Agile OOB Tuner Hunting

Diagnostics

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.
