Product information guide
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 liqueed 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.
Using Connectors and Ports Never force a connector into a port. Check
for obstructions on the port. If the connector and port don’t join with
reasonable ease, they probably don’t match. Make sure that the connector
matches the port and that you have positioned the connector correctly in
relation to the port.
Accessories and Wireless Performance Not all iPod accessories are
fully compatible with iPhone. Turning on Airplane Mode on iPhone may
eliminate audio interference between iPhone and an accessory. While
Airplane mode is on, you cannot make or receive calls or use features that
require wireless communication. Under some conditions, certain accessories
may aect iPhone wireless performance. Reorienting or relocating iPhone
and the connected accessory may improve wireless performance.
Keeping iPhone Within Acceptable Temperatures iPhone is designed
to be operated in temperatures between 0º and 35º C (32º to 95º F) and
stored in temperatures between -20º and 45º C (-4º to 113º F). Low- or
high-temperature conditions might temporarily shorten battery life or
cause iPhone to temporarily stop working properly. Leaving iPhone in
a parked vehicle or in direct sunlight can cause iPhone to exceed these
storage or operating temperature ranges. Avoid dramatic changes in
temperature or humidity when using iPhone as condensation may form
on or within iPhone.
When you’re using iPhone or charging the battery, it is normal for iPhone
to get warm. The exterior of iPhone functions as a cooling surface that
transfers heat from inside the unit to the cooler air outside.
Exposure to Radio Frequency Energy iPhone contains radio
transmitters and receivers. When on, iPhone receives and sends out radio
frequency (RF) energy through its antennas. The iPhone cellular antenna
is located at the bottom edge of iPhone. The Wi-Fi and Bluetooth®
antenna is located at the top edge of iPhone.
For optimal mobile device performance and to be sure that human
exposure to RF energy does not exceed the FCC guidelines, always follow
these instructions and precautions: When on a call using the built-in
audio receiver in iPhone, hold iPhone with the dock connector pointed
down toward your shoulder to increase separation from the antenna.
When using iPhone near your body for voice calls or for wireless data
transmission over a cellular network, keep iPhone at least 15 mm
(5/8 inch) away from the body, and only use carrying cases, belt clips, or
holders that do not have metal parts and that maintain at least 15 mm
(5/8 inch) separation between iPhone and the body.
iPhone is designed and manufactured to comply with the 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 specic absorption rate, or SAR. The SAR
limit applicable to iPhone set by the FCC is 1.6 watts per kilogram (W/kg).
