LED Guide to Indicator Lights Mode Description Indication Power On White LED indicator lights for about 1 second “Power On” Power Off White LED indicator lights for about 1 second “Power Off” Pairing White LED flashes quickly “Pairing” Connected No function operation, the indicator light is off “Paired, Your device is connected” ANC On Green light is on “ANC ON” ANC Off The green indicator is off “ANC OFF” Listen Responsibly To avoid hearing damage, make sure that the volume on your music player is turned down before connecting your headphones. After placing headphones in/on your ears, gradually turn up the volume until you reach a comfortable listening level. Noise levels are measured in decibels (dB), exposure to any noise at or above 85 dB can cause gradual hearing loss. Monitor your use; hearing loss is a function of loudness versus time. The louder it is, the less time you can be exposed to it. The softer it is, the more time you can listen to it. Get the most out of your equipment and enjoy great audio performance even at safe levels. Our headphones will allow you to hear more details at lower volume levels than ever before. Learn how to establish a safe listening level and review other important safety guidelines from the Consumer Electronics Association at www.ce.org. Important information on how to prevent Noise-Induced Hearing Loss (NIHL) and a comprehensive list of which noises can cause damage can be found on the Deafness Research Foundation’s website, www.drf.org. FCC Statement Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.
