This readme covers MicroTrack Firmware v1.4.0



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

Installation Instructions:



1) Connect the MicroTrack 24/96 to your Mac or PC (Please refer to your
manual for details on this procedure).



2) Copy the three files, "PP5020.mi4", "BL_MPR.rom" and
"Resources.arl," onto a properly formatted Compact Flash card in the
root directory of your MicroTrack 24/96 (Do not put them in a folder).



3) Properly unmount the MicroTrack 24/96 from the computer (Again,
please refer to your manual for complete instructions).



4) On the MicroTrack 24/96, navigate to Main Menu System Firmware
Update and press the NAV button.



5) You will be asked to verify this action. Press the NAV button again
to begin the firmware update. The MicroTrack will show a few messages
on the screen while the update is in progress. The four LEDs around the
level controls will flash sequentially during the update. When the
firmware update is complete, the MicroTrack will automatically reboot.
To verify the firmware update was executed, go to Main Menu System
Version. If the firmware update was successful, it should now show
Firmware 1.4.0 and Bootloader 1.02

Issues addressed by this release



-Sometimes wouldnít use the entire available space of the media and
would report media full before it actually was. Even after deleting
previous recordings from the media.



-Sometimes reported incorrect file sizes on MP3s.



-Outputs would turn off during playback of some files.



-Autosplit feature would not always record to full 2GB file size when
source is S/PDIF



-Files sometimes were not saved properly if the battery would run out
during a recording.



-Sometimes would revert to default settings if the battery charge were
to run out during use.



-Recordings would sometimes stop early (before filling media or
reaching 2GB) when using S/PDIF as the source.



-Some French characters and translations were incorrect.



-Would not always display the full media message when it should.



-Could not play files from the ëFilesí menu if the files were inside a folder.



-Sometimes would hang on writing very short (less than 1 second) recordings.



-Some S/PDIF recordings failed to start recording if they immediately
followed an analog recording.

User Interface change:



While charging with the unit in the Application, the battery icon will
contain the letters CHG. This will remain until the battery voltage
reaches 100% and remains there for one hour. At that time, the CHG will
be replaced with a plug icon (indicating it is plugged in and supplying
power but no longer charging the battery). This one hour ëtimerí will
be reset only if power is removed for longer than 3 minutes (which will
prevent the unit from overcharging if the power is removed and returned
for short periods of time).
