completed. Depending on memory size, this process can take several minutes. The
main key then lights up green or purple, depending on whether the write protection is
activated (purple) or deactivated (green).
Access to the data previously stored on the stick is no longer possible.

5.6 Deleting the crypto keys

Deleting and/or destroying the crypto keys can be carried out in two ways.
a) Destruction by generating new cryptographic keys.
During this process the old encryption keys are irreversibly overwritten. Access to
previously stored data is no longer possible.
This method is a quick way to destroy the data stored on the stick without having to
connect it to a PC.
b) Destruction of the cryptographic keys by exceeding the permitted number of
unsuccessful attempts to enter the user PIN.
During this process, in addition to resetting the user PIN back to the factory settings, the
old cryptographic keys are irreversibly destroyed and new ones generated. Access to all
previously stored data is also no longer possible in this case.

5.7 Time-out and quick-out functions

The administrator can define after how many minutes the activated KOBRA Stick is
automatically locked if neither reading nor writing access to the stick takes place within
the specified time. The lock time can be selected between 1 and 30 minutes. To remove
the lock, press "0".
To set the time-out function:
1) Make sure that you are in menu mode. (The main key lights up blue and the other
keys white.)
2) Press the "8" key, then press "√". The main key flashes purple and all other keys
remain active.
3) Enter the admin PIN and confirm with "√"
4) Enter a number from 0 to 30 and confirm with "√".
