Figure D3-14 Field wireless channels and wireless LAN channels window
Usable wireless channels are regulated by national radio standards. With field wireless, 16 chan-
nels between 11 and 26 can be used. However, the default setting is FCC (US), which removes
channel 26 because it cannot be used. The 15 channels between channel 11 and 25 that are
permitted in most countries are selected. If there is a wireless channel that is not used because of
additional national channel restrictions or the effects of interference with wireless LAN and other
wireless transmissions cannot be tolerated, clear the check box of that channel.
After the hopping pattern settings have been configured and the [Optimization] button is clicked,
a message appears asking the user to confirm that the frequencies used comply with local wire-
less standards.

ure D3-16 appears.
