Repetitive motion When you perform repetitive activities such as typing or playing games on iPod touch, you may experience occasional discomfort in your hands, arms, wrists, shoulders, neck, or other parts of your body. If you experience discomfort, stop using iPod touch and consult a physician.

High-consequence activities This device is not intended for use where the failure of the device could lead to death, personal injury, or severe environmental damage.

iPod touch loop (available on some models) To attach the loop securely, press the button on the back of iPod touch to pop it up, slip the loop tab over the button, then pull the loop to snap it into place. Certain activities when using the iPod touch loop may pose a risk of injury, especially if the loop becomes caught or trapped—for example, while working around machinery. Don’t swing iPod touch while using the loop, as the loop might come off, causing injury or damage.

Choking hazard Some iPod touch accessories may present a choking hazard to small children. Keep these accessories away from small children.

Important handling information

Cleaning Clean iPod touch immediately if it comes in contact with anything that may cause stains—such as dirt, ink, makeup, or lotions. To clean:

Disconnect all cables and turn iPod touch off (press and hold the Sleep/Wake button, then slide the onscreen slider).

Use a soft, lint-free cloth.

Avoid getting moisture in openings.

Don’t use cleaning products or compressed air.

The front of iPod touch is made of glass with a fingerprint-resistant oleophobic (oil repellant) coating. This coating wears over time with normal usage. Cleaning products and abrasive materials will further diminish the coating, and may scratch the glass.

Using connectors, ports, and buttons Never force a connector into a port or apply excessive pressure to a button, because this may cause damage that is not covered under the warranty. If the connector and port don’t join with reasonable ease, they probably don’t match. Check for obstructions and make sure that the connector matches the port and that you have positioned the connector correctly in relation to the port.

Lightning cable Discoloration of the Lightning plug after regular use is normal. Dirt, debris, and exposure to liquids may cause discoloration. To remove the discoloration or if the cable becomes warm during use or won’t charge or sync your iPod touch, disconnect the Lightning cable from your computer or power adapter and clean it with a soft, dry, lint-free cloth. Do not use liquids or cleaning products when cleaning the Lightning connector.

Operating temperature iPod touch is designed to work in ambient temperatures between 32° and 95° F (0° and 35° C) and stored in temperatures between -4° and 113° F (-20° and 45° C). iPod touch can be damaged and battery life shortened if stored or operated outside of these temperature ranges. Avoid exposing iPod touch to dramatic changes in temperature or humidity. When you’re using iPod touch or charging the battery, it is normal for iPod touch to get warm.
