Many countries specify the channel range and power limits for Wi-Fi devices operated
within their borders, and these limits are set automatically in the RCM5400W in firmware
according to the country or region. For example, only channels 1–11 are authorized for use
in the United States or Canada, and so channels 12 and 13 are disabled. See Section 6.2.4.1
for additional information and sample programs demonstrating how to configure an end
device to meet the regulatory channel range and power limit requirements. Table 5 pro-
vides additional information on which channels are allowed in selected countries. Any
attempt to operate a device outside the allowed channel range or power limits will void
your regulatory approval to operate the device in that country.
