Bug Fixes
The following bugs were fixed.
  • If a forced power-down was carried out at a particular timing, at the next startup, the CD drive became inoperative.
  • In some cases, after mixed recording on an SD card (CD → SD), the CD drive became inoperative and the power could not be turned off.

What you will need to update
  • CD-2u
  • AC Adaptor (PSB-1U)
  • SD card ( 64 MB or larger)
  • A computer with a SD Card Reader/Writer.

Caution when performing the update
  • Never apply this update data to any product other than the CD-2u. This update data may destroy the data or system program of other products.
  • When you update, use an attached AC adaptor as the power source. Never use a battery.
  • If a power failure or similar accident occurs during the update process, the CD-2u won’t be able to start up in normal operating mode. This will require servicing, so you will need to contact Roland service center near you if this occurs.
  • We regret that we are unable to answer questions regarding the update procedure using this system program. Please perform the update responsibly, following the directions given in this document.

Getting the update file
Please open/extract the downloaded "cd2u_sys_v104.zip" file on your computer to get the two update files named "CD2U_MAIN.UPD" in the "cd2u_sys_v104" folder.

Procedure for the update
Creating the Update Card
  • Use a computer with a SD Card Reader/Writer to copy the update files onto the root directory of an SD memory card.
    * Do not copy the "cd2u_sys_v104" folder.
    * Don't LOCK the SD memory card.
    * If you use a commercially available SD card, you must format it on the CD-2u.

Update Procedure
* Be careful never to allow the AC adaptor to be disconnected while the update is in progress. Loss of power before the operation finishes can damage the system and make correct operation impossible.
