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 U890 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 0.616 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). 13

is
a
low

•
This
handset
model
U890
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
0.616
W/kg
(10g)
•
The
SAR
limit
recommended
by
the
Institute
of
Electrical

Engineers
(IEEE),
which
is
1.6
W/kg
averaged
over
one
(1)
gramme
of
tissue
(for
example
USA,
Canada,
Australia
and
Taiwan).
