Adjusting the Scan Sector
The Dashboard operator can alter the size of the scan sector, the dark blue area across
which the antenna sweeps when auto-searching.
A wider scan sector may be required in order to find a remote station. Once the stations are
locked and if its bearing is not expected to change much, a narrower scan sector may be
required in order to quickly re-establish the lock should it be interrupted.
To Adjust the Scan Sector:
1. Ensure that the Dashboard is In Command mode (if not, click on the Guidance button
then Take Command).
In Command mode there are handles along each radial edge of the scan sector.
2. Click one of the scan sector handles on the BEV and, holding down the left mouse
button, drag to the required position. Alternatively – on a touchscreen – touch and drag.
As the handle is moved, its current position (in degrees clockwise from the vessel bow) is
displayed in blue numerals outside the perimeter of the circle.
This will cause the Apply and Cancel buttons to appear at the foot of the side bar.
3. If required, drag the second handle in the same way.
4. Click on the Apply (tick) button to confirm.
Note that the scan sector cannot be narrower than 5°, nor can it extend into the dark grey
area of the BEV (defined by the End Limits - see Artemis Mk6 Installer’s Guide).
