NOTE: This is the 27.455MHz version! There exists also a 27.145MHz version that was the standard in Belgium and was used incidentally in the Netherlands prior to 1999. After '99, everything became 27.455MHz You can only tell the difference by looking at the crystal printed board. ELSEMA 6863.5 = 27.455MHz HY-Q 05-09 6M786 = 27.145MHz
Programming your remote: Set the DIP-switches in your new remote equal to the settings in your old remote. Don't have an old remote? Set the switches equal to the settings in the receiver instead.
