RF exposure analysis for the equipment with FCC ID: L2C0069TR

1. Introduction

The device with FCC ID: L2C0069TR is designed to be used in portable exposure conditions. It contains a 2.4GHz
radio which operates in Bluetooth 4.0 (2402-2480 MHz frequency band) and is intended for use within 20 cm of
humans.


2. SAR limits

According to § 2.1093 (d) (2) the limits for General Population/Uncontrolled exposure: 0.08 W/kg as averaged over the
whole-body and peak spatial-average SAR limit is 1.6 W/kg, averaged over any 1 gram of tissue over the whole body.


3. Compliance criteria:

Individual transmitters are deeded to comply with § 2.1093 requirements if the output power of the transmitter meets
the conditions specified in section 4.3.1 (Standalone SAR test exclusion) considerations of the document “KDB
447498 D01 Clause 4.3.1 General RF Exposure Guidance v06”.
