• Avoid placing metal objects on the surface of the wireless charging cradle, as they could cause the equipment to heat up and malfunction. Only use the wireless charging cradle in environments with an ambient temperature ranging from 0°C to 45°C. • If the ambient temperature is too high, the wireless charger may stop working. If this occurs, you are advised to stop wireless charging. • To keep the wireless charger in good condition, avoid using it inside a vehicle. • Adult supervision is advised if children are to use or come into contact with this product. • Switch off your wireless device when requested to do so in hospitals, clinics or health care facilities. These requests are designed to prevent possible interference with sensitive medical equipment. • Some wireless devices may affect the performance of hearing aids or pacemakers. Consult your service provider for more information. • Pacemaker manufacturers recommend that a minimum distance of 15 cm be maintained between a device and a pacemaker to prevent potential interference with the pacemaker. • If using a pacemaker, hold the device on the side opposite the pacemaker and do not carry the device in your front pocket. • Observe local laws and regulations while using the device. To reduce the risk of accidents, do not use your wireless device while driving. • To prevent damage to your device's parts or internal circuits, do not use it in dusty, smoky, damp or dirty environments or near magnetic fields. • Do not use, store or transport the device where flammables or explosives are stored (in a gas station, oil depot, or chemical plant, for example). Using your device in these environments increases the risk of explosion or fire. • Dispose of this device, the battery, and accessories according to local regulations. They should not be disposed of in normal household waste. Improper battery use may lead to fire, explosion, or other hazards. • If the battery leaks, ensure that the electrolyte does not make direct contact with your skin or eyes. If the electrolyte touches your skin or splashes into your eyes, immediately flush with clean water and consult a doctor. • When charging the device, make sure the power adapter is plugged into a socket near the devices and is easily accessible. Unplug the charger from the electric socket and from the device when the device is not used for a long time. • Do not place sharp metal objects, such as pins, near the microphone. The microphone may attract these objects and result in injury. • Wireless devices may interfere with the airplane's flight system. Do not use your device where wireless devices are not allowed according to the airplane company's regulations. • Switch off your wireless device whenever you are instructed to do so by airport or airline staff. Consult the airline staff about the use of wireless devices on board the aircraft, if your device offers a 'flight mode' this must be enabled prior to boarding an aircraft. • To ensure the best audio performance of your device's microphone, use a cloth to wipe the area of the microphone which has been exposed to water. Do not use the microphone until the wet areas are totally dry. • Protect the wearable and its accessories from strong impact, strong vibration, scratches, and sharp objects, these may damage the device. • Make sure that the wearable and its accessories stay clean and dry. Do not wear the wearable too loosely or tightly during workouts. Clean your wrist and device after the workout. Rinse and dry the device to clean it before putting it back on. • If the wearable is built for swimming and showering, make sure to regularly clean the strap, dry your wrist and the device before wearing it again. • Loosen the strap for a little bit during the day to let your skin breathe. If wearing it starts to feel uncomfortable, take off your wearable and let your wrist have a rest. If it still feels uncomfortable, stop wearing it and seek medical advice as soon as possible. You can also purchase straps made from other materials and with different designs from the official Huawei website. • Ensure that the power adapter meets the requirements of IEC/EN 62368-1 and has been tested and approved according to national or local standards. • The device complies with the EN 13319 standard. For details, please refer to the official website or User Guide. Diving-related precautions • Before using the device, make sure that you have received professional diving training, are familiar with how to use the diving equipment, and have read the Quick Start Guide and User Guide carefully. Any improper use of this device or the diving equipment may prove dangerous. • Be sure to receive any necessary medical examinations before diving. If you have any pre-existing or potential health conditions, a doctor's examination may be required. Diving with potential health problems may prove dangerous, and can result in injury. Please take responsibility for your own safety. • For safety reasons, do not dive alone. Please dive with a qualified diver instead. • The device can't be shared among multiple users for diving-related purposes. Data such as diving history, parameters, and real-time depth changes are user-specific. Therefore, sharing this device for dives can lead to inaccurate information, resulting in injury or even death. • Electronic devices can be faulty, and this device is no exception. Please keep track of the current depth, diving duration, gas, partial pressure of oxygen, no-decompression limit (NDL), and other information. Make sure to prepare a backup device, as a single source of information is not sufficient when your safety is on the line. • Before diving, perform safety checks on the device. For example, check whether the device functions properly, whether the diving settings are correct, and whether the battery power is sufficient. • The device should not be used for commercial or professional diving activities. It is intended only for recreational purposes. • The device doesn't take the changing physiological conditions of each individual into account. Even when a dive is performed entirely in accordance with the diving plan set by this device or the diving equipment, there is still a risk of decompression sickness (DCS). No method or equipment can completely rule out the possibility of DCS, nitrogen narcosis, or oxygen toxicity. Therefore, you're advised to always dive within the safety limits provided by the device to minimise potential risks. • The device is capable of estimating your underwater gas consumption based on the gas consumption rate you input in the diving plan, but this value is for reference only and shouldn't be used as the sole basis for your decisions. • Before scuba diving, check the gas composition in the cylinder, and input the correct corresponding values into the device. Failure to do so may output an incorrect diving algorithm, which can pose a serious threat to your safety. • The use of multiple gas mixtures, and/or performing of technical dives that require periodic decompression stops, and/or dives in closed environments can lead to serious injury or even death. • The device automatically calculates altitude changes via a barometer. The pressure data used by the decompression model is not affected by the altitude or water surface pressure. However, when you enter a high-altitude area, your body will actively exhaust nitrogen due to the low atmospheric pressure. Therefore, it is recommended that you reserve at least six hours for this process, in order to ensure that your body is fully adapted to the highaltitude environment. • The basic decompression algorithm model used by the device is the Bühlmann ZHL-16C Algorithm, which creates conservatism levels by using the pressure difference coefficient. The default conservatism setting will vary by diving mode. Do not change the gradient factors (GF) values unless you understand the possible consequences. • The decompression information displayed on the device, including the NDL, stop depth, stop duration, and Time-to-Surface (TTS), are all predictions. These values will vary with external conditions such as current depth, diving duration, and gas composition. In addition, the accuracy of these predictions may be affected by the limitations imposed by the decompression algorithm. For example, an inappropriate ascend rate, switching gas at the wrong time, and ignoring decompression stops can all lead to the display of inaccurate data. 2
