Power off press the power button for 5seconds. incoming call answer /end press the power button once. Reject a call- Connect press and hold the power button for 2 seconds. Music play /pause press the power button once Volume increase press the plus key once. Volume reduction press the minus key once. Skip to next song long press the volume+ key for 2 seconds. Back to forward song long press the volume- key for 2 seconds. Voice assistant press the power button three times continuously Call back the last number long press the power button for 3 seconds. Bluetooth/TF card mode switching: press the volume+ button twice continuously (If the headphones didn’t build in memory card, it will automatically jump back to the Bluetooth mode. But if the headphones built in memory card, songs will give priority to play the songs in the memory card when it is turned on. When you want to listen to the songs from the mobile phone, you must switch to the Bluetooth mode). Swit ch Chinese and English prompt tone: after it is connected, double-click the volume+ button twice to switch to Bluetooth pairing mode, and then press the power button twice before connecting. 2. Bluetooth pairing instructions Press and hold the power button for 5 seconds until the led indicator flashes red and blue alternatively. I t means the headphones enter the pairing mode. Turn on the Bluetooth function of the mobile phone (or the device enabled Bluetooth function) and search the pairing Name:"Regular". The mobile phone(and the device with Bluetooth function)can be connected successfully by clicking pairing. After the first pairing is completed successfully, the subsequent boot will automatically connect the last paired mobile phone (or the device with Bluetooth function) only if the Bluetooth of the mobile phone(and devices with Bluetooth function) is turned on. FCC Statement This device complies with Part 15 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. Warning: 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 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 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. RF warning statement: -The device has been evaluated to meet general RF exposure requirement. The device can be used in portable exposure condition without restriction. Caution! Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. Reminder To prevent the headphones from automatically turning on the Bluetooth connection, it is recommended that you turn off the Bluetooth function of the device when the headphone is not in use, so as not to consume the power of the headphones and the device.
