connected computers/devices to the extra USB Hub ports on the Console side.
6. Connect the external power adapter from a wall outlet to the power connector on
the rear panel of the KVM switch.
7. Power up the first computer/device and wait for it to fully boot and test keyboard/
mouse functionality.

low-pitch beep is generated for errors and the bad key sequence will not be forwarded
to the selected computer.

followed by pressing left <CTRL> once, which will enable / disable the hotkey feature.

(Example: Selects the computer at port 1.)
Left <CTRL> + Left <CTRL> + <2>
(Example: Selects the computer at port 2.)
