Important Information United States
THIS PHONE MODEL HAS BEEN CERTIFIED IN
COMPLIANCE WITH THE GOVERNMENT'S
REQUIREMENTS FOR EXPOSURE TO RADIO
WAVES.
This mobile phone model SO-51C has been
designed to comply with applicable safety
requirements for exposure to radio waves.
Your wireless phone is a radio transmitter and
receiver. It is designed to not exceed the
limits* of exposure to radio frequency (RF)
energy set by governmental authorities.
These limits establish permitted levels of RF
energy for the general population. The
guidelines are based on standards that were
developed by international scientific
organizations through periodic and
thorough evaluation of scientific studies.
The standards include a safety margin
designed to assure the safety of all
individuals, regardless of age and health. The
radio wave exposure guidelines employ a
unit of measurement known as the Specific
Absorption Rate (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.
The highest SAR value as reported to the
authorities for this phone model when tested
for use by the ear is 0.82 W/kg*, when worn
on the body is 0.79 W/kg* and when WiFi
hotspot mode is 0.79 W/kg. For body-worn
operation, this phone has been tested and
meets the FCC RF exposure guidelines. Please
use an accessory designated for this product
or an accessory which contains no metal and
which positions the handset a minimum of
10 mm from the body.
For devices which include “WiFi hotspot”
functionality, SAR measurements for the
device operating in WiFi hotspot mode were
taken using a separation distance of 10 mm.
When using the device as a charger, you need
to put the phone on a flat surface and 20 cm
separation distance from user during the
charging mode.
Use of third-party accessories may result in
different SAR levels than those reported.
** Before a phone model is available for sale
to the public in the US, it must be tested and
certified by the Federal Communications
Commission (FCC) that it does not exceed the
limit established by the government-
