How do I reconnect the Samsung Smart Control if it stops working?

If the Samsung Smart Control stops operating or works abnormally, first try replacing the batteries. If the problem persists, move to between 1 foot and 13 feet (30cm to 4m) of the TV, aim the Smart Control at the TV's remote control sensor, and press the RETURN and GUIDE buttons simultaneously for 3 seconds or more. The Connected icon will appear on screen once pairing is successful. (Page 31)
