Tresco Radar Overlay - Operator’s manual
Page 17
In Information Mode, the user can select which layers will be shown on the chart
when the “CHART USER” density is selected.
CHART BRIGHTNESS
Select the opacity of the chart by means of the slider.
When the slider is more to the left, the impact of the chart image will be minimum.
When the slider is moved to the right, the chart becomes more apparent
RADAR BRIGHTNESS
Selects the color intensity of the radar echoes by means of the slider.
When the slider is more to the left, radar-echoes become darker (more contrast
against the electronic chart). When the slider is moved to the right, the echoes
become brighter.
Remark: experiment with different settings of chart brightness and echo visibility.
Choose a contrast that satisfies with the current lighting conditions (day, dusk or
night).
TRIP
On the top row, the tripmeter displays (from left to right): distance, time and
average speed of the tripmeter. The bottom rows shows (also from left to right):
PAUSE, RESET, actual speed.
Click PAUSE to pause/unpause the tripmeter, or RESET to reset the tripmeter.
Click one of the values (distance, time, average speed, actual speed) to display the
corresponding value in the tripmeter in the radar screen itself.
WATERWAY
This box shows the waterway name and the km-position on that waterway
corresponding to the current position.
TO INFORMATION MODE
This option allows the user to switch to Information mode or configuration mode.
In information mode, no radar echoes are shown. A different range or region
(planning mode) can be shown North- or Course-up. To return to Navigation Mode,
select “Navigation Mode” at the top-left position in Tresco’s Information mode
screen.
This selection has to be confirmed with “YES” or “NO”. So, two user actions are
necessary to exit navigation mode.
EXIT
This option shuts down the Tresco Radar Overlay application and returns to the
start-up screen. This selection has to be confirmed with “YES” or “NO”. So, two
user actions are necessary to exit navigation mode.
