Prodecoder HU92 Tester Key
The tester key can only be used with Prodecoder HU92
This Tester Key is specially designed to help you determine the correct slot of the Prodecoder HU92. Rotating the tool in 180 degree brings different decoding directions.
If the Prodecoder HU92 is put into the wrong direction, the pins and the pumping will yield no result. Also the Prodecoder may be damaged.
