Owlet Smart Sock System (OSS) and its key differentiating features.

^a Industry standard measurement for radio wave absorption is known as specific absorption rate (SAR) and is measured in watts per kilogram of flesh (W/kg). The maximum safe SAR level set by the Federal Communications Commission (FCC) for transmitters on a human appendage is 4.0 W/kg. The OSS level is 0.0005 W/kg, which is 8000 times below the maximum safe threshold and more than 2000 times less than that of common cellular phones.

^b Base station sounds an 80-decibel alarm [dB(A)/10 cm], which is in accordance with Food and Drug Administration standards that requires no less than 75 dB(A) for in-home monitors and no less than 70 dB(A) for hospital monitors.
