Temporary 
enabling of an 
option
You have the possibility of enabling software options with a temporary code 
number for a limited time. You can define a time between 10 to 90 days for 
enabling the software options. However, each option can only be enabled 
once with a temporary code number.
If you want to enable a software option temporarily on the control via the 
temporary key, proceed in the same way as for the standard enabling of 
software options. Press the Set Option button or the SET OPTION soft key. 
This opens a window in which you can enter the code number for the desired 
software option in Enter Key Code.
If the software option was enabled successfully, the expiration date of the 
temporary enabling is shown in the Expires column under SIK Options. After 
the defined period has expired, the entry in the Expires column will change to 
EXP, meaning "expired." The software option is then no longer available.
A software option can be enabled for an unlimited period at any time by means 
of the code number, which you will receive from HEIDENHAIN after stating 
the SIK number.
HEIDENHAIN would like to point out that it is not possible to use the OEM-
specific options with the SIKs of the first generation. If you encounter any 
problems in this respect, please contact your HEIDENHAIN service agency.
You can generate the temporary code number with the TNCOEMOption tool 
for PCs. The tool is available for cost-free download from our HEIDENHAIN 
FileBase.
When you generate the code number, you must specify the number of the 
respective software option, the number of days you want to enable the option, 
and an optional OEM Key. The OEM Key provides protection against 
unauthorized persons generating code numbers for your machines with the 
help of the PC tool in order to enable software options without your approval. 
However, it is not essential to specify an OEM Key.
The OEM Key for generating the code number must be identical to the OEM 
Key on your control.
