Searching for a signal with the “Search” option is used for restoring normal re-
ceiver operation if the received signal is interrupted or lost, or is changed by the
local broadcast satellite services provider.
A signal search is enabled by setting the Search option to ON, and is activated
automatically only if the carrier signal is interrupted or lost for more than 20 sec-
onds, and only if the receiver is operating in normal mode (i.e., menus are not dis-
played). If the lost carrier signal is recovered within 20 seconds, the receiver will
attempt to synchronize with the last locked channel. If unavailable, the “NO
CHANNEL” banner is displayed. If the lost carrier signal is not recovered within
this time, a signal search is activated automatically.

Once activated, the receiver begins searching for a signal associated with the cur-
rent Network ID. When a possible match is found, the search is temporarily inter-
rupted while the receiver attempts to synchronize with the found signal. If syn-
chronization is successful, the signal status is displayed on-screen. Settings can be
saved, as required, before exiting to video (current channel). If receiver synchroni-
zation cannot take place, the signal is discarded and the signal search is automati-
cally resumed. If no signal is found, the signal search continues indefinitely, and
must be manually terminated. A signal search can also be manually terminated, or
interrupted and resumed with different settings. To disable the search, set the
Search to OFF. A search is also terminated automatically if the current channel is
changed, or if the MENU button is pressed.
Signal Searches are constrained or limited by the current Search Type and the
boundary settings for the Lower and Upper Range frequencies. Default Search
Type, Lower Range and Upper Range (frequency) criteria used for conducting the
Signal Search can only be changed via the menu interface. For information about
factory default settings, see “User Setup menu”.
