your computer. See [Details] on battery duration.
Note
If you charge the player when it has not been used for a long period, your computer may not recognize the player, or nothing may appear on the display. Charge the player for about 5 minutes, after which it should start operating normally again.
Charge the battery in an ambient temperature of between 5 ºC to 35 ºC (41 ºF to 95 ºF). If
you try to charge the battery in an ambient temperature outside this range, the 
icon may appear, and charging cannot be performed.
The number of times the battery can be recharged before it is used up is approximately 500 times. This number may vary, depending on the conditions under which you use the player. The battery indicator on the display is only an estimate. For example, one section of black in the indicator will not always indicate exactly
[Do not disconnect.] appears in the display while the computer accesses the player. During this time, do not disconnect the USB cable (supplied); otherwise, data being transferred (or data already in the player) may be damaged.
The control buttons on the player become inoperative while it is connected to a computer. To prevent battery deterioration, charge the battery at least once every half a year or every year.
Some USB devices connected to the computer may interfere with proper operation of the player.
We do not guarantee battery recharging using a personally assembled/modified computer. If the computer enters a power saving mode, such as the Sleep or Hibernation mode, while the player is connected via the USB cable, the player’s battery will not be charged. Instead, the player continues to draw power from the battery, discharging it.
Do not leave the player connected for extended periods to a laptop computer that is not connected to AC power, since the player may discharge the computer’s battery.
While the player is connected to a computer, do not turn on, restart, wake up from sleep mode, or shut down the computer. These operations may cause the player to malfunction. Disconnect the player from the computer before performing these operations.
Heat may build up in the player while charging. This is not a malfunction.
After connecting to a computer with the USB cable, the resume information of the last played song, video, photo, etc., is cleared. Reselect the desired content from the list screen.
