and also when JetShell can communicate with iAUDIO without any problems. If JetShell is not working  
properly, please refer to Appendix A.  
Checking the firmware version  
Check the current version of iAUDIO to find out whether the firmware version needs to be upgraded.  
If the firmware version is identical, you don't need to upgrade it.  
To confirm the firmware version, check the number which appears on the lower right of the LCD window  
when you turn on the power. Number such as 0:03:50 indicates that the current firmware version is 3.50.  
Firmware version is displayed also on the LCD when iAUDIO is connected to your PC.  
Preparation before downloading and installing firmware  
1. Download the latest firmware file provided in iAUDIO web-site(http://www.jnc-digital.com).

2. Make sure the battery is inserted in iAUDIO.  
3. Connect the USB cable to iAUDIO. The "PC Connected" message appears on the LCD.
