The NuraBuds have been designed and tested for safety and comfort, but please note: exposure to any noise of 85 Decibels (dB) or above (approximately the same volume as a food blender) can cause gradual hearing loss. Due to the clarity and noise cancelling of the NuraBuds, you won’t need to listen to your music as loudly as with many conventional headphones. Monitor your use. Hearing loss is a function of loudness versus time — the louder the volume, the less time you can be exposed to it. The quieter the volume, the longer you can listen. For example, 8 hours at 85 dB causes as much damage as 4 hours at 88 dB, 2 hours at 91 dB, or just 15 minutes at 100 dB. Only use the NuraBuds with the volume set at a comfortable, moderate level. Do not listen to music at a high volume for any extended period. Be aware that reminders or warning sounds, i.e. alarms, message tones and incoming calls, might vary while using the NuraBuds. If you experience a warming sensation or loss of hearing, remove the NuraBuds from your head immediately and contact Nura support. If the NuraBuds emit a loud or unusual noise, stop using it and contact Nura support immediately. Due to noise-cancelling technology, do not use the NuraBuds at any time when an inability to hear may present a danger to yourself or others. For example, while driving, riding a bicycle, in a If you’re using the NuraBuds for phone calls while driving, then use caution and follow applicable laws using a single earpiece while driving. Charging the NuraBuds should be done only by following the instructions in this user manual. Do not make unauthorised alterations to this product. Any attempt to do so will void the warranty. CAUTION the battery shall not be exposed to excessive heat such as sunshine, or the like. DISPOSE OF USED BATTERIES ACCORDING TO THE INSTRUCTIONS result in an explosion.

FCC ID: 2ANIN-T0BBL According to KDB 447498 D01 General RF Exposure Guidance v06, section 4.3.1 At 100 MHz to 6 GHz and for test separation distances ≤ 50 mm, the SAR test exclusion threshold is determined according to the following [(max. power of channel, including tune-up tolerance, mW) / (min. test separation distance, mm)] x [√f(GHz)] ≤ 3.0 1. SAR test exclusion threshold Frequency: 2480MHz (min. separation distances = 5 mm) SAR test exclusion thresholds (5 mm) = 3 x 5 / (√ 2.480) = 9.525 mW Max. Tune-up Tolerance (mW) SAR Test Exclusion Thresholds (5mm) (mW) 8 9.525 Calculation Value: 8 (mW) / 5 (mm) x √ 2.480 = 2.52 So, Calculation value ≤ 3.0 Remark: -Max. conducted power 7.9 mW is closet 8 mW, so 8 mW was calculated. -When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion. 2. Conclusion: No SAR is required.
