In the case with the spectrophotometer you can find everything you need to install and use Color Match Explorer :

> The spectrophotometer
> two standards (BLACK and WHITE) to calibrate the tool
> a CD-ROM with the colour retrieval program (Lechler Color Match Explorer®)
> a printed user manual; you can find its electronic version in installation CD-ROM                                          
> an USB cable to connect the tool to your Personal Computer
> 4 AA batteries of 1,5 V (not recheargable) to power the tool
> a hardware key: it seems a common USB key, but this one contains the licence to use the software and you cannot use it to save files.

PLEASE NOTE
To use Color Match Explorer it is necessary that the hardware key is connected to the computer where the program is installed.
