~ 14. Zoom - This control is used with the A, V, and Reset
keys to set the Zoom range. To initiate this mode, press the Zoom
key once, and the vertical zoom cursor will appear on the right side
of the screen. Set the desired Zoom range by moving the cursor with
the A and v, then press the Zoom key again. The Zoom range scales
appear with a digital numeric display, Zoom mode starts, and an
expanded (zoomed) chart appears over the whole of the screen. The

mode by pressing the Zoom key, and then either the A or V keys to
