Invalidating the License for Transfer to a Different
Device data recovery method
Here the keys required to invalidate the license for transfer to a different device will be
described. The following is not an explanation of how to validate such license.
'Invalidating the License for Transfer to a Different Device' can be executed in the Service
Mode in order to make accessories validated by the license information available to another
host machine.
License history data is required when invalidating the license for transfer to a different device.
License history data is stored threefold in 3 different locations - HDD, Counter PCB, and
SRAM on the Main Controller.
Once the HDD and / or Main Controller are replaced with new ones, it may not be possible
to invalidate the license for transfer to a different device for options validated by the license
information.
License key history data
License history data is used in order that the transferred license key cannot be used in the
same iR host machine again.
-License history data has a total of the number of the iR accessory license key and the MEAP
applications and only 30 of the total are doubly stored in HDD and the counter board.
-Only 30 of the total are doubly stored. The rest is stored in HDD only.
When HDD is broken
If turning on the power of the iR host machine after the replacement of HDD, max. 30 items of
license key/transferred license key history data are automatically recovered in HDD from the
license key history data on the counter board.
Lost license key history, which has been stored only in HDD, becomes as follows:
-The transfer license key cannot be issued to unrecoverable license key history.
-The transfer license key for unrecoverable license key history of the license key that the
transfer license key has been issued is not displayed in service mode.

When Counter board is broken
If turning on the power after the replacement of the counter board due to the breakage,
following operations are performed.
-Automatically recovered from the SRAM on the main controller board.
-If it is impossible that the history is automatically recovered from SRAM to the counter board,
the license key/transfer license key history data is automatically recovered to the counter
board from the license key history data on HDD.
When HDD and Counter board are broken
Recover the data from SRAM to the counter board. Then, recover the data from the counter
board to HDD.
When the data cannot be recovered from SRAM to the counter board, all history data of
license key/transfer license key will be lost.
The accessories continue to be available even in such cases, although 'Invalidating the
License for Transfer to a Different Device' cannot be executed.
