although SOCC are not allowed to tell CFS appliances to change to MFS talkgroup,,,, any appliance responding into there area should do so, and tell SOCC that they are. upon returning to CFS area, the radio should go back to either regional talkgroup to advise SOCC of the appliances return or the loval TG if a station is open, to advise them.
there is no need to listen to CFS tg while at an incident in MFS area, unless the brigades have there own private arrangements.
