2.470GHz. Thus, it below calculated field strength according to minimum SAR exclusion threshold level as follows: The worst case of SAR Exclusion Threshold Level: = 3.0 * (min. test separation distance, mm) / sqrt(freq. in GHz) = 3.0 * 5 / sqrt (2.483.5) mW = 9.52 mW According to the KDB 412172 D01: EIRP = [(FS*D) ^2*1000 / 30] Calculated Field Strength for 9.52mW is 105dBuV/m @3m Since maximum average field strength plus production tolerance < = 105dBuV/m @3m and antenna gain is > = 0.0dBi, it is concluded that maximum Conducted Power and Field Strength are well below the SAR Exclusion threshold level, so the EUT is considered to comply with SAR requirement without testing.

The EUT uses a permanently attached antenna which, in accordance to section 15.203, is considered sufficient to comply with the pervisions of this section. 2. Pursuant to FCC part 15 Section 15.215(c), the 20 dB bandwidth of the emission was contained within the frequency band designated (mentioned as above) which the EUT operated. The effects, if any, from frequency sweeping, frequency hopping, other modulation techniques and frequency stability over excepted variations in temperature and supply voltage were considered.
