Erasing a License
● Erasing a License
When you invalidate a license option on a temporary basis or when you do not use it for a
long period of time, you can invalidate the function by erasing the license.
The license can be validated by registering the license number again.

When you have entered the service mode, use the right and left arrow keys to display
items,and press the OK key to fix the setting.

(4) Display [SEND].
(5) Press the OK key.

For Reference:
There is no function to display the license registration numbers in the main unit. Therefore,
when there is a possibility to restore the license after erasing it, make sure that a user has
written down the license registration number.
When a license option is displayed in Procedure (4), 001 1 is displayed. The last "1" shows
that the license is validated by license authentication.
After the license is erased, the last number is changed to "2".
When the option is standard, the last number shows "3" which means disable for license
transfer.
Details about the last number:
1: The function is validated.
2: The function is invalidated, or a license is transferred.
3: The function is invalidated, or the license does not exist.
