5.4 Preparing the file
To create the file, one can use an ordinary text editor (like Windows Notebook). The file
must be saved as a pure text file (.txt). Should other programmes be used (e.g. Microsoft
Word) one must be careful to save the document as "text only": otherwise, control
characters would be inserted which would make it impossible for Security Player to
interpret this file.
5.5 Memorising the files in the flash memory
The configuration file and all the MP3 audio files can be memorised in the flash memory
via a special USB reader/writer for PC.

Security Player allows for the following audio adjustments:
adjustments general pre-amplified output.
