Forward View (Full Screen)
While in the
Control Center
press the far left button until
the sideways arrow is shown in reverse video as shown at
left. This will select a full screen horizontal forward
looking display. At the top right of the screen the current
depth beneath the boat is shown in digital numbers. If the
optional speed/temperature transducer is connected to the
unit, the boat’s speed is displayed just to the left of the
digital depth as shown on the picture above.
The vertical scale at the far left of the display shows the
forward range at the center of the display. In this example,
the outer range ring is 360 feet. A target 1/2 this distance
forward would be located at 180 feet in front of the boat.
The numbers on the outer range ring indicate the bearing
from the bow of the boat. The display will show targets up
to +/- 45 degrees ahead of the boat.
Press the
GO
button to bring up additional adjustments and
features for this forward looking view. Your display menus
should appear as on the left.
Range Adjustment
Press the button labeled "
RANGE
" to bring up the Forward
Range Adjustment soft key menu as shown at left. Press
the button labeled "
AUTO
" if you would like the
Twinscope’s
internal microprocessor to automatically
select and adjust the range as bottom conditions change.
To manually adjust the range press either the range button
labeled "
∩
" or "
∪
", or rotate the large knob. If you make a
manual depth adjustment, the
AUTO
range mode is turned
off and will remain off until the button labeled
AUTO
is
again selected. Note: when in the
AUTO
mode, the soft
key labeled
AUTO
will be shown in reverse video (white
on black). To return to the main forward looking menu,
press the left soft key labeled "
LAST
".
Sensitivity Adjustment
Press the soft key labeled "
SENS
" (for sensitivity) to bring
up the choices available for adjusting the
Twinscope's
receiver sensitivity. Press the button labeled "
AUTO
" so
that the word
AUTO
is shown in reverse video (white
letters on a black background) if you would like the
Twinscope
to automatically adjust its sensitivity for
