Instructions for wearing and use This product should be stored in a cool and dry place. The operating temperature is �-��°C. Please use a soft dry cloth for daily cleaning. Never disassemble your headphones at any time, as doing so may damage the headphones or cause the battery to self-ignite.Keep the product away from heat sources or other corrosive liquids, and avoid using or placing it in any high-temperature places. If any part of this product is damaged or hot, please stop using this product immediately.Avoid exposing the headphones to rain or immersion in liquids. If not used for a long time, please charge them again before use. Storage and maintenance Listening to music at too high a volume may damage your hearing and the sound may be distorted. Hearing Damage It is recommended that the power provided by the charger must be between the minimum [�.�] watts and the maximum [�.�] watts required by the radio device to achieve maximum charging speed. Charging Safety Tips Do not use this product in places where wireless devices are prohibited or inappropriate (for example, airports in some areas, medical facilities, etc.). Otherwise, it may interfere with other electronic devices or cause other dangers. Some electronic devices may malfunction due to radio interference from this product (for example, some automotive electronic devices).Please contact the manufacturer of the electronic device for details. This device complies with part �� of the FCC Rules. Operation is subject to the following two conditions: (�) This device may not cause harmful interference, and (�) this device must accept any interference received, including interference that may cause undesired operation. Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part �� 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 instructions, 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 off 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 different from that to which the receiver is connected. -- Consult the dealer or an experienced radio/TV technician for help. The device has been evaluated to meet general RF exposure requirement. The device can be used in portable exposure condition without restriction. Electromagnetic Interference Tips FCC Caution: Headphone Function ControlHeadphone Function Control Please NotesCommon Problems Your headset can be used with devices that support the Bluetooth version and features of that headset. Wireless telephones and wireless network devices such as these devices may cause interference, which typically sounds like static noise.Please do not place headphones near other devices that use or emit radio waves. Headphones produce far less interference than regular cell phones, so don't worry about the When the headset is docked to a Bluetooth cell phone, an encrypted link is established between the two devices, making it difficult for devices other than the headset to listen in. Adjust the headphone volume, or move to another area and try again. Wipe with a dry, soft cloth. The headset and travel charger may not be connected, reconnect and charge the headset. Available functions may vary depending on the connected device. Will my headset work with laptops, desktop computers and PDAs? Why do I hear static or interference during a call? Do headphones interfere with electronic devices, radios or computers in the car? Can other Bluetooth cell hone users hear my calls? Why do I hear an echo during a call? How do I clean my headphones? Headphones won't fully charge? I am unable to use some of the features described in.
