Turn the volume down on your device before placing the earphones in your ears, then turn the volume up gradually until you reach a comfortable listening level. Do NOT use your earphones while driving or at any time the inability to hear surrounding sounds may present a danger to yourself or others. The charging case and earphones shall not be exposed to excessive heat such as sunshine, fire or the like. Focus on your safety and that of others if you use the earphones while engaging in any activity requiring your attention, e.g., while riding a bicycle or walking in or near traffic, a construction site or railroad, etc. Remove the earphones or adjust your volume to ensure you can hear surrounding sounds, including alarms and warning signals. Do NOT use the headphones as aviation communication headsets except in case of emergency. No incoming audio will be heard with a discharged or improperly installed battery. This could result in the potential of missed communications while piloting an aircraft. Extremely loud ambient noise levels common to many propeller-driven aircraft may impair your ability to receive incoming audio communications, particularly during takeoff and climb out. Mezger AC-1 earphones are not engineered for noise conditions, altitude, temperature or other environmental conditions common in non-commercial aircraft, resulting in possible interference to critical communications. Do NOT place naked flame sources, such as lighted candles, on or near the product. Do NOT make unauthorized alterations to the product; doing so may compromise safety, regulatory compliance, system performance, and may void the warranty. In the event of a battery leaking, do not allow the liquid to come in contact with the skin or eyes. If contact has been made, wash the affected area with copious amounts of water and seek medical advice. FCC statement This device complies with Part 15 of the FCC Rules.
