Troubleshooting Guide: Naxa NPB-250
I cannot play MP3s.
If you have a disc with MP3 files, there are several reasons it may not play even
though you can see the files on a computer. Make sure to do the following
when making an MP3 CD:
1) Make sure that there are only MP3 files on the disc. If there are any
other types of files, the disc may not play.
2) Make sure that you have MP3 files and not a different type of digital
music file. On your computer, right-click the file and select Properties
(or Get Info) to view info about the file.
3) Make sure that you finalize the disc after burning.
4) Make sure that the disc is made with the ISO/Joliet file system.
There are many computer programs that can make CDs. Your computer may
already have one. Please refer to the instructions provided by the computer
program author to learn more about making CDs.
MP3 playback is skipping or
otherwise distorted.
MP3 files encoded at a very high or very low sample rates may not play
properly. (A typical CD-quality file is encoded at 192 Kbps and 44,100 Hz. Try
playing a different file).
The MP3 file may have become corrupted. Try playing a different file.
The player will not recognize
my disc.
The disc may not be loaded securely. Center the disc on the black spindle and
then press down gently until the disc clicks into place.
The disc may be incompatible with the player. This player supports CD-audio,
CD-R/RW, and MP3 CD discs.
Homemade discs must be finalized and mastered with the ISO/Joliet file system.
The disc is skipping or
otherwise distorted.
The disc may be scratched, dirty or otherwise damaged. Damaged discs play
unpredictably.
The batteries may be running low. Try connecting the unit to AC power or using
new batteries.
The USB port is not working.
The USB port is designed to work with USB flash memory drives. It will not work
with devices that require additional power (for example, an MP3 player or hard
disk drive).
The flash drive may be formatted for use with a computer and not a device.
Make sure that your flash drive uses the standard FAT or FAT32 file system
format. The player will not be able to read files from computer formats such as
HFS or NTFS.
The batteries are not working.
The batteries may be running low. Try using new batteries.
The batteries may be installed improperly. Make sure that the positive "+" and
negative "-" ends of the batteries match the markings found inside the battery
compartment.
The AC power cord may still be attached. Disconnect the power cord from the
player.
