INPUT CH PLAN:
The CHANNEL PLAN mode allows the user to the select the appro-
priate frequency mode. This setting alerts the user to the appropriate
center frequency plan the DAP will use during the scan process.
• The BROADCAST option must be selected for off-air 8VSB
reception, this is automatically set if the DEMOD MODE is set to
8VSB. Reception is limited to VHF & UHF center frequencies.
• The STANDARD CATV mode is capable of locking to QAM Annex
B and 8VSB signals. This channel plan is automatically set when
the QAM B mode is selected in the DEMOD MODE command
menu. Reception is limited to CATV center frequencies.
o It is only required to choose the HRC or IRC option when these
frequency off-sets are used with the CATV plan.
SCAN MENU:
The SCAN MENU command allows the DAP unit to auto search for
available programming. It is required to perform a scan in order to
function properly.
• YES – The YES command performs a scan of the incoming
available signals by the DAP unit
• STATUS – The STATUS command displays the channels found
during the scan process
• STOP SCAN – The STOP SCAN command permits an operator to
stop an in-process scan. It is important to note that
once a scan starts the previously found channel
data is immediately erased. If the scan is stopped,
only the completed scan channel data will be
available for selection
• EXIT – The EXIT command exits the SCAN MENU without making
any modifications
The unit will display the SCAN IN PROCESS message
during the scan process if interaction is attempted.
