RF Exposure NEEO Brain
The Neeo Brain is declared exempt for RF exposure considerations as per EN 62479: 2010
Where a transmitting device is intended to be used close to the human body device a SAR evaluation is required except in those cases where the device maximum output power is less than a maximum level specified in Annex A of EN 62479:2010 (Pmax)
EN 62479:2010 §4.2 *Low-power exclusion level (Pmax) states: ‘Low-power electronic and electrical equipment is deemed to comply with the provisions of this standard if it can be demonstrated that the available antenna power and/or the average total radiated power is less than or equal to the applicable low-power exclusion level Pmax.
Annex A contains example values for Pmax derived from existing exposure limits listed in the bibliography, such as the ICNIRP guidelines , IEEE Std C95.1-1999 , and IEEE Std C95.1-2005 .’
Council Recommendation 1999/519/EC Table 1 specifies the localised SAR limit for head and trunk as defined by ICNIRP for the General Public, therefore the ICNIRP specified Pmax limit for head and trunk in Table A.1 of EN 62479:2010 is applicable i.e. 20 mW.
Council Recommendation 1999/519/EC Table 1 specifies the localised SAR limit for limbs as defined by ICNIRP for the General Public, therefore the ICNIRP specified Pmax limit for limbs in Table A.1 of EN 62479:2010 is applicable i.e. 40 mW.
The maximum EIRP values of the Brain are below the specified Pmax thresholds of 20mW for head and trunk and 40mW for limbs.
*low-power exclusion level Pmax is defined in EN 62479:2010 §3.8 as: ‘specified condition on device output power, which may also depend on other variables such as frequency and distance of radiating source from persons, such that the exposure level produced by the source will not exceed a specific basic restriction. If the device output power is less than Pmax, then the device is deemed to comply with the basic restrictions’
