Guidance v06. According to RSS-102 Issue 5 March 2015 SAR evaluation is required if the separation distance between the user and/or bystander and the antenna and/or radiating element of the device is less than or equal to 20 cm, except when the device operates at or below the applicable output power level (adjusted for tune-up tolerance) for the specified separation distance defined in Table . Limits for SAR evaluation RF exposure evaluation is required if the separation distance between the user and/or bystander and the device’s radiating element is greater than 20 cm, except when the device operates as follows: • at or above 300 MHz and below 6 GHz and the source-based, time-averaged maximum e.i.r.p. of the device is equal to or less than 1.31 x 10-2 ƒ 0.6834 W (adjusted for tune-up tolerance), where ƒ is in MHz; The separation distance of the EUT should be less than 5mm.The measured maximum specified e.i.r.p of the EUT is 5.614dBm ≈ 3.64mW, which is far below the SAR exclusion threshold level 4mW, hence the EUT is excluded from SAR evaluation according to RSS-102 Issue 5 section 2.5.1. 2.3 X √2.441 / 5 = 0.72 <3
