Troubleshooting

Symptom Troubleshooting Explanation

iAUDIO works abnormally or does not play when memory is full.

iAUDIO works abnormally or does not play when hundreds of ﬁles are in the root folder.

Initialize iAUDIO and leave a free space of at least 1-2MB, then try again.

Don’t store many ﬁles in Root folder. Instead, create sub-folders under the root folder, and save ﬁles under sub-folders.

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 damaged during ﬁle transfer, iAUDIO may not work normally.

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

•
