cables, which cause too much voltage drop when connected to high current draw equipment like
the X3.
Q: Why does the battery capacity indication not accurate?
Because X3 will judge the battery capacity by the voltage of the battery, so it's not very accurate.
Also the battery voltage might differ while playing music. Therefore, the battery capacity indication
is for reference only.
Q: How to judge the X3's charging status?
A: On the bottom of the front panel, there is a charging indicator LED, which lights up red while
charging and green when fully charged. The battery level of the onscreen battery gauge (on the
upper right corner while the player is on, or taking up the whole screen if the player is off) moves to
indicate battery charging.
Q: How to tell whether the X3 is fully charged or not?
A: When X3 gets fully charged, the status indicator LED on the power button lights up green and the
onscreen battery gauge (on the upper right corner while the player is on, or taking up the whole
screen if the player is off) stops moving and holds steady at full.
2. Transferring songs
Q: What operating systems does the X3 support (for transferring songs)?
A: It supports 32bit and 64bit Windows XP, Windows 7 and above, as well as Mac OS 9, X, and most
versions of Linux and Unix.
Q: What USB ports are the X3 compatible with?
A: The X3 is compatible with USB 2.0 (and all later standards that are backwards compatible with
2.0, including 3.0 and 3.1).
Q: How quickly does the X3 transfer songs?
A: This is dependent on the size of files / songs transferred and the Class of the micro SD card;
average read / write speeds are about 5MB/s.
Q: Why does it transfer so slowly through a front USB port on a desktop computer?
A: The front USB ports on a desktop computer are connected to the motherboard through long thin
cables, which may degrade the signal quality and hence reduce the speed of transfers; it is
recommended to connect to a rear USB port on a desktop computer to transfer data.
