channelstobeadded,upto80Channels.
Thissimplymeansthatthenewnarrowbandradioyouhavepurchased
willhavemorechannelsthanolderradios.Pleaserefertotheguidelines

Interference / Poor Audio
Whenanewnarrowbandradioreceivesasignalfromanolder
widebandradiothespeechmaysoundloud.
NarrowbandradiosoperatingonCH41-CH80mayencounter
interferencefromanearbywidebandradiostransmittingonhigh
poweronanadjacentchannel(frequency).
Whenanolderwidebandradioreceivesasignalfromanew
narrowbandradiothespeechmaysoundquiet-thewidebandradio
usersimplyadjuststheirradiovolumeforbestperformance.
Theabovesituationsarenotafaultoftheradiobutasymptomofmixed
widebandandnarrowbandradiosincurrentuse.Itisexpectedthatas
olderwidebandradiosarephasedoutthisissuewillbeeliminated.
