Operation:

1. Press the button of ZW20-J for one time, and learning indicator light once, in press a button on the remote control of arbitrary, study indicating lamp glimmer four times, says learn successful, right now ZW20-J decoding the level of output feet locked state. (similar to PT2272-M4)

 2. Press the button of ZW20-J for 2 times , and at the same time learning indicator twice, in the press a button on the remote control of arbitrary, study indicating lamp glimmer four times, says learn successful, right now ZW20-J decoding output level for interlock feet state. (similar to PT2272-BMD at l1-l4)

 3. Press the button of ZW20-J for 2 times, at the same time, learning indicator light is three times, in the press a button on the remote control of arbitrary, study indicating lamp glimmer four times, says learn successful, right now ZW20-J decoding output level for the feet locked state. (similar to SC2272-T4)

 4. Press the button of ZW20-J for 2 times, at the same time, learning indicator light is four times, click on the remote control in any key, learning indicator light four flashes, say learning success, at this time ZW20-J decoding output level for the point start feet state.

 5. Hold learning button and hold it down, and at the same time learning lamp light 10 seconds long put out, says clear success, this time can loosen the learning buttons.
