Confirming Tuning Status
To check the tuning status:
Enter service mode [Display]
+ [5] + [Vol. +] + [Power].
Press the [JUMP] button one
time to arrive at DM service
mode.
Press the [3] button seven
times to display the Front
End screen.
Key Items to check include:
Verify the In Band and OOB status are
“LOCK”.
SNR (Signal to Noise Ratio): There is no
hard value to confirm signal strength is at
an acceptable level but as a rule of thumb
a SNR of >20 is usually acceptable. SNR
of 25->30 is preferred.
Note if uncorrected errors is high it could
indicate a weak or noisy signal is being
received and the DMB is unable to
correct. There is no hard value or
threshold value.
