TV volume down & OK on remote only does a basic IC self check. It does NOT clear any unit
settings.
It does not clear channel programmed settings, picture settings, channel labels, LOCK mode
settings, or password.
Using this method, it shows the unit firmware version (Peaks 1.050 and GenX 1.00) and it checks
IC communications ONLY.
This is more useful to identify the firmware version without having to decode the info in the setup
menu About/Version screen.
