The maximum peak spatial – 1g average SAR measured was found to 0.705W/Ks for head configuration and 0.241W/Kg for body configuration with 50% usage-based time-averaging applied for PTT device. The limit for SAR 1 gram average peak spatial average is 8.0W/Kg for Occupational/Controlled.

For body configuration tests, all the supplied additional body-worn accessories were checked through pre-scans and confirmed that those options were not affecting SAR compliance. Therefore, the final evaluation for body configuration was performed only with M/N: MB-103 Belt Clip, M/N HM-167 Speaker Microphone, and M/N: BP-245H Li-ion rechargeable battery packs.
