Agile OOB Tuner Hunting

Manually select an OOB frequency 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., it is not possible to press the Menu button on the OOB status screen and display MAN FREQ when the set-top is hunting.

Summary of Manual Selection of the OOB Frequency

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 Front Panel displays the frequency of the last known carrier. 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 appear on the Front Panel and on the MAN FREQ line of the OSD. When the last known frequency is selected, a dot appears 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 lasts up to 40 seconds. As the DCX3510-M searches, the frequency being searched for flashes on the Front Panel. On the OSD, the MAN FREQ line of text is cleared, the HUNT MODE displays FIX to indicate a search on a fixed frequency, and the OOB FREQ field changes to the frequency being searched for.
