I think the Most you can find out so.
By this Machine only 1 is not Clear .
I mean what is
Intensity control, should be clear
Timer control , same
Needle Cord, also
Foot pedal ,also
Power On/off , also
Pilot an Output , i saw othe rmachiens of this i think its just lamps .
This Variable Push Button timer im not 100% Sure but i think its for ther Button (the 4) in the Middle.
I saw by Other Pictures you can pull this buttons out.
I think because its Mechanical , that you can save with timer control and timer buttons , make presettings like for 3-4-5-6 seconds treatment time.
In my childhood, my father had a very old iron that was from 1970, since you also had such options. Even if it was very complicated. Also nen very old cassette recorder from 1980, also had such options. Had endless buttons that you can no longer find today.
But i think the Timer Buttons are just like a Second Option to work without foot pedal.
i mean you can test this machine out without risc on a piece meat with hairs or the other possibilities.
by Ebay here you get a machine restaureated for 70 euro arround.
But i saw of the imperalal deluxe 3 versions… i mean the controll field is the same.
But the case was 3 times other. What is now the original , i dont know.
