2AJRD-ISOTUNESISOtunes ORIGINAL 2.0

Models IT-19 ORIGINAL 2.0 EN 352 IT-20 ORIGINAL 2.0 Important Please read, understand, and follow all safety information. This product is designed to protect against harmful noise. Fitting ISOtunes® ORIGINAL 2.0 comes with 4 sets of TRILOGY™ foam eartips (XS,S,M,L) and 3 sets of silicone eartips (S,M,L). Choose the size that fits most snugly in your ear canal. Remember, the snugger the fit, the better the noise blocking. The silicone eartips are intended for use when NOT in noisy situations. ISOtunes® TRILOGY™ foam eartips have a threaded core and the sound port on the earbud is also threaded. 1. Twist the foam eartip counterclockwise to remove and clockwise to place on a new foam eartip. 2. Carefully compress the foam eartip on the stem/sound port. 3. Insert the foam/eartip into your ear as deeply as is comfortable and hold for 5 seconds while the foam expands. 4. Repeat with second eartip. Hint: To open your ear canal wider, lift the top of your ear up and away from your head, as shown in FIG1. Introduction Thank you for purchasing ISOtunes® ORIGINAL 2.0 Professional Noise Isolating headphones. These headphones have been specifically designed for use in noisy environments – allowing you to block out much of the surrounding noise so that you can listen to your music or talk on the phone with less interruption. This product has been tested and meets the European Safety Standard EN352-2:2002 and the ANSI & NIOSH standards for a hearing protector, with a Single Number Rating (SNR) of 36 dB and a Noise Reduction Rating (NRR) of 27 dB. Full testing details are available in the Noise Attenuation section of this booklet. Noise Attenuation APPROVAL: ISOtunes® ORIGINAL 2.0 is tested and approved in accordance with ANSI S3.19-1974 Specifications and the European Safety Standard EN 352-2:2002. ANSI S3.19-1974 The level of noise entering a person’s ear, when ISOtunes® ORIGINAL 2.0 headphones are worn as directed, is closely approximated by the difference between the A-weighted environmental noise level and the Noise Reduction Rating (NRR). Improper fit of this device will reduce its effectiveness in attenuating noise. Consult the enclosed instructions for proper fitting. A1: Frequency (Hz) A2: Mean Attenuation (dB) A3: Standard Deviation (dB) Example: 1. The surrounding noise level measured at the ear is 100 dB. 2. The NRR of ISOtunes® ORIGINAL 2.0 is 27 dB. 3. The noise level entering the ear is approximately equal to 73dB. Please note that the NRR is based on the attenuation of continuous noise and may not be an accurate indicator of the protection attainable against impulsive noise, such as gunfire. EN352 B1: Frequency (Hz) B2: Mean Attenuation (dB) B3: Standard Deviation (dB) B4: Assumed Protection Value (APV) (dB) B5: H = Hearing protection estimation for high frequency sounds (f ≥ 2000Hz) M = Hearing protection estimation for medium frequency sounds (500 Hz < f < 2000Hz) L = Hearing protection estimation for low frequency sounds (f ≤ 500Hz) The EU declaration of conformity can be accessed at www.isotunes.co.uk/EU-declaration-of-conformity The products will be certified to the Product standard EN 352-2:2002 and the PPE Regulation 2016/425 SafeMax™ Technology ISOtunes® ORIGINAL 2.0 incorporates SafeMax™ Technology, therefore its volume output has been limited to 85 decibels (IT-20) and 79 decibels (IT-19). ISOtunes® devices with SafeMax™ Technology are OSHA, NIOSH, and ANSI compliant and, when designated, meet the European Safety Standard EN352. Cleaning and Maintenance Trilogy foam eartips are disposable. To ensure peak performance, we recommend replacing TRILOGY™ Foam Tips every three months or when they become soiled. In order to purchase additional tips, please go to www.ISOtunes.co.uk Clean your ISOtunes® ORIGINAL EN352 by gently wiping them with a clean damp cloth. Mild soap can be applied to the cloth. Do not use abrasive cleaning solvents to clean the headset. Avoid scratching the headset with sharp objects, as this may cause damage. Keep the headset away from high temperature areas. • Clean your ISOtunes ORIGINAL 2.0 by gently wiping them with a clean, damp cloth with mild soap. • Do not use abrasive cleaning solvents to clean the hearing protector. The TRILOGY™ foam eartips should be regularly inspected for deterioration, cracking, or other damage. The eartips can be cleaned in between uses with a damp cloth and water. Overtime, the eartips should be replaced. WARNINGS ISOtunes® ORIGINAL 2.0 does an excellent job of blocking outside noise. As such, ISOtunes® ORIGINAL 2.0 should NOT be used in environments where users need to be fully aware of their surroundings for personal safety reasons. For example, do NOT use them while driving a car or riding a motorcycle. Similarly, do NOT use them when riding a bicycle outside.
