It is a transmitter and has a built in battery;
Compliance with 47 CFR 15.247(i)
“Systems operating under the provisions of this section shall be operated in a manner
that ensures that the public is not exposed to radio frequency energy levels in excess of
the Commission's guidelines. See § 1.1307(b)(1) of this chapter.”
The EUT is a wrist-worn arm band operating in the 2.4 GHz band. It can be considered a
portable transmitter per 47 CFR 2.1093 because it can be used within 20cm of the user’s torso.
The antenna is internal to the unit and permanently attached. The antenna is a an inverted F
antenna with 0 dBi of gain. The maximum peak conducted output power is 0.687 mW.
The maximum peak radiated power is 0.687 mW eirp for FCC ID: Q3E-MB-R1G1. The
transmit frequency is 2401 to 2476MHz, therefore the EUT does not require routine SAR
evaluation because it falls below the low power threshold of 60/f(GHz)mW. Please see this
excerpt from KDB 447498 D01 Mobile Portable RF Exposure v04, item 2)(a)(i):
"a device may be used in portable exposure conditions with no restrictions on host
platforms when either the source-based time-averaged output power is <=60/f(GHz)mW
or all measured 1-g SAR are <0.4W.kg."
The applicant’s wireless radio, FCC ID: Q3E-MB-R1G1, is compliant with the requirements of
FCC 15.247(i).
