OPERATION
START-UP OPERATIONS
After power is switched on, a welcome text will appear for a few seconds, indicating:
“WRAASE WRX-137” and
the firmware version number.
The display then changes to show the question
"PC control Yes / No?"
. Press the
" No"
button if you want to run the receiver in the manual mode only. If you want to allow the PC to
modify the receiver channels press
"Yes"
or just
wait
a few seconds and the PC-control mode
will be automatically loaded by default.
When
PC Control
is active, manual operation is still possible, however frequency selections by
the PC software will have priority. The
P
C
symbol in the LCD indicates that the PC control
mode is active in the background.
MODES OF OPERATION
Press the
“Mode”
button to access one of the three possible general modes:
Manual Mode, AutoScanMode and ProgScanMode
.
To confirm your selection, press the
"Yes"
button. Press the
“Mode”
button again to leave
the currently active mode and to start a new selection
Ø
Manual Mode:
The 5 fixed frequency channels can be selected one after the other by
pressing the
"Up/Yes"
button. Pressing the
"Down/No"
button activates the
manual frequency adjustment mode.
“Down/No”
and
“Up/Yes”
can then be used
to tune the receive frequency in 10 kHz steps. To leave this mode, press the
“Mode”
button.
Ø
AutoScan Mode
: In
AutoScanMode
all the 5 fixed frequency channels will be
scanned and continuously checked for a satellite signal. As soon as the receiver
detects an APT signal, it remains on that channel as long as the signal persists and
scanning will continue as soon as it disappeares. As the receiver checks for the
presence of a subcarrier, scanning will only stop on true satellite signals and cannot
be disturbed by other signals. If the scanner has stopped on an unwanted satellite
frequency, you can at any time restart scanning by pressing the
"Up/Yes"
button.
The "Down/No” button has no function in the AutoScanMode.
Ø
ProgScanMode:
The
ProgScanMode
works equally to the AutoScanMode except
that scanning only takes places over certain preselected channels: After the
ProgScanMode
is selected, all 5 available fixed frequency channels will be displayed
one after the other and you are asked to confirm them by either pressing
"Yes" or
"No".
Scanning will then start automatically after the last available channel is
confirmed with “Yes” or “No”. Your frequency selection will not be stored and has to
be renewed at any new call-up of the ProgScanMode.
