4.4 System Lock
⚫ “Security Breach” Lock
For the protection of proprietary right and intellectual property of EZDS that are
embodied in Z5, the product contains the “Security Breach Lock” function.
In the event of executing any diagnostic functions of Z5 in a way that is not logically
possible in the real world, and when such abuse is detected evidently, it is considered
as a serious security breach and Z5 is programmed to lock down its system
immediately for self-protection.
In case the Z5 is locked down for this reason, no unlock code input is possible and the
only way to unlock the device is returning the device to the EZDS in Korea for
inspection. It will be unlocked only when the device turns out to have been locked for
no proper reasons. If the internal memory is altered or manipulated by the user from
the state when the Z5 was locked, any request for unlocking the device will be refused.
⚫ Violation of end user license agreement for regional restriction
As written in the first page of this manual, and as it appears on the screen in the
process of registering Z5, the product is licensed for use in the designated country only.
Z5 found being used outside the designated country can be locked down as it
constitutes a direct violation of end user license agreement.
Once Z5 is locked for this reason, it is not recoverable unless the Z5 base unit is
returned to the authorized local distributor in the region where the Z5 is actually being
used.
The Z5 can be unlocked only by inputting the unlock code which is provided with the
consent of the authorized local distributor in the regional of actual use. And this
unlocking process itself is not subject to warranty and cost may be charged because it
will involve the transfer of responsibility of service and support to the new local
distributor and change of software license.
