If you move the zoom bar all the way to the bottom of the
display, the
Bottom Track and the Bottom Lock
features can be activated.. When the Bottom Track
feature is activated, the Zoom Bar changes to a thin bar
extending from the top to the bottom of the display.
Pressing the “
ZOOM
∪ ∪
” button once more activates the
Bottom Lock feature. When in Bottom Lock, the Zoom
Bar changes to a thick vertical line extending from the top
to the bottom of this display. Move the zoom bar up to
return to the regular zoom operation and turn Bottom
Lock off. Moving the zoom bar all the way to the top of
the display turns the Zoom off and returns you to full
screen bottom history.
Fish Symbol (Turn on/off)
Pressing the soft key labeled " FISH " turns the fish
symbol on or off. When turned on, the " FISH " soft key
will be shown in reverse video and the Twinscope’s
microprocessor will scan the output of the receiver and
looks for specific patterns which it has been programmed
to recognize as fish. If it thinks it “sees” a fish, it creates
a fish symbol in place of the normal blob or arch. Press
the "
FISH " soft key to turn this feature off.
Display Scrolling Speed Adjustment
The second softkey from the right can be used to adjust
the speed of the display. The display “scrolls” the picture
from right to left and this softkey can be used to choose a
scroll speed of “
FAST, SLOW, or STOP ”. Faster
scrolling rates are generally used when you want to see
the maximum detail possible while slower speeds are used
when you want to slow the display to show the maximum
amount of bottom history.
