I am looking for a qtek 9000 device to buy.
My HP 48GX calculator run a self-diagnostic test when are pressed, at
the same time, 3 keys: ON + A + F.
If the hardware is 100% ok the test return "ok".
Are available on the QTEK 9000 a similar routine to check if the
device is working 100%, without any hardware problem?
If not, a third part software for this is available?
