After about three seconds the VM700A displays the touch screen calibration
display. Full instructions for calibration are given on the screen. A small circle
with a dot (1 pixel) is lit in each corner, one corner at a time (top left, top right,
bottom left, bottom right). Hold your finger on the touch screen directly over the
dot until the VM700A beeps, and lights the dot in the next corner. When the
calibration is completed, the VM700A finishes the power-up sequence, then the
Waveform mode display appears.
