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 effective 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 affect the operation of other electronic devices. There is a risk of an accident occurring as a result in some cases, so turn off 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, damage, and impacts: The earbuds and their accessories, such as earpieces, may be deformed or damaged if they are subject to stress for a long time. Please exercise care when storing them. In addition, avoid dropping the product or subjecting it to strong impacts, as it contains precise electronic components.
• Splash-proof specification: The earbuds adopt a splash-proof design but are not completely waterproof. Do NOT intentionally wet the earbuds or put them in a pocket soaked with sweat or rain, otherwise, it may lead to product failure. Wipe off stains containing water or moisture using a soft dry cloth as soon as possible, and use the product in as dry a state as possible. Note that the charging case is not splash-proof.
• Cleaning: Do NOT use chemicals such as benzine, thinner, or alcohol when cleaning the earbuds. Otherwise, the earbuds may be deformed or damaged.

Battery Charging

(Please charge it first before use for the first time)

Charging the charging case

Diagram Description: Shows a charging port, with a USB Type-C connector from a cable being inserted. The cable connects to a USB (A) end, which is then connected to a 5V AC adapter (not included).

• The color of the battery indicator changes to white (70-100%), orange (30-69%), or red (0-29%) depending on the remaining battery capacity.
• Charging may not be possible if the voltage becomes higher or lower than the specified voltage.
• If a charger other than a 5V AC adapter is used, the charging may be stopped by the protection function.
• If charging is not successful, confirm that the USB Type-C® cable is in a normal state and try to recharge it again with a 5V AC adapter.
• Please charge the charging case regularly. (Recommended frequency: at least once a month)

Charging the earbuds
