Troubleshooting
Symptom Troubleshooting Explanation
iAUDIO works abnormally or
does not play when memory
is full.
Initialize iAUDIO and leave a free
space of at least 1-2MB, then
try again.
An important system file, “settings.
dat” is saved in the Root folder of
the flash memory. If this file is not
saved properly, deleted, or dam-
aged during file transfer, iAUDIO
may not work normally.
iAUDIO works abnormally or
does not play when hundreds of
files are in the root folder.
Don’t store many files in Root
folder. Instead, create sub-folders
under the root folder, and save files
under sub-folders.
iAUDIO uses FAT file system.
Owing to the limitations of FAT, you
are advised not to save many files
in the root directory.
When JetShell is running, it controls iAUDIO. Make sure to exit JetShell before performing
the following tasks:
• Installing iAUDIO’s USB driver
• Formatting iAUDIO
• Upgrading Firmware
