 safety and usage information

Turn off the phone or disable the wireless 

functions when in an aircraft

Your phone can cause interference with aircraft 

equipment. Follow all airline regulations and turn off 

your phone or switch to a mode that disables the 

wireless functions when directed by airline personnel.

Protect batteries and chargers from damage

Avoid exposing batteries to very cold or very hot 

• 

temperatures (below 0° C/32° F or above 45° C/

113° F). Extreme temperatures can reduce the 

charging capacity and life of your batteries.
Prevent batteries from contacting metal objects, 

• 

as this can create a connection between the + and 

– terminals of your batteries and lead to temporary or 

permanent battery damage.
Never use a damaged charger or battery.

• 

Handle your phone carefully and sensibly

Disassembling your phone may cause an electric 

• 

shock.
Do not allow your phone to get wet—liquids can 

• 

cause serious damage and will change the color 

of the label that indicates water damage inside 

the phone. Do not handle your phone with wet 

hands. Water damage to your phone can void your 

manufacturer's warranty.

Avoid using or storing your phone in dusty, dirty areas 

• 

to prevent damage to moving parts.
Your phone is a complex electronic device—protect 

• 

it from impacts and rough handling to avoid serious 

damage.
Do not paint your phone, as paint can clog moving 

• 

parts and prevent proper operation.

If your phone has a camera fl ash or light, avoid using it 

• 

close to the eyes of children or animals.
Your phone may be damaged by exposure to magnetic 

• 

fi elds. Do not use carrying cases or accessories with 

magnetic closures or allow your phone to come in 

contact with magnetic fi elds for extended periods of 

time.

Avoid interference with other electronic devices

Your phone emits radio frequency (RF) signals that 

may interfere with unshielded or improperly shielded 

electronic equipment, such as pacemakers, hearing 

aids, medical devices, and other electronic devices in 

homes or vehicles. Consult the manufacturers of your 

electronic devices to solve any interference problems 

you experience.

Important usage information

Use your phone in the normal position

Avoid contact with your phone's internal antenna.

Internal antenna

Allow only qualifi ed personnel to service your 

phone

Allowing non-qualifi ed personnel to service your phone 

may result in damage to your phone and will void your 

warranty.

Specifi c Absorption Rate (SAR) certifi cation 

information

Your phone 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 

phones that exceed a maximum exposure level (known 

as the Specifi c Absorption Rate, or SAR) of 2.0 W/kg.

During testing, the maximum SAR recorded for this 

model was 0.568 W/kg. In normal use, the actual 

SAR is likely to be much lower, as the phone 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 

phone reduces your overall exposure to RF energy.
For more information about the SAR and related EU 

standards, visit the Samsung mobile phone website.

Safety precautions
