Note The touching of BOTH knobs simultaneously will some- times inhibit operation of the touch-sensingsystem. The knob- touch system overrides any KEY-type command-sothat KEY commands will not transmit, if you are accidentally touching either knob
Note Which V/B knob-setis in command is unaffected by ANY KEYS-remoteor preamplifier. It depends ONLY in where the LAST V/B command came from including the effects of pream- plifier power-updiscussed earlier
