RF Exposure
The equipment under test (EUT) is a Bluetooth speaker with BT 5.0 BR+EDR
function operating in 2402-2480MHz. The EUT is only powered by DC 20V by
rechargeable battery. For more detail information pls. refer to the user manual.

Modulation Type: GFSK, π/4-DQPSK
Bluetooth Version: 5.0 (Single Mode BR+EDR)

Antenna Type: Integral antenna.
Antenna Gain: -0.68dBi.
The nominal conducted output power specified: 1dBm (+/-2dB).
The nominal radiated output power (e.i.r.p) specified: 0.32dBm (+/-2dB).

According to the KDB 447498:
The maximun peak radiated emission for the EUT is 97.15dBμV/m at 3m
in the frequency 2441MHz
The EIRP = [(FS*D) ^2 / 30] mW = 1.92dBm
which is within the production variation.

The minimum peak radiated emission for the EUT is 94.16dBμV/m at 3m
in the frequency 2402MHz
The EIRP = [(FS*D) ^2 / 30] mW = -1.07dBm
which is within the production variation.

The maximun conducted output power specified is 3dBm = 2.0mW
The source- based time-averaging conducted output power
= 2.0 * Duty factor mW (where Duty Factor≤1)
= 2.0 mW

The SAR Exclusion Threshold Level:
= 3.0 * (min. test separation distance, mm) / sqrt(freq. in GHz)
= 3.0 * 5 / sqrt (2.480) 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.
