This is the zoom size menu. Zoom size is the
distance between the upper limit and the
lower limit. The upper limit shows at the top
left corner of the screen. The lower limit is in
the bottom left corner. For example, if the
upper limit is 40 feet and the lower limit is 70
feet, the zoom window size is 30 feet. The
word “TRACK” appears in this menu when
you first activate the zoom as shown below.
This means the X-45 is tracking the bottom in
a zoom window, always keeping it on the
display.
Press the up arrow key to decrease the zoom size, press the down arrow
key to increase the zoom size.
When the unit is switched into the zoom
