Although device is a desktop unit that is in mobile exposure category (d>20cm), the
following calculation uses portable exposure low threshold limit for a more conservative
estimate.

Based on the test report,

Maximum peak conducted 11.42dBm = 13.868mW
output power
Maximum antenna gain 2.81dBi
EIRP 26.485mW

The SoundLink™ wireless music system is classified as a Bluetooth® data “sink” with a
duty cycle that does not exceed 5% in normal operation. For the purposes of worst case
estimation a duty-cycle of 10% is considered.

Therefore,
Source based time averaged Conducted Output Power = 1.3868mW
Source based time averaged EIRP = 2.6485mW

Low threshold for SAR exemption 60/f(GHz) = 60/2.441 = 24.6mW

Since both conducted output power and EIRP (source based time averaged) are below
the low threshold for SAR exemption. Device complies with FCC RF radiation exposure
limits for general population as a portable device.
