safety and usage information
Comply with the following precautions to avoid dangerous or illegal situations and ensure peak performance of your mobile phone.

Safety warnings

Keep your phone away from small children and pets
Keep your phone and all accessories out of the reach of small children or animals. Small parts may cause choking or serious injury if swallowed.

Protect your hearing

Listening to a headset at high volumes can damage your hearing. Use only the minimum volume setting necessary to hear your conversation or music.
Install mobile phones and equipment with caution
Ensure that any mobile phones or related equipment installed in your vehicle are securely mounted. Avoid placing your phone and accessories near or in an air bag deployment area. Improperly installed wireless equipment can cause serious injury when air bags inflate rapidly.
Never place batteries or phones on or in heating devices, such as microwave ovens, stoves, or radiators. Batteries may explode when overheated. Never crush or puncture the battery. Avoid exposing the battery to high external pressure, which can lead to an internal short circuit and overheating.
Handle and dispose of batteries and chargers with care
Use only Samsung-approved batteries and chargers specifically designed for your phone. Incompatible batteries and chargers can cause serious injuries or damage to your phone. Never dispose of batteries or phones in a fire. Follow all local regulations when disposing of used batteries or phones.
Avoid interference with pacemakers
Maintain a minimum of 15 cm (6 inches) between mobile phones and pacemakers to avoid potential interference, as recommended by manufacturers and the independent research group, Wireless Technology Research. If you have any reason to suspect that your phone is interfering with a pacemaker or other medical device, turn off the phone immediately and contact the manufacturer of the pacemaker or medical device for guidance.

Turn off the phone in potentially explosive environments
Do not use your phone at refuelling points (service stations) or near fuels or chemicals. Turn off your phone whenever directed by warning signs or instructions. Your phone could cause explosions or fire in and around fuel or chemical storage and transfer areas or blasting areas. Do not store or carry flammable liquids, gases, or explosive materials in the same compartment as the phone, its parts, or accessories.
Do not use the phone if the screen is cracked or broken
Broken glass or acrylic could cause injury to your hand and face. Bring the phone to a Samsung service centre to replace the screen. Damage caused by careless handling will void your manufacturers warranty.
Reduce the risk of repetitive motion injuries
While using your phone, hold the phone with a relaxed grip, press the keys lightly, use special features that reduce the number of keys you have to press (such as templates and predictive text), and take frequent breaks. 3

Safety precautions

Drive safely at all times
Avoid using your phone while driving and obey all regulations that restrict the use of mobile phones while driving. Use hands-free accessories to increase your safety when possible.
Turn off the phone near medical equipment
Your phone can interfere with medical equipment in hospitals or health care facilities. Follow all regulations, posted warnings, and directions from medical personnel.
Follow all safety warnings and regulations
Comply with any regulations that restrict the use of a mobile phone in a certain area.
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.
Use only Samsung-approved accessories
Using incompatible accessories may damage your phone or cause injury. 4
Protect the phone and batteries from damage
Avoid exposing your phone and batteries to very cold or very hot temperatures (below 0 C/32 F or above 45 C/113 F). Extreme temperatures can cause the deformation of the phone and reduce the charging capacity and life of your phone and 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.

Specific Absorption Rate (SAR) certification 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 Specific Absorption Rate, or SAR) of 2.0 watts per kilogram.
During testing, the maximum SAR recorded for this model was 0.684 watts per kilogram. 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. The Declaration of Conformity at the back of this manual demonstrates your phones compliance with the European Radio & Terminal Telecommunications Equipment (R&TTE) directive. For more information about the SAR and related EU standards, visit the Samsung mobile phone website.

Cautions for sunlight charging Do not connect to the phone to a travel adapter or USB cable while charging by sunlight. Do not leave the phone in an enclosed car for a long time, as the phone may overheat. Charging the battery when it is overheated may cause fire, deformation, breakdown, or malfunction of the phone. Do not expose the solar panel to sunlight for a long time to avoid very hot temperatures. Especially, do not leave your phone in a heated vehicle for a long period of time. This may damage the phone or battery. Do not charge the battery using a halogen or infrared lamp. This may cause fire or explosion. Do not focus sunlight on the solar panel with a mirror, lens, or eye glasses. This may overheat the phone and consequently cause fire, deformation, breakdown, or malfunction of the phone. 19
Do not use the phone if the solar panel is cracked or broken. Broken glass could cause injury to your hand and face. Bring the phone to a Samsung service centre to replace the solar panel. Notes for sunlight charging When the phone is off, 1 hour of sunlight at about 80,000 lux (approximately the amount of sunlight at noon on a sunny day) charging will provide approximately 5-10 minutes of talk time. Talk time may vary depending environmental factors, such as weather, region, altitude of the sun, or signal strength. Sunlight is a secondary power source. To ensure a fully-charged, use the travel adapter. Sunlight charging is not possible in the following situations:
- Near a window that blocks direct sunlight - In high or low temperatures
- If any part of solar panel is covered - If you attach a protection film or ornaments to the solar panel or scribble or write on it
While wearing the phone on your neck, the battery may not charge efficiently due to indirect sunlight. The battery cannot be charged by artificial light. Always keep the solar charging point and the solar panel clean.
Insert a memory card (optional)
To store additional multimedia files, you must insert a memory card. Your phone accepts microSD or microSDHC memory cards up to 16 GB (depending on memory card manufacturer and type). Formatting the memory card on a PC may cause incompatibility with your phone. Format the memory card only on the phone.
