Choking Hazards, Repetitive Motion

Choking Hazards

iPhone contains small parts, which may present a choking hazard to small children. Keep iPhone and its accessories away from small children.

Repetitive Motion

When you perform repetitive activities such as typing on iPhone, you may experience occasional discomfort in your hands, arms, shoulders, neck, or other parts of your body. If you continue to have discomfort during or after such use, stop use and see a physician.

Potentially Explosive Atmospheres

Turn o∂ iPhone (press and hold the Sleep/Wake button, and then slide the onscreen slider) when in any area with a potentially explosive atmosphere. Do not charge iPhone, and obey all signs and instructions. Sparks in such areas could cause an explosion or ﬁre, resulting in serious injury or even death.

Areas with a potentially explosive atmosphere are often, but not always, marked clearly. Potential areas may include: fueling areas (such as gas stations); below deck on boats; fuel or chemical transfer or storage facilities; vehicles using liqueﬁed petroleum gas (such as propane or butane); areas where the air contains chemicals or particles (such as grain, dust, or metal powders); and any other area where you would normally be advised to turn o∂ your vehicle engine.

For Vehicles Equipped with an Air Bag

An air bag inﬂates with great force. Do not store iPhone or any of its accessories in the area over the air bag or in the air bag deployment area.

Exposure to Radio Frequency Energy

iPhone contains radio transmitters and receivers. When on, iPhone receives and sends out radio frequency (RF) energy through its antenna. The iPhone antenna is located on the back of iPhone near the dock connector. iPhone

is designed and manufactured not to exceed limits for exposure to RF energy set by the Federal Communications Commission (FCC) of the United States. The exposure standard employs a unit of measurement known as the speciﬁc absorption rate, or SAR. The SAR limit applicable to iPhone set by the FCC is 1.6 watts per kilogram (W/kg). Tests for SAR are conducted using standard operating positions (i.e., at the ear and worn on the body) speciﬁed by the FCC with iPhone transmitting at its highest certiﬁed power level in all tested frequency bands. Although SAR is determined at the highest certiﬁed power level, the actual SAR level of iPhone while in operation can be well below the maximum value because iPhone adjusts its cellular transmitting power based in part on proximity to the wireless network. In general, the closer you are to a cellular base station, the lower the cellular transmitting power level.

iPhone has been tested,2 and meets the FCC RF exposure guidelines for cellular, Wi-Fi, and Bluetooth® operation. When tested for use at the ear, iPhone’s highest SAR value is 0.974 W/kg. When tested for body-worn operation, with iPhone positioned 5/8 inch (15 mm) from the body, iPhone’s highest SAR value is 0.694 W/kg. For body-worn

2The device was tested by an accredited laboratory according to measurement standards and procedures speciﬁed in FCC OET Bulletin 65, Supplement C (Edition 01-01) and IEEE P1528.1, April 21 2003.
