20. Notice

- Make sure all keys are enabled before operation. If they are locked, hold down the MENU and VOL- button to unlock them. - Please charge the battery immediately when the display indicates low battery, or the device will be powered off automatically. - Please disconnect the player from PC properly to avoid data loss. - The transfer rate displayed on the PC may be different depending on the operating system. Exact transfer rate should be subject to the player's indication.

21. Listening Cautions

- Do not play your earphones or headphones 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: 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.

22. 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. 2). Do not use the player in extremely hot, cold, dusty or damp environments. 3). Make sure the keys are unlocked 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).

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.
