Koss FIIRE REMOTE CONTROL UNIT - Manual (Page 10)

Backlighting
The RCU Mode Selection buttons are backlit. One of these buttons lights up
whenever a button is pressed on the remote to indicate which Control Mode the
remote is in; PC, TV, AUX, or CAB/SAT. If the backlighting seems dim, the batteries
may need to be replaced. There is no backlighting on any other buttons.
ON/OFF Switch
This switch turns the selected device on or off. The device is selected with the RCU
Mode Switches; PC, TV, AUX and CAB/SAT.
In the PC mode, this button issues a Go to Power Menu. On the screen you have
options for powering off the whole house or only a particular device. At this time the
system is in not powering off, it waits for another command. Another press of the
Power button will turn the Fiire system off.
If the PC is in powered off, any button pressed on the RCU may wake up the PC.

Receiver Installation
The RCU requires a USB RF transceiver be plugged into a USB port in the Fiire box
in order to access RF and gyro functions. The USB extension cable can be used to
maximize the range of the RCU by placing the USB RF transceiver away from other
electrical components. A USB RF transceiver does not need to be plugged in to use
the IR remote functions. See the diagram below.
