Jak to "rozpracowac"

Note: The Wireless File Transmitter is available in two versions depending on your region. Both are identical other than their number of wireless radio channels: the WFT-E3 supports 13 channels, while the WFT-E3(A) supports 11 to comply with regulations in the USA and Canada, just like other wireless networking devices. Since this is the only difference, we’ll refer to both as the WFT-E3 for clarity from this point on. Our WFT-E3 was running firmware 1.0.0, while the EOS 40D ran 1.0.3. At the time of writing, the WFT-E3 was only compatible with the EOS 40D, although the WFT-E2 transmitter for the 1Ds Mark III offers the same features in a different package.

Ktora wersja jest na rynek Europejski, Polski?
Jak rozumiec ta roznicy, czy w Polsce nie ma kompatybilnych urzadzen z wersja na rynek USA/Kanada?
