Sony Ericsson T238 User Manual

English
Radio wave exposure and Specific Absorption 
Rate (SAR) information

Addendum to User’s Guide
This mobile phone model T230/T238 has been designed to comply 
with applicable safety requirements for exposure to radio waves. 
These requirements are based on scientific guidelines that include 
safety margins designed to assure the safety of all persons, 
regardless of age and health.

The radio wave exposure guidelines employ a unit of 

measurement known as the Specific Absorption Rate, or SAR. 
Tests for SAR are conducted using standardized methods with 
the phone transmitting at its highest certified power level in all 
used frequency bands.

While there may be differences between the SAR levels of 

various phone models, they are all designed to meet the relevant 
guidelines for exposure to radio waves.

For more information on SAR, please refer to the safety 

chapter in the User’s Guide.

SAR data information for residents in countries that have 

adopted the SAR limit recommended by the International 
Commission on Non-Ionizing Radiation Protection (ICNIRP), 
which is 2 W/kg averaged over ten (10) grams of tissue (for 
example European Union, Japan, Brazil and New Zealand):

The highest SAR value for this model phone when tested 

by Sony Ericsson for use at the ear is 0.74 W/kg (10g). 

SAR data information for residents in countries/regions that 

have adopted the SAR limit recommended by the Institute of 
Electrical and Electronics Engineers (IEEE), which is 1.6 W/kg 
averaged over one (1) gram of tissue (for example USA, Canada, 
Australia and Taiwan):

The highest SAR value for this model phone when tested by 

Sony Ericsson  for use at the ear is 1.23 W/kg (1g).
