RF Exposure Info

Analysis Report Report No.: 14050712HKG-001 The equipment under test (EUT) is a transmitter for Remote door bell operating at 315MHz which is operated by a crystal. The EUT is powered by 4 x AAA new battery. There are a test button and a microphone inside the EUT. The transmitter will be activated and then transmit a signal to corresponding door bell receiver once either the microphone can be received the chime sound from other door bell or the test button is pressed by the user. For microphone portion, the transmitter will cease transmission within 5 seconds after activation. For test button, the manually operated transmitter will automatically deactivate the transmitter within not more than 5 seconds of being released. Antenna Type: Internal integral antenna Antenna Gain: 0dBi Nominal rated field strength: 85.4 dBμV/m at 3m Maximum allowed field strength of production tolerance: +/- 3dB According to the KDB 447498: Based on the Maximum allowed field strength of production tolerance was 88.4 dBμV/m at 3m in frequency 2.4GHz, thus; The EIRP = [(FS*D) ^2*1000 / 30] = 0.104mW Conducted power = Radiated Power (EIRP) – Antenna Gain So; Conducted Power = 0.104mW. The SAR Exclusion Threshold Level: = 3.0 * (min. test separation distance, mm) / sqrt(freq. in GHz) = 3.0 * 5 / sqrt (0.315) mW = 26.73 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.

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.
