Owner’s Guide Bedienungsanleitung Guía del usuario Notice d’utilisation Manuale di istruzioni COWIN SE9 ANC Wireless Headphones IMPO R T ANT S AFETY INSTRUCTIONS Please read and keep all safety and use instructions. WARNINGS/CAUTIONS • Do NOT use the headphones at a high volume for any extended period. – To avoid hearing damage, use your headphones at a comfortable, moderate volume level. – Turn the volume down on your device before placing the headphones in/on your ears, then turn the volume up gradually until you reach a comfortable listening level. • Do NOT use your headphones while driving for phone calls or any other purpose. • Do NOT use the headphones with noise cancelling on at any time the inability to hear surrounding sounds, it may present a danger to yourself or others, e.g., while riding a bicycle or walking in or near traffic, a construction site or railroad, etc. – Remove the headphones, or use the headphones with noise cancelling off and adjust your volume, to ensure you can hear surrounding sounds, including alarms and warning signals. – Be aware of how sounds that you rely on as reminders or warnings may vary in character when using the headphones. • Do NOT use the headphones if they emit any loud unusual noise. If this happens, turn the headphones off and contact COWIN customer service. • Remove headphones immediately if you experience a warming sensation or loss of audio. • Do NOT use mobile phone adapters to connect headphones to airplane seat jacks, as this could result in injury or property damage due to overheating. • 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. – The headphones are not engineered for noise conditions, altitude, temperature or other environmental conditions common in non-commercial aircraft, resulting in possible interference to critical communications. • To reduce the risk of fire or electrical shock, do NOT expose this product to rain, liquids or moisture. • Do NOT make unauthorized alterations to this product. • Use this product only with an agency approved power supply which meets local regulatory requirements (e.g., UL, CSA, VDE, CCC). • Do NOT expose products containing batteries to excessive heat (e.g. from storage in direct sunlight, fire or the like). Contains small parts which may be a choking hazard. Not suitable for children under age 3. This product contains magnetic material. Consult your physician on whether this might affect your implantable medical device. ENGLISH 2 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. COWIN Corporation hereby declares that this product is in compliance with the essential requirements and other relevant provisions of Directive 2014/53/EU and all other applicable EU directive requirements. For Europe: Frequency band of opera�on 2400 to 2483.5 MHz: Bluetooth: Maximum transmit power less than 20 dBm EIRP. Bluetooth Low Energy: Maximum power spectral density less than 10 dBm/MHz EIRP. Changes or modifications not expressly approved by COWIN Corporation could void the user’s authority to operate this equipment. This device complies with part 15 of the FCC Rules and with Industry Canada license-exempt RSS standard(s). Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation This device complies with FCC and Industry Canada radiation exposure limits set forth for general population. It must not be co-located or operating in conjunction with any other antenna or transmitter. Meets IMDA Requirements. CAN ICES-3 (B)/NMB-3(B) Management Regulation for Low-power Radio-frequency Devices Article XII According to “Management Regulation for Low-power Radio-frequency Devices” without permission granted by the NCC, any company, enterprise, or user is not allowed to change frequency, enhance transmitting power or alter original characteristic as well as performance to an approved low power radio-frequency devices. Article XIV The low power radio-frequency devices shall not influence aircraft security and interfere legal communications; if found, the user shall cease operating immediately until no interference is achieved. The said legal communications means radio communications operated in compliance with the Telecommunications Act. The low power radio-frequency devices must be susceptible with the interference from legal communications or ISM radio wave radiated devices. DON’T attempt to remove the rechargeable lithium-ion battery from this product.…

FCC ID: 2AB5T-SE9 Portable device According to §15.247(e)(i) and §1.1307(b)(1), systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess of the Commission’s guidelines. According to KDB447498 D01 General RF Exposure Guidance V06 The 1-g SAR and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)]·[√f(GHZ)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR, where: • f(GHZ) is the RF channel transmit frequency in GHz • Power and distance are rounded to the nearest mW and mm before calculation • The result is rounded to one decimal place for comparison When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion.
