 Sound can be deceiving. Over time your hearing “comfort level”adapts to higher volumes

of sound. So what sounds “normal”can actually be loud and harmful to your hearing. Guard

against this by setting your equipment at a safe level BEFORE your hearing adapts.

To establish a safe level:

a. Start your volume control at a low setting.

b. Slowly increase the sound until you can hear it comfortably and clearly, and without

distortion. Once you have established a comfortable sound level, leave it there.

21. Precautions

1). When not using the player for an extended period of time, please charge the battery at least

once per month to extend the battery life.
