Hold down the – and + buttons together until you see the word “Pair?” or “Paired”.

If “Paired” is displayed hold down the middle button until it shows “Pair?”

Remove the cover from your transmitter by pressing the release catch on the back and sliding the cover up then hold down the button until you see red LED light. When you release the pair button the LED flashes as the transmitter pairs with the display unit. Your display should now read “Paired”.
