The SDA will automatically attempt to lock-on to the QAM signal of the
designated channel (or frequency). Lock errors may result from a variety of
conditions, including improper unit configuration or cable connection.
Connect the cable to the digital port on the unit before using any of the four
digital modes.
If initially unsuccessful, the following error message will appear:
ERROR Signal Unlocked! Confirm Connection to Dig Port. Retry.
Press this soft key to retry to lock onto the QAM signal. This key
will appear in the lower right corner of the screen when lock
errors occur, otherwise the key will remain blank.
