First make sure the receiver is plugged into the computer. Second make sure you have fresh batteries in the keyboard and they are installed in the correct orientation. Then try the following:

1. Press the Connect button on the receiver. The receiver's LEDs will go into a sequential flashing to indicate that the receiver is ready to accept a connection.

2. Press the Connect button on the bottom of the keyboard. The receiver's LEDs will now stop flashing sequentially. Then all the LEDs go off briefly, then they will all flash once before returning to the state it was in before the connect button was pressed.

3. Your keyboard should now be connected to the receiver.

They should have an on/off switch on the underside that you can use to switch on/off...

Normal 0 Press the Receiver button (and the lights will start flashing.
Then if the Keyboard isn't working, press the small RESET/CONNECT button on the back of the board to connect the keyboard to the receiver.

If the MOUSE isn’t working, push the small RESET/CONNECT button on the back of the mouse to connect to the receiver. Then they should work okay.
Hope this helps. Bud
