R IC O H C O M P A N Y , L T D declares that M odel : O ption(s) for R adiocom m unications
com plies w ith F C C radiation exposure requirem ent specified in the FC C R ules 2.1093.
T he “R -W L 54M N “ has 115.35 m W of conducted Peak O utput pow er and 230.14 m W of E IR P .
T his equipm ent is considered as a m obile device so that S A R testing is excluded.
so that S A R testing is excluded. T he F ollow ing calculation is the reference data for 20cm distance.

R F E xp osu re C alcu lations:

T he follow ing inform ation provides the m inim um separation distance for the highest gain
antenna provided w ith the “R -W L 54M N “ as calculated
from FC C O E T B ulletin 65 A ppendix A , T able (B ) L im its for G eneral P opulation / U ncontrolled
E xposure. T his calculation is based on the highest E IR P possible fro m the system ,
considering m axim um pow er and antenna gain, and considering a 1.0m W /cm ^2 uncontrolled
exposure lim it. T he F riis form ula used w as:

S = (P * G ) / (4* π * r 2 )
