CAUTIONARY NOTES
When executing the Test mode with system 1.xx, never install the TDW-20.
Executing the Test mode on a TD-20 of system 1.xx while the TDW-20 is installed will delete the WAVE data stored in the TDW-20, making subsequent recovery
impossible. When using the TDW-20, first upgrade the TD-20 to version 2.00 or later, and then execute the Test mode.
With system version 2.00 or later, the system cannot be started unless the TDW-20 is installed.
The system in TD-20 units of version 2.00 or later is not merely the successor of version 1.xx, but is a special system program for use in combination with the
TDW-20 expansion board. For this reason, a TD-20 unit of version 2.00 or later cannot run unless the TDW-20 is installed.
* If necessary, the unit can be returned to version 1.xx by employing the method for Updating with CompactFlash (p. 23).
Obtain the system program for version 1.xx from Service Net.
When servicing a unit of system version 2.00 or later, refer to the Service Notes for the TDW-20 as
well.
With version 2.00 or later, the procedure for starting the Test mode is changed, and Test-mode items for the TDW-20 have also been added.
For more details, refer to the TDW-20 Service Notes (#17058576E0).
Verifying the Program Version
As noted above, matters such as the method used to verify the version and the procedures for the Test mode differ according to the program version.
First verify the version, referring to the steps described below.
