Radio frequency energy
Your handset is a low-power radio transmitter
and receiver. When it is turned on, it receives
and transmits radio frequency (RF) energy (radio
waves). The system that handles the call (the
network) controls the power level at which the
handset transmits.
Further detailed information is given in this
manual. 
Exposure to radio frequency
energy 
Radio wave exposure and Specific
Absorption Rate (SAR) information 
This handset model U900 has been designed
to comply with safety, requirements for
exposure to radio waves. This requirement is
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 a standardised method 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 LG phone models, they
are all designed to meet the relevant
guidelines for exposure to radio waves
The SAR limit recommended by the
International Commission on Non ionising
Radiation Protection (ICNIRP), is 2W/kg
averaged over ten (10) gramme of tissue
The highest SAR value for this model phone
tested by DASY4 for use at the ear is 1.38
W/kg (10g)
The SAR limit recommended by the Institute
of Electrical and Electronics Engineers (IEEE),
which is 1.6 W/kg averaged over one (1)
gramme of tissue (for example USA, Canada,
Australia and Taiwan).
