Hi. I had a Humax 5400 set on a motor. Now I've got a DM500 and I've been trying to set it up to the motor but no luck. I think that my problem is that I have not reset the motor and it still has the settings of my Humax. Usually motors have a smalll hole where to insert a rod to be able to reset but this motor does not have anything like that. It is a bigsat motor bs100 with 2 buttons, one for east and one for west. That's all it has. Does anyone have any ideas on how to reset the motor please. Thanks.
