Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: R1DG120904005-00 FCC §1.1307(b) & §2.1093 - RF EXPOSURE Applicable Standard According to FCC §2.1093 and §1.1307(b) (1), systems operating under the provisions of this section shall be operated in a manner that ensure that the public is not exposed to radio frequency energy level in excess of the Commission’s guideline. According to FCC KDB 447498 D01 Mobile Portable RF Exposure v04 section 5, Push-to-talk (PTT) devices: a) RF exposure is evaluated with a duty factor of 50% when the actual operating duty factor is ≤ 50%. Devices supporting higher duty factors shall be evaluated at the maximum duty factor; for example, devices supporting operator-assisted PSTN calls. Contact the FCC Laboratory when unable to test a device at the required duty factor due to hardware limitations or other reasons. b) Portable PTT devices i) The power thresholds and operating conditions in Table 1 are used to determine SAR test requirements for PTT radios required to comply with the general population exposure limit. When the occupational exposure limit applies, these power thresholds are increased by a factor of five (5) to determine the test requirements. SAR is required for PTT devices with maximum output power greater than these thresholds.28 SAR evaluation is also required for separation distances smaller than those in Table 1. Contact the FCC Laboratory to determine if SAR evaluation is necessary for other frequencies or when the SAR is very low. SAR Evaluation Power Thresholds for PTT devices,f≤0.5GHz Exposure Conditions mW (for uncontrolled) mW (for occupational) Held to face ≥2.5cm 250 1250 Body-worn ≥1.5cm 200 1000 Body-worn ≥1.0cm 150 750 ii) Additional SAR evaluation with a SAM phantom is required for PTT devices with held-to-ear operating mode.29 Contact the FCC Laboratory for device operating and test configurations. Routine SAR evaluation refers to that specifically required by §2.1093, using measurements or computer simulation. When routine SAR evaluation is not required, portable transmitters with output power greater than the applicable low threshold require SAR evaluation to qualify for TCB approval.
