the network and verify communications with the headend. The diagnostic information is
displayed on the front-panel LEDs and the On-Screen Display (OSD).
For diagnostics provided in this section:
All indicators are in decimal notation unless otherwise noted.
All signal-level and quality indicators are based on a 1% to 100% scale, unless otherwise
noted.
All sample displays are illustrative; actual data may differ from the examples.
