After putting in place the batteries into the device and inserted a DVD moistened (visualization of the manual on the internet as essential deplorable record) who needed a good thorough cleaning, I pressed the button Starting-up: nothing, no movement !!! removing the DVD that is well marked by this first experience. To empty the engine running. Try setting up a 9V DC power supply in the intended sheet: Can not detail the correct diameter. I'll try to change the batteries when I'm fit, but for now it is not worth a drink of cider! I feel that the return is not far! Well, I tried using rechargeable batteries, it worked, but I feel winded. That's better. After investigation on batteries, those that were delivered me had a date for preferential use to August 2014, when I received this product in January 2015!
