Skywarn

The Skywarn function lets you jump directly to the last channel in memory (Channel 200) from any mode by pressing FUNC + . The scanner goes into scan hold mode and starts receiving transmissions in the last channel. If no frequency is programmed in the last channel, No Prg appears and the scanner sounds an error tone.
