*2 The band width and the channel which can be used depends on the
installed wireless LAN module. And the approved channels on using are
different at each country or region. When using these channels in any
country or region, refer to the addendum sheet which is Approved
Countries/Regions for use. The channel configuration is managed as
follows:
■ For wireless clients that operate in a Wireless LAN Infrastructure, the
Wireless LAN module will automatically start operation at the channel
identified by the Wireless LAN Access Point. When roaming between
different access points the station can dynamically switch to another
channel if required.
■ For Wireless LAN modules installed in wireless clients that operating in
a peer-to-peer mode, the module will use the default channel 10.
■ In a Wireless LAN Access Point, the Wireless LAN module will use the
factory-set default channel (printed in bold), unless the LAN
Administrator selected a different channel when configuring the
Wireless LAN Access Point device.
