(2)When the [PTT] key is pressed to enable transmit mode, a
100Hz square w avef orm is int ernally generat ed and
modulated.
(3)While observing the w aveforms on the oscilloscope, turn
the semi-fixed volume (VR6) to adjust the DCS modulation
w aveform to a square w aveform.
(4)When the DCS modulation w aveform becomes a square
w aveform, release the [PTT] key.
