What is the special condition to watch out for with the following message: Red LED blinking 2 sec
interval – Digital Demodulator does not respond?
Error code 003 (digital demodulator does not respond) requires source to be selected as "antenna" before the test is valid. If
source is not antenna, it will always give you error code 003 because digital demodulator is not turned on until "antenna" source
is selected.
