Meter: SWR can be read out directly without calibration. Low insertion loss structure of the meter allows it to be connected permanently. The white scales are for power measurement. Power range 0W - 60W. The orange scales are for SWR measurements.
Frequency Range: 140MHz - 150MHz and 430MHz - 450MHz.
Range Switch: Low is for 0W - 15W and High isd for 15W - 60W.
Frequencies 2m/70cm, Max 60W (see specs).
Function Switch: Selects measurement function between RF power and SWR.
