CLEANING & USAGE INSTRUCTIONS Always handle your device with care to maintain its appearance. To clean, wipe the outer surface with a soft, lint-free cloth. This symbol identifies safety and health messages in this guide. WARNING: Read safety and health information Microsoft products are developed to be safe and effective. Please read this guide for important safety and health information about your device and for the terms of the Limited Warranty that applies to your device. The guide is intended to help you be more comfortable and productive while using this device. Failure to follow the instructions for proper set up, use, and care for your device can increase the risk of serious personal injury, death, or property damage. You can find additional support at support.microsoft.com or on the Surface App for Surface devices. NOTICE: Read use instructions Failure to properly set up, use, and care for this product can increase the risk of damage to your device.

X22-17423-01_BRO.indd 227.08.19 16:45 3 NOTICE: Heat related concerns for wearable devices Your device may become very warm during normal use. It complies with the user-accessible surface temperature limits defined by the International Standards for Safety (IEC 60950-1 and IEC 62368). To reduce heat-related concerns, follow these guidelines: • Use CAUTION when operating your device with a pillow, blanket or other soft material contacting the device, because the material can block the airflow which may result in the device overheating. • If your device gets uncomfortably warm, remove it and take a break. • If your device is used for long periods, its surface can become very warm. While the temperature may not feel hot to the touch, if you maintain physical contact with the device for a long time, your skin might suffer a low-heat injury. • Never place the power supply unit (PSU) for your device on furniture or any other surface that might be marred by exposure to heat since the surface of the PSU may increase in temperature during normal use. CAUTION: Device stability Do not place your device on uneven or unstable surfaces. Be sure to hold it securely when it is carried and not via an accessory, cable, or cord. Failure to hold your device securely could cause it to fall or hit a person or object, which could damage your device, damage other property, or cause personal injury. WARNING: Choking hazard This device may contain small parts that may be a choking hazard to children under 3 years. Keep small parts away from children. WARNING: Keep out of the reach of small children Your device and its accessories are not toys. Do not allow small children to play with them because children could hurt themselves or others or damage your device. Keep your device and all its parts and accessories out of the reach of small children. WARNING: High‑risk use Your device is not designed or intended for use in any application or situation where failure of any kind of the device could lead to death, serious bodily injury, or severe environmental damage (“high-risk use”). If you elect to use your device for a high-risk use, you do so at your own risk. X22-17423-01_BRO.indd 327.08.19 16:45 4 CAUTION: Skin irritation This device is made of materials commonly used in wearable consumer electronic devices. However, certain people may develop skin irritation due to allergies or sensitivities. To reduce the risk of skin irritation: • Clean your device regularly. • Avoid using lotions or other products under the portions of the device that contact your skin. • Do not wear over injured skin. • Where applicable, tighten the adjustment until snug, but not uncomfortably tight. • If your skin becomes irritated, stop using device. If symptoms are severe or persist, consult your physician. CAUTION: Hearing safety Frequent or extended exposure to loud noise or sounds when using a headset or headphones can cause temporary or permanent hearing loss. Individual susceptibility to noise-induced hearing loss and potential hearing problems varies. Also, the sound volume produced by a device may vary depending on the nature of the sound, device settings, and the headset or headphones used. As a result, there is no single volume setting that is appropriate for everyone or for every combination of sound, settings, and equipment. Here are a few common-sense recommendations to minimize your exposure to loud noises or sounds when using a headset or headphones with your device: • Minimize your time listening to loud sound. All of the sound you are exposed to each day adds up. At maximum volume, listening to music or other content on your device with a headset or headphones can permanently damage your hearing in 15 minutes. If you are exposed to other loud sounds also, it takes less time listening at high …
