differentoperatingchannelsforeachcollocatedRADWINunit.
• IfoneormorecollocatedunitsarenotRADWINunits,ensurethatthereisaphysical
separationofatleastthreemetersbetweenaRADWINunitandanyothercollocated
radioonthesite.
• Usethelargestpossiblefrequencygapbetweentheseunits.
• Choosethebestfrequencychannel(asclearaspossibleforminterference).Youmay
havetousetheChangeBandfacilityavailableforallRADWIN2000products.
• Toselectafrequencychannel,movethelinktoInstallationMode(usingSiteconfigura‐
tion)andstarttheInstallationwizard.IntheChannelSettingswindow,usethequality
