The maximum possible RF signal strength depends on the currently set country-
specific settings for radio systems (see “Selecting the country-specific settings –
“Country Selection“” on page 160). This setting can only be made when “Live”
operating mode is activated.

A table with all the adjustable frequencies and the exact GHz can be found
in the appendix (see page 251).
DFS channels – Dynamic Frequency Selection
DFS channels are unlicensed frequencies in the 5.260 to 5.825 GHz fre-
quency band that can be occupied by authorized primary users.
If one of the DFS channels is used by a primary user (e.g. radar), this channel
cannot be used by the ADN conference system for at least 30 minutes. How-
ever, with both manual and automatic channel selection, the ADN confer-
ence system automatically switches to an alternate channel. Upon expiry of
the legal time frame (30minutes to 24hours), the ADN conference system
will check if the initially selected DFS channel is again available and will use
it if needed.
