Firmware Upgrade
The firmware on the DAR-01 can be upgraded by simply inserting a memory card with the update file
present. The latest firmware will always be available from our website at www.marilynsystems.com.
To upgrade the firmware in your player, please use the following procedure:
1. Copy the firmware file (DAR01.MSF) to the root directory of the card. DO NOT place it in a folder
as it will not be found by the bootloader. Do not rename the file or change any file attributes.
2. With the DAR-01 powered off, insert the memory card.
3. Power the DAR-01. Both LEDs will begin to flash. Be patient as the upgrade process can take up
to a minute.
4. Once the update is complete, the unit will boot normally.
