Listening caution

Do not play your headphones or earphones at a high volume.

Hearing experts advise against continuous extended play.

If you experience a ringing in your ears, reduce volume or discontinue use.

Do not use while operating a motorized vehicle. It may create a traffic hazard and is illegal in many areas.

You should use extreme caution or temporarily discontinue use in potentially hazardous situations.

Even if your headphones or earphones are the open-air type designed to let you hear outside sounds, don't turn up the volume so high that you can't hear what's around you.

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:

Start your volume control at a low setting.

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.

Precautions:

1). When not using the player for an extended period of time, remove the batteries to avoid damage due to leakage. (Apply to Models that come with AAA or AA battery)
2). Do not use the player in extremely hot, cold, dusty or damp environments.
3). Make sure the HOLD key is in the unlock position before using the player (otherwise controls will not function).
4). Avoid dropping or striking the unit. This may cause external and internal physical damage to the player.
5). Replace battery with new one if: (Apply to Models that come with AAA or AA battery) a) The battery level icon displays

(An empty battery)

b) The players powers off automatically and off again when restarted.
c) No response when pressing keys with HOLD off and battery installed

6). To prevent damage from static shock, never use the player in very dry conditions.
7). When player is being formatted or transferring a file, do not interrupt the connection. Otherwise, data may be corrupt of lost.
8). When the player is used as a portable HD, please use only per instructions. Otherwise, permanent data loss could occur.
