FCC ID: AK8M20DAL1
To whom it may concern,We, UL Japan, Inc, hereby declare that Wireless communication module, model: AW-XM501 (FCC ID:AK8M20DAL1) of Sony Interactive Entertainment Inc. is exempt from RF exposure SAR evaluation because
the available maximum time-averaged power or effective radiated power (ERP), whichever is greater, is lessthan or equal to the threshold Pth (mW) described in the following formula according to the Code of FederalRegulation title 47 section 1.1307(b)(3)(i)(B). This method is used at separation distances d (cm) from 0.5
centimeters to 40 centimeters and at frequencies from 0.3 GHz to 6 GHz (inclusive) for single RF sources. Pth isgiven by:𝑃mW𝐸𝑅𝑃
