Important Safety Instructions Before using the product, read through the instruction manual to ensure that you will use the product correctly. DANGER • Do NOT place the product into contact with fire. • Keep the earbuds and accessories out of the reach of children and pets. Otherwise, it may lead to accidental swallowing or malfunction. • Do NOT disassemble the product. WARNING • Use the earbuds in an environment in which you can ensure the safety of your surroundings because warning sounds and other sounds in your surroundings will be hard to hear. • Do NOT use, store, or leave the product in an environment with excessive humidity, dust, oil fumes, or steam, or in a high-temperature environment near a source of fire, in direct sunlight, or inside a vehicle. • Do NOT use the earbuds when operating a motor vehicle, motorcycle, watercra , or bicycle. Be aware of the surrounding environment when wearing the earbuds. • Do NOT allow water or foreign matter to get inside the product. Otherwise, this may result in a fire or electric shock. If water or foreign matter accidentally gets inside the product, stop using it immediately and contact your distributor. • Do NOT use the earbuds under a blanket or the like. • Do NOT insert the USB connector when the earbuds or USB cable is wet. Inserting a USB connector in a wet state may cause the earbuds to short circuit due to contact with the liquid (tap water, seawater, cold drinks, etc.), and foreign matter entering into the earbuds may result in abnormal heat generation or product failure. • Stop using the earbuds if there is battery leakage or a peculiar smell, and keep the product away from flames. • Use the included USB charging cable to charge your earbuds. NOTE • Do NOT use it for a long time at high volume. Otherwise, your hearing might be damaged. To protect your ears, be careful NOT to turn up the volume too high. In addition, regardless of the volume, extended use will place a burden on your ears. Please rest your ears every hour. • Do NOT use the product near medical equipment. Electromagnetic waves may have an impact on pacemakers and medical electronic devices. • Do NOT use them if the earbuds cause any abnormal sensation against your skin. If your skin condition does not return to normal soon, seek medical attention. • Do NOT touch the earbuds for an extended period during charging. Otherwise, it may result in a low-temperature burn. • Please follow the instructions of the flight attendant when using the product onboard an aircra . Electromagnetic waves may cause the device to malfunction, resulting in an accident. Discarding rechargeable batteries The built-in rechargeable battery this device is equipped with is a renewable resource. Dispose of the product according to local standards and regulations. Do NOT disassemble the product. For customers in the USA FCC Notice You are cautioned that any changes or modifications not expressly approved in this manual could void your authority to operate this equipment. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instruc- tions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment o and on, the user is encouraged to try to correct the interference by one or more of the following measures: • Reorient or relocate the receiving antenna. • Increase the separation between the equipment and receiver. • Connect the equipment into an outlet on a circuit di erent from that to which the receiver is connected. • Consult the dealer or an experienced radio/TV technician for help. This transmitter must not be co-located or operated in conjunction with any other antenna or transmitter. This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment and meets the FCC radio frequency (RF) Exposure Guidelines. This equipment has very low levels of RF energy that is deemed to comply without testing of specific absorption rate (SAR). FCC ID: 2A9B6TE-Y1 Radio interference of Bluetooth® products • Interference from electromagnetic radiation in the surrounding environment, such as that from wireless LAN equipment, microwave ovens, and other electromagnetic cooking appliances may result in noise, loss of sound, or communication being disconnected. • The e ective communication range of Bluetooth® may vary greatly due to the influence of shields (the human body, metal, walls, etc.) and the state of electromagnetic radiation in your surroundings. • The electromagnetic radiation generated by Bluetooth® devices may a ect the operation of other electronic devices. There is a risk of an accident occurring as a result in some cases, so turn o the power of the earbuds and other Bluetooth® devices when in the following places: - Hospitals / near the priority seating on the subway / in the vicinity of gas stations and other places where combustible gas is generated / near fire alarms For long-lasting use • Beware of over-discharge If the rechargeable battery is not charged for a long time, it may lead to over-discharge and deterioration. If storing for a long time, please charge the battery once a month to prevent over-discharge. • Beware of deformation, damag…
