Working with the TNCguide
Calling the TNCguide
There are several ways to start TNCguide:
„ Press the HELP key if the TNC isn’t already showing an error
message.
„
Click the help symbol at the lower right of the screen beforehand,
then click the appropriate soft keys.
„
Use the file manager to open a help file (chm file). The TNC can open
any .chm file, even if it isn’t saved on the TNC’s hard disk.
For many soft keys there is a context-sensitive call through which you
can go directly to the description of the soft key’s function. This
functionality requires using a mouse. Proceed as follows:
8 Select the soft-key row containing the desired soft key.
8 Click with the mouse on the help symbol that the TNC displays just
above the soft-key row: The mouse pointer turns into a question
mark.
8 Move the question mark to the soft key for which you want an
explanation, and click: The TNC opens the TNCguide. If no specific
part of the help is assigned to the selected soft key, the TNC opens
the book file main.chm, in which you can use the search function
or the navigation to find the desired explanation manually.
If one or more error messages are waiting for your
attention, the TNC shows the help directly associate with
the error messages. To start the TNCguide, you first have
to acknowledge all error messages.
When the help system is called on the programming
station or the dual-processor version, the TNC starts the
internally define standard browser (usually the Internet
Explorer), and on the single-processor version browser
adapted by HEIDENHAIN.
