This Important Product Information Guide contains safety, handling, disposal and recycling, regulatory, and software license information, as well as the one-year limited warranty for iPad.. Keeping iPad Within Acceptable Temperatures Operate iPad in a place where the temperature is between 0º and 35º C (32º to 95º F). Low- or high-temperature conditions might temporarily shorten battery life or cause iPad to temporarily stop working properly. Avoid dramatic changes in temperature or humidity when using iPad, as condensation may form on or within iPad. Store iPad in a place where the temperature is between -20º and 45º C (-4º to 113º F). Don't leave iPad in your car, because temperatures in parked cars can exceed this range. When you're using iPad or charging the battery, it is normal for iPad to get warm. The exterior of iPad functions as a cooling surface that transfers heat from inside the unit to the cooler air outside. Keeping the Outside of iPad Clean  Handle your iPad with care to maintain its appearance. If you are concerned about scratching or abrasion, you can use one of the many cases sold separately. To clean iPad, unplug all cables and turn off iPad (press and hold the Sleep/Wake button, and then slide the onscreen slider). Then use a soft, slightly damp, lint-free cloth. Avoid getting moisture in openings. Don't use window cleaners, household cleaners, aerosol sprays, solvents, alcohol, ammonia, or abrasives to clean iPad. iPad has an oleophobic coating on the screen; simply wipe iPad's screen with a soft, lint-free cloth to remove oil left by your hands. The ability of this coating to repel oil will diminish over time with normal usage, and rubbing the screen with an abrasive material will further diminish its effect and may scratch your screen.
