Trunking Modes
In Closed mode, the scanner stops only on transmissions with saved
and unlocked Talk Group IDs. This lets you focus a scan on the
frequencies you have identied, ignoring other transmissions.
In Open mode, the scanner stops for transmissions on any unlocked
channel. This lets you search for Talk Group IDs that you can then
save.
While scanning, “–” appears for Closed mode and “+” appears for
Open mode under the channel storage bank’s number. When the
scanner stops on a channel,”OPEN” or “CLOSED” appears.
