Using your Tresco Radar Overlay
Whit the radar turned on and the PC off, the user should see his normal radar
picture.
At that moment please s itch your radar as usually to the required distance
RANGE and adjust TUNE and GAIN to the optimal value. Please set STC and FTC to
zero, unless there is any clutter generated by aves or rain, than adjust carefully
to the minimum required value.
After turning on the Tresco PC, one should see the radar picture ith underlaid
chart. A PC mouse pointer becomes visible on the screen. The chart ill appear
only if position and heading data are available and of a good quality.
All operations regarding radar can be done continuously in the usual ay by using
the radars operating panel (radar keyboard and trackball).
To operate the additional chart functions, please move the mouse pointer to the
bottom of the radar-overlay screen, and, the Tresco chart menu ill pop-up:

User Instructions
For the general instructions, commands, features and options that can be used or
selected in information mode , please consult the “Tresco Navigis River Installation
and Operation” manual.
Additionally, in the pop-up menu, the follo ing user commands can be selected:
AIS OFF, AIS ON or AIS LABELS
S itch to select if other vessels hich are equipped ith an AIS-transponder, are
made visible on the chart. Ho exactly the AIS-targets are sho n, is selected in
the system setup configuration option in information mode. An octogon symbol
indicates a vessel ith no transmitted heading information. When heading
information is received over AIS, the octagon s itches to a triangle symbol. The
direction of the triangle indicates the vessels’ heading or bearing of the target and
the fine, dashed line hich originates from the triangle, indicates the course-over-
ground. Note that the course and the heading may differ significantly depending
on actual sailing conditions (current, ind, actual rate-of-turn, …).
If the current display range allo s an AIS vessel to be dra n on scale, you ill see
the vessel outline hen this data is received over AIS.
S itch to ‘AIS LABELS’ to select hether the other vessels should be labeled by its
AIS-transmitted name. Optionally the name can be accompanied by a vessel
number, a course and a speed indication.
Remark: the more information is put in a label, the larger the label is projected on
the screen. In a place (e.g. harbour) here a lot of vessels are transmitting there
AIS-info, screen-cluttering may occur. For this reason the AIS-labels are
automatically s itched off after ten seconds. AIS-targets are still visible by their
octagon or triangular symbol.
Note: AIS-targets can only be sho n if you have connected an AIS-receiver or AIS-
transponder to the PC used for navigation purposes. (The connection is made by a
serial NMEA 183 data-cable bet een the AIS hard are and the Tresco PC.)
CHART OFF, CHART MIN, CHART USER or CHART ALL
Select hether you ant to see an electronic vector chart(S57 standard) or not.
If the quality of the position sensors and the heading sensors are OK, the chart ill
be dra n if the user has selected ‘CHART MIN’, ‘CHART USER’ or ‘CHART ALL’.
When you select CHART OFF, the chart image ill disappear. ( If ‘AIS ON’ or ‘AIS
LABELS’ is selected, targets ill still be sho n.) In this case the screen ill be very
similar to the image as it is sho n on the normal master radar-screen.
The density of displayed information of the Inland ECDIS chart is chosen by
selecting one of the follo ing interface buttons:
“CHART MIN” : minimum required navigational info
“CHART USER” : user selectable info bet een minimum and maximum density,
and,
“CHART ALL” : sho all chart data available in the S57 SENC.

Tresco Radar Overlay - Operator’s manual
Page 17
In Information Mode, the user can select hich layers ill be sho n on the chart
hen 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 ill 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 ith different settings of chart brightness and echo visibility.
Choose a contrast that satisfies ith the current lighting conditions (day, dusk or
night).
TRIP
On the top ro , the tripmeter displays (from left to right): distance, time and
average speed of the tripmeter. The bottom ro s sho s (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 sho s the ater ay name and the km-position on that ater ay
corresponding to the current position.
TO INFORMATION MODE
This option allo s the user to s itch to Information mode or configuration mode.
In information mode, no radar echoes are sho n. A different range or region
(planning mode) can be sho n 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 ith “YES” or “NO”. So, t o user actions are
necessary to exit navigation mode.
