The following front-panel functions are active during the Remote mode:
• All front-panel status LEDs. This includes the LEDs on the front-panel preset
buttons, although the buttons themselves are not active.
• The Remote mode remains active whether or not controlling devices are
attached to the remote ports and whether or not commands are being received.
Note that commands from the front-panel remote port override any commands
received from the rear-panel port.
