Correct Operation

For safe and comfortable operation, please read carefully and abide by the following 
items:
1.To avoid hearing loss, set the volume of the player to minimum before connecting the 
headset. After putting the earphone on, increase the volume to a proper level. Noise is 
measured in decibels (dB). Any outside noise of 85 decibels or more will cause gradual 
hearing loss.
2.Please pay attention to your operation habits! Volume and time are directly and 
inversely proportional to hearing loss. The louder the volume, the shorter the time you 
listen; the more comfortable the volume is, the longer the time you listen. Listen high 
volume sound will cause damage to your hearing.
