Press "Freeze Audio" push button to lock audio to a specific channel.
The LED will indicate this option has been activated and to which
channel the Audio is locked to at the moment. This means that
switching channels would leave Audio active on current channel.
Restore-Factory-Default will release "Freeze Audio" function from
any channel it is locked to.
Keyboard Status Indication
In order to enhance usability, product provides keyboard status
indications via dedicated LEDs located on product front panel. To
maintain the required unidirectional connectivity between keyboard
and product, these indication are not given on the keyboard itself as
done with non-secure products
The keyboard status indications are given via 3 LEDs on the front
panel of the product:
• CL – CAPS Lock
• SL – SCROLL Lock
• NL – NUM Lock
The indications behave the same as the LEDs on the keyboard as if it
was connected directly to computer.
Switching from channel to channel may change the status of the
LEDs based on the current settings on the computer connected to
the active channel.
