RF Exposure Information of This Product (for Japan)
This mobile phone A201SO is compliant with the Japanese technical regulations
exposure to radio frequency (RF) electromagnetic energy.
This mobile phone is designed to comply with the Japanese technical regulations on human
exposure to RF electromagnetic energy. The regulations establish the permissive limits of the
energy, that are consistent with the restrictions set by ICNIRP
World Health Organization (WHO) and ICES
designed to assure the safety of all persons regardless of age and health.
The permissive limits are defined as SAR (Specific Absorption Rate) for the frequencies under 6
GHz and PD (Power Density) for the frequencies over 6 GHz in the regulation. For mobile phones,
the stipulated permissive levels are: SAR 2.0 W/kg, PD: 2 mW/cm
the indication of Combined Radiation Ratio (CRR), which summarizes the compliance with the
limits, on condition that mobile phone supports simultaneous transmission of the frequency bands
that should be evaluated by each corresponding limit. Mobile phones which CRR is less or equal
than 1 qualifies the permissive limits.
The CRR values for this mobile phone are: 0.8425
*5
when worn on the body. The actual SAR and PD of mobile phones while operating can be well
below that indicated above. This is due to automatic changes to the power level of the device to
ensure it only uses the minimum required to access the mobile network(s). There may be slight
differences in SAR and PD levels for each product, but they all satisfy the permissive limits.
This mobile phone can be used at positions other than at the ear. By using accessories such as a
belt clip holster that maintains a 1.5 cm separation with no metal (parts) between it and the body,
this mobile phone is certified the compliance with the Japanese technical regulations.
