Guidelines for safe and e cient use
Please read these simple
guidelines. Not following
these guidelines may be
dangerous or illegal.
Exposure to radio
frequency energy
THIS DEVICE MEETS
INTERNATIONAL GUIDELINES
FOR EXPOSURE TO RADIO
WAVES
Your mobile device is a radio
transmitter and receiver. It is
designed and manufactured
not to exceed the limits for
exposure to radio frequency
(RF) recommended by
international guidelines
(ICNIRP). These limits are part
of comprehensive guidelines
and establish permitted
levels of RF energy for the
general population. The
guidelines were developed
by independent scientific
6LG GT400 | User Guide
organisations through
periodic and thorough
evaluation of scientific
studies. The guidelines
include a substantial safety
margin designed to assure
the safety of all persons,
regardless of age and health.
The exposure standard for
mobile devices employs a
unit of measurement known
as the Specific Absorption
Rate, or SAR. The SAR limit
stated in the international
guidelines is 2.0 W/kg*. Tests
for SAR are conducted using
standard operating positions
with the device transmitting
at its highest certified power
level in all tested frequency
bands. Although the SAR is
determined at the highest
certified power level, the
actual SAR of the device
while operating can be well
below the maximum value.
This is because the device
is designed to operate at
multiple power levels so as to
use only the power required
to reach the network. In
general, the closer you are to
a base station, the lower the
power output of the device.
Before a phone model is
available for sale to the
public, compliance with the
European R&TTE directive
must be shown. This directive
includes as one essential
requirement the protection
of the health and the safety
for the user and any other
person.
The highest SAR value for this
device when tested for use at
the ear is 0.976 W/kg.
This device meets RF
exposure guidelines when
used either in the normal
use position against the ear
or when positioned at least
1.5 cm away from the body.
When a carry case, belt clip
or holder is used for bodyworn operation, it should not
contain metal and should
position the product at
least 1.5 cm away from your
body. In order to transmit
data files or messages, this
device requires a quality
connection to the network.
In some cases, transmission
of data files or messages
may be delayed until such
a connection is available.
Ensure the above separation
distance instructions
are followed until the
transmission is completed.
The highest SAR value for this
device when tested for use at
the body is 0.341 W/kg.
7
Guidelines for safe and e cient use
* The SAR limit for mobile
devices used by the public
is 2.0 watts/kilogram (W/kg)
averaged over ten grams of
body tissue. The guidelines
incorporate a substantial
margin of safety to give
additional protection for the
public and to account for any
variations in measurements.
SAR values may vary
depending on national
reporting requirements and
the network band.
For SAR information in other
regions please look under
product information at www.
lgmobile.com.
FCC SAR information
Your mobile device is also
designed to meet the
requirements for exposure to
radio waves established by
the Federal Communications
8LG GT400 | User Guide
Commission (USA) and
Industry Canada.
These requirements set a SAR
limit of 1.6 W/kg averaged
over 1 gram of tissue. The
highest SAR value reported
under this standard during
product certifi cation for use
at the ear is 1.16 W/kg and
when properly worn on the
body is 0.63 W/kg.
Additionally, this device was
tested for typical body-worn
operations with the back of
the phone kept 0.79 inches
(2cm) between the users
body and the back of the
phone.
To comply with FCC RF
exposure requirements,
a minimum separation
distance of 0.79 inches(2cm)
must be maintained between
the user’s body and the back
of the phone.
* FCC Notice & Caution
Notice!
This device complies with
part 15 of the FCC Rules.
Operation is subject to the
following two conditions:
(1) This device may not cause
harmful interference, and
(2) this device must accept
any interference received,
including interference
that may cause undesired
operation.
Caution!
Change or Modifi cations that
are not expressly approved
by the manufacturer could
void the user’s authority to
operate the equipment.
