Automatic satellite changeover
Your Oyster Digital is in a position, to automatically switch at all your locations between
the receivable satellites, without you having to be particularly involved.
For each programme position stored in the transmitter list is also stored the satellite,
which transmits these programmes (see Transmitter list appendix, page 33). If the
Oyster Digital recognises a satellite change while following a programme change carried
out by you, the antenna immediately searches for the satellite and aligns itself exactly on
the signal. You will see during this time in the status indication the report “Antenna
rotating”.
If the selected programme cannot be found on the new satellite (e.g. because at the time
it is not transmitting or it is to be found outside the receiving area), the antenna returns
to the satellite, from which the search started and switches on a programme of that
satellite.
The time which your equipment needs to carry out this change is strongly dependent, on
how far the two satellite positions are apart from each other. A change between Optus
C1 and Optus B3 can e.g. take place in less than three seconds, if the satellite positions
are known. Should the exact positions not be known, the change lasts a little longer.
This function can be broken off during the travel to a new satellite or during the search
for a new satellite at any time with the SWAP button.
So that this function can be correctly carried out, there must be a switching to “Active”
under Oyster Digital Æ Configuration Æ Automatic satellite change. In order to
use the manual search there must be a prior switching to the function “Automatic
satellite change” in the Configuration menu and “Off”, as the equipment otherwise will
always automatically return to a known satellite in order to be able to receive a picture.
