Field Description 
EMM PID 
Displays the packet identifier (PID) stream the DCH3416 tunes to for EMM data, in 
hexadecimal 
Network 
PID 
Displays the network PID to which the DCH3416 is tuned to receive network 
messages, in hexadecimal 
Hunt Mode 
The hunt mode includes Hunted, None, Round Robin (RR), Search (SRCH), Fixed 
Frequency (FIX), or EMM Provider ID (EMM). 
LKC 
The last known carrier is the last valid OOB frequency displayed in MHz and ranges 
from 70 to 130 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. 
LKC will remain blank during hunting if a valid carrier has not been found, and will be 
populated once a valid OOB is found. 
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. pressing Menu button on OOB status screen to display 
MAN FREQ is not available when the set-top is hunting. 
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.
