There is an instruction in the manual how you could do the programming/setting of the et points:
To enter the “Programming” menu, press the “SET” key for more than 5 seconds. If specified, the access PASSWORD will be requested, (parameter “PA1”), and the label of the first folder will follow. To scroll through the other folders, use the “UP” and “DOWN” keys. To enter the folder, press “SET”. The label of the first visible parameter appears. To scroll through the other parameters, use the “UP” and “DOWN” keys. To change the parameter, press and release “SET” then set the desired value with the “UP” and “DOWN” keys, and confirm with the “SET” key, to move to the next parameter.
Here, if you have other question, this might help..
