Fully automatic search
The fully automatic search is directly started through the selection of this menu point,
unless it has otherwise already started following the switch-on, if in the last receiving
position no picture can be evaluated (e.g. following vehicle movements or a change of
location). The satellite search is carried out in accordance with the LEM principle (Last
Elevation Memory) and begins in the angle position of the last receiving position. In
general the receivable satellite will be found relatively quickly, as often between the old
and new location no great distance exists.
If since the last location of the vehicle a long run has been completed, it is generally
advantageous in time (search time shortening), to select the “Local search”.
The satellite, for which the fully automatic search has been used, can be pre-set under
Oyster Digital Æ Configuration Æ Satellite search.
Local search
With the selection of this menu point you open a submenu for the selection of various
countries or areas. Using it the P+/P- buttons (lines) or +/- (pages) an entry can be
selected and then activated with OK.
This will arrange for the regionally differing angles of the receivable satellites. The
resultant satellite finding is then reduced in time. This search function is of special
interest; particularly if there is a long distance between your old and new locations.
If you have pre-set a satellite under Oyster Digital Æ Configuration Æ Satellite
search which now cannot be found at the selected location, the equipment automatically
selects a satellite as the search satellite, which was principally received at your location of
the time (mostly Optus C1).
You will be shown on the screen which satellite has actually been used for the search.
Following the successful finding of the satellite there will be an automatic switching to a
programme which is actually being transmitted by that satellite.
Please note that not all satellites can be received in all places. If you are not sure
whether your pre-set search satellite can really be received at your current
location, use the local search. In this case the Oyster Digital will automatically
select a receivable satellite.
Manual search
With the selection of this menu point you open a menu with your oyster which can be
manually controlled or adjusted. For this first go to a receivable programme at your
location, as otherwise you cannot receive a picture. (See Transmitter List Appendix and
Search Satellite Appendix on page 33).
With the manual search, for example, one can manually optimise the antenna position or
can control the new satellite. The menu shows the rotation and the angle in degrees
relative to your vehicle as well as the signal strength. The strongest signal presents at the
same time the best picture quality. The signal strength varies however according to the
programme and the location. To receive a picture you need 3 green indicators (DVB,
FEC and QPSK) as well as a C/N value of at least 6 or higher in the signal strength
window.
