don't say "apparat" when you can say "device".

side note, when first transistor-based portable radios showed up (as opposed to large lamp-based stationary devices), they were called "transistor". you would take not your portable radio with you, it was your transistor.

I actually wanted to write "apparatus"; not sure if this would be any better though :)
