RF Exposure
The equipment under test (EUT) is a Hatch Baby Rest with BT 4.1 BLE function
operating in 2402-2480MHz. The EUT is powered by DC 5V/1A from adapter
with 120V/60Hz input. For more detail information pls. refer to the user manual.

Modulation Type: GFSK.
Bluetooth Version: BT 4.1 BLE(single mode)

Antenna Type: Integral antenna.
Antenna Gain: 1.6dBi.
The nominal conducted output power specified: -1.6dBm (+/-3dB).
The nominal radiated output power (e.i.r.p) specified: 0dBm (+/- 3dB).

According to the KDB 447498:
The maximun peak radiated emission for the EUT is 97.9dBμV/m at 3m in
the frequency 2402MHz
The EIRP = [(FS*D) ^2 / 30] mW = 2.7dBm
which is within the production variation.

The minimum peak radiated emission for the EUT is 97.5dBμV/m at 3m in
the frequency 2480MHz
The EIRP = [(FS*D) ^2 / 30] mW = 2.3dBm
which is within the production variation.

The maximun conducted output power specified is 1.4dBm = 1.4mW
The source- based time-averaging conducted output power
= 1.4 * Duty factor mW (where Duty Factor≤1)
= 1.4 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.
