Moving the Zoom Window

screen, by pressing the arrow keypad up or down. This
will move the zoom “window”.
If you prefer to keep the window in its new posi-

new window position requires different steps if you are
in Auto range when you move the window versus being
in Manual when the window is moved.

R
keypad up to view a shallower range or
down to view a deeper range. The range scale on the
left side of the zoomed picture will be highlighted.
2. When the window reaches the desired range, press
F
to accept. A ‘Change To Manual Range?’ window
will appear. Highlight ‘Yes” and press
F
.
3. If you do not want to save the range, highlight ‘No’ and
press
F
. You may then resume manually moving the
zoom window.
4. Press
Q
at any time to return to an auto range mode
display.
