Comply with all safety warnings and
regulations regarding mobile device usage
while operating a vehicle
Do not use your device in a hospital or near medical equipment
that can be interfered with by radio frequency
If you personally use any medical equipment, contact the
manufacturer of the equipment to ensure the safety of your equipment
from radio frequency.
While driving, safely operating the vehicle is your first responsibility.
Never use your mobile device while driving, if it is prohibited by law.
For your safety and the safety of others, practice good common
sense and remember the following tips:
• Use a hands-free device.
• Get to know your device and its convenience features, such as
speed dial and redial. These features help you reduce the time
needed to place or receive calls on your mobile device.
• Position your device within easy reach. Be able to access your
wireless device without removing your eyes from the road. If you
receive an incoming call at an inconvenient time, let your voice
mail answer it for you.
• Let the person you are speaking with know you are driving.
Suspend calls in heavy traffic or hazardous weather conditions.
Rain, sleet, snow, ice, and heavy traffic can be hazardous.
• Do not take notes or look up phone numbers. Jotting down a “to
do” list or flipping through your address book takes attention away
from your primary responsibility of driving safely.
• Dial sensibly and assess the traffic. Place calls when you are not
moving or before pulling into traffic. Try to plan calls when your
car will be stationary. If you need to make a call, dial only a few
numbers, check the road and your mirrors, then continue.
• Do not engage in stressful or emotional conversations that may
be distracting. Make people you are talking with aware you are
driving and suspend conversations that have the potential to divert
your attention from the road.
• Use your device to call for help. Dial a local emergency number in
the case of fire, traffic accident, or medical emergencies.
• Use your device to help others in emergencies. If you see an auto
accident, a crime in progress, or a serious emergency where lives
are in danger, call a local emergency number.

Specific Absorption Rate (SAR) certification
information
Your device conforms to European Union (EU) standards that limit
human exposure to radio frequency (RF) energy emitted by radio
and telecommunications equipment. These standards prevent the
sale of mobile devices that exceed a maximum exposure level
(known as the Specific Absorption Rate, or SAR) of 2.0 W/kg.
During testing, the maximum SAR recorded for this model was
0.881 W/kg. In normal use, the actual SAR is likely to be much
lower, as the device has been designed to emit only the RF energy
necessary to transmit a signal to the nearest base station. By
automatically emitting lower levels when possible, your device
reduces your overall exposure to RF energy.
The Declaration of Conformity statement at the back of this manual
demonstrates your device’s compliance with the European Radio
& Terminal Telecommunications Equipment (R&TTE) directive. For
more information about the SAR and related EU standards, visit the
Samsung website.
