The Vamo 5 is really a "People's battery carrier" Inexpensive, durable and looks good. I prefer battery carrier without optical "Schnickschnak". Since the instructions for the Akkutäger in English is, you can ask Uncle Google and because there are also in German. Note: Unfortunately, this model is often shipped in "Mean" mode. Is also called "wild boar" mode .. all depends more power to the evaporator as you want and need.
Please control after inserting the batteries the minus button (left) for 15 WITHOUT screwed evaporator - hold 18 seconds down. FALSE: Display "Output Mean"
CORRECT: Display "Output RMS" (if necessary repeat the process)
