Palfinger radio control: HPLS, OLP, Micro, Paltronic. What is it?

Who knows the radio control? (Please see pictures) What means: 1. HPLS 2. OLP 3. Micro speed 4. Paltronic 5. Reoil recovery Would be nice if someone has information. If you have only one Ifo, is also OK, please post here. Thanks Ralf PS: I have a crane license and I also get instruction, I can’t wait and I want to get all possible information beforehand.
