Improper use of batteries may result in battery fl uid leakage, overheating, or explosion. Released battery fl uid is corrosive and may be toxic. It can cause skin and eye burns, and is harmful if swallowed.To reduce the risk of injury: ●Keep batteries out of reach of children. ●Do not heat, open, puncture, mutilate, or dispose of batteries in fi re. ●Do not mix new and old batteries or batteries of different types (for example, carbon-zinc and alkaline batteries). ●Do not allow metal objects to touch the battery terminals on the device; they can become hot and cause burns. ●Remove the batteries if they are worn out or before storing your device for an extended period of time. Always remove old, weak , or worn-out batteries promptly and recycle or dispose of them in accordance with Local and National Disposal Regulations. ●If a battery leaks, remove all batteries, taking care to keep the leaked fl uid from touching your skin or clothes. If fl uid from the batter comes into contact with skin or clothes, fl ush skin with water immediately. Before inserting new batteries, thoroughly clean the batter compartment with a damp paper towel, or follow the battery manufacturer's recommendations for cleanup.Disposable (non-rechargeable) batteries only: ●Caution Risk of explosion if battery is replaced by an incorrect type. Use and replace only with correct size and type (alkaline, zinc -carbon, or zinc-chloride) of batteries.Headset DevicesExtended exposure to high volumes when using a headset may result in temporary or permanent hearing loss. To prevent damage to your headset, avoid sitting or stepping on the headset, its cable, or the cable connector.Warning:The earphones contained within this product may attract dangerous objects like staples and paper clips. Take care to avoid harm that may occur from the retention of dangerous objects on the earphones.Wireless DevicesBefore boarding any aircraft or packing a wireless device in luggage that will be checked, remove the batteries from the wirele ss device or turn the wireless device off (if it has an on/off switch). Wireless devices can transmit radio frequency (RF) energy, much like a ce llular telephone, whenever batteries are installed and the wireless device is turned on (if it has an on/off switch).Game Controllers, Keyboards, and Mouse DevicesHealth WarningUse of game controllers, keyboards, mice, or other electronic input devices may be linked to serious injuries or disorders.When using a computer, as with many activities, you may experience occasional discomfort in your hands, arms, shoulders, neck, or other parts of your body. However, if you experience symptoms such as persistent or recurring discomfort, pain, throbbing, aching, tingling, n umbness, burning sensation, or stiffness, DO NOT IGNORE THESE WARNING SIGNS. PROMPTLY SEE A QUALIFIED HEALTH PROFESSIONAL, even if symptoms occur when you are not working at your computer. Symptoms like these can be associated with painful and sometimes permanently d isabling injuries or disorders of the nerves, muscles, tendons, or other parts of the body. These musculoskeletal disorders (MSDs) inclu de carpal tunnel syndrome, tendonitis, tenosynovitis, and other conditions.While researchers are not yet able to answer many questions about MSDs, there is general agreement that many factors may be lin ked to their occurrence, including: overall health, stress and how one copes with it, medical and physical conditions, and how a person posi tions and uses his or her body during work and other activities (including use of a keyboard or mouse). The amount of time a person performs an ac tivity may also be a factor.Some guidelines that may help you work more comfortably with your computer and possibly reduce your risk of experiencing an MSD can be found in the "Healthy Computing Guide" installed with this device's software or in the "Healthy Gaming Guide" available at www. xbox.com. If this device did not come with software, you can access the "Healthy Computing Guide" at www.microsoft.com/hardware or (in th e United States only) by calling (800) 360-7561 to request a CD at no charge. If you have questions about how your own lifestyle, activi ties, or medical, or physical condition may be related to MSDs, see a quali fi ed health professional.English
