Controls Aerial conduction Sound directly conducted to the auditory nerve of the brain through bone External auditory canal Eardrum Eardrum Auditory nerve of brain Cochlea Internal auditory canal Principles of bone conduction Most of the sound we hear is the result of sound waves passing through our eardrum to make it vibrate so that the sound waves can be conducted to the internal au- ditory canal. The other way is that the sound waves are directly con- ducted to the internal auditory canal through the vibrat- ion of the bone instead of eardrum. This is another way of people hearing their own sound and this sound con- duction is called bone conduction. How to wear Hang the headphone behind your neck with both speakers clinging to your cheekbones. After that, a- djust it until you feel comfortable. 音乐播放时间-------------标准状态：5小时 待机时间---------------- 20天 充电时间-----------------2小时 BT版本-------------------5.0 喇叭阻抗-----------------10Ω±3db 麦克灵敏度--------------- -38±3db 产品重量-----------------26g 连接距离-----------------15米 充电电压-----------------5V 充电电流-----------------300毫安时 产品规格 重要说明 ·本款耳机骨传导扬声器的正确佩戴位置为耳朵 前方的面颊骨处，请勿将骨传导扬声器置于耳内； ·长时间听大音量的音乐可能会带来不适感，请 尽可能使用中等左右的音量，避免长时间使用大 音量； ·无论音量大小，使用耳机都将影响您对周围环 境声音的感知，使用耳机时多加注意； ·切勿抛扔、坐压耳机或将其浸入水中； ·耳机应远离火、水和高压设备； ·不适合三岁以下儿童使用，包含小零件； ·请勿将其归类为生活垃圾，而将其送往当地相 应的电器电子设备回收站； 若用户因违反以上警告内容造成的人身财产损失， 本公司不承担任何责任 Specifications Music play time--------------Standard: 5 hours Standby time----------------------20 days Charging time---------------------2 hours BT version--------------------------5.0 Speaker impedance--------------10Ω±3db Microphone sensitivity-----------38±3db Product weight---------------------26g Connection distance--------------15 meters Charging voltage------------------5V Charging current------------------300 mAh ----- Attentions ·Please wear the bone-conduction speakers of the headphone at your cheekbones before your ears and do not put them in your ears. ·Listening to music for an excessive long time mayake you feel uncomfortable, please try to use a medium volume instead of a big one. ·No matter how the volume is, please do not make it prevent you from hearing the surrounding sounds.

RF Exposure Requirements Product Description: Buletooth Headphone Model No.: BH528 FCC ID: 2AQ9RBH528 According to the KDB 447498 D01 v06 section 4.3.1, for 100 MHz to 6 GHz and test separation distances ≤ 50 mm, the 1-g and 10-g SAR test exclusion thresholds are determined by the following: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] ꞏ [√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 calculation17 - The result is rounded to one decimal place for comparison Calculation Result: Tx frequency range: 2402-2480MHz Min. test separation distance: 5mm Maximum Conducted Output Power: 4.690dBm Tune-Up output power: 5dBm RF channel transmit frequency: 2441MHz Result: 1.0 Limit: 3.0 The exclusion thresholds is 1.0 < 3, so the transmitter complies with the RF exposure requirements and the SAR is not required.
