Agile OOB Tuner Hunting
An OOB frequency can be selected manually by pressing the
MENU
button while in the
OOB Status diagnostics screen. To exit this mode, press the
MENU
button a second time,
or press the
POWER
button.
If the set-top is in the process of hunting for an OOB frequency, control of frequency
selection is suspended, i.e. when the set-top is hunting, the ability to press the Menu
button on the OOB status screen to display MAN FREQ is not available.
Summary of Manual Selection of the OOB Frequency (OSD Frequency Override in Hunted
Mode)
The manual override frequency capability is only displayed if the box is not currently
hunting and the operator presses the
MENU
key while OOB OSD diagnostics are
displayed. The MAN Freq displays the LKC and allows the operator to select (via scroll
up/down) a specific frequency to check if a valid OOB is on that specific frequency. The
MAN Freq parameter is the OOB frequency selected in the frequency selection mode
and displayed in MHz, with the specific values of 75.25, 104.20, 72.75, 92.25, 98.25,
107.25, 107.40, 110.25, 116.25, and 103.75.
1.
When in the OOB Receiver Status Diagnostic, press the
MENU
button to enter the
frequency selection mode. The frequency of the last known carrier is displayed on
the Front Panel. The OSD displays a new “MAN FREQ” line at the bottom of the
screen, which indicates the last known carrier frequency. At this point, if desired, the
frequency change mode can be exited by pressing the
MENU
key a second time.
2.
Use the
UP/
DOWN channel or cursor keys to scroll through all 10 frequencies until
the desired new OOB frequency is found. The new frequency selections will appear
on the Front Panel and on the “MAN FREQ” line of the OSD. When the last known
frequency is selected, a DOT will appear in the middle-upper part of the Front Panel.
3.
When the desired new frequency has been selected, press the
SELECT
key to start
the search. The manual frequency search will last up to 40 seconds. As the set-top
searches, the frequency being searched for will flash on the front panel. On the
OSD, the “MAN FREQ” line of text will be cleared, the “HUNT MODE” will display
“FIX” to indicate a search on a fixed frequency, and the “OOB FREQ” field will
change to the frequency being searched for.
4.
If the frequency is found with the proper EMM Provider ID, then the front panel will
display the normal OOB receiver status. The OSD “LKC” field will change to display
the new frequency.
5.
If after 40 seconds the frequency search is not successful, the product will perform a
warm reset.
6.
TO ABORT A Search without waiting the 40 seconds, the
POWER
key can be pressed
to cause an immediate warm reset.
Note:
The front panel will display “hunt” after a cold reset from the front panel. This
indicates that the product is in a Round Robin Hunt Mode. The message “hunt” will
continue to be displayed until the proper stream is detected.
