1. File Contents

The executable file pmp500_firmware_216.exe is a self-
extracting compressed file, which when expanded, will place 
two files on your computer.  Typically, the files will be
extracted to a folder labeled C:\Rio500\Firmware , unless the 
user has changed this defualt setting.  These two files are:

Rio500Flash_216.exe - This is the utility which communicates with 
the Rio500 hardware and uploads the firmware file to the Rio.  
The upgrade utility is version 1.00.

Readme.txt - This is the text file you are now reading.

===============================================================

2. Instructions

Note:  This upgrade will erase the contents of the Rio500.

2.1   Run the self-extracting file pmp500_firmware_216.exe 
      which you downloaded from the Internet.
2.2   Connect the Rio500 to the computer with the USB cable.
2.3   Turn the Rio500 on.
2.4   Double click on the Icon labeled 'Rio500Flash_216.exe'
2.5   Click on the button labled 'Start' Acknowledge the pop-up
      window that the internal memory will be reformatted.
2.6   The utility will begin to upload the new firmware file to 
      the Rio500.  Important:  Do not close the program or 
      remove the USB cable during the middle of the upgrade.
2.7   When the upgrade is complete, cycle power to the Rio 
      (off/on). After cycling power, pressing refresh on the 
      utility will show the new firmware version on the player.
2.8   Close the utility. The Rio500 is now ready to receive and
      play MP3 files and Audible files.  
===============================================================

3. Known Issues:

- If in step 2.7, the firmware version still displays the old
  firmware code, it will be necessary to modify the upgrade 
  sequence. This primarily effects users who have upgraded 
  using a beta version firmware.

  Repeat the procedure again, except that when step 2.6 is 
  complete, repeat steps 2.5 and 2.6 a second time, before 
  proceeding to step 2.7 (cycling power).
