• SNR is displayed when the DAP locks to an input program
channel and indicates the signal to noise ratio of the input signal
and is expressed in dB. The following are the desired input SNR
ranges for the appropriate signal modulation type:
• NO SIGNAL indicates that the input signal was not detected (no RF input)
• PLEASE SCAN indicates a scan was not performed or is required again
• AUDIO ONLY indicates no video signal
• NO AUDIO indicates no audio signal present
• SCRAMBLED PRG indicates the signal has encryption
• NO PROGRAM will be displayed if a valid lock is acquired but no
program signal is actually being detected
