Firmware (FW) version 002.520.006 or 004.420.021 (built 2005.02) 
===================================


Why should I upgrade?
=================
- This upgrade allows your Key audio player to play secure WMA music files purchased from online music services 
  (please check music playing rights with your music provider).
- This upgrade applies only if your Key audio player is currently running Firmware versions older than version 002.520.006 or 004.420.021.
  Your key Audio player may be with either the chipset ST3505 or ST3410. The installer may auto check the device's chipset and then install the correct version of firmware either 
  002.520.006 for ST3505 or 004.420.021 for ST3410. That's mean after the upgrade you will find the firmware of your device to be either 002.520.006 or 004.420.021 depends on 
  the chipset inside your player.
