I am quoting Helsingin Sanomat, Kari Lehtola, Lt. Commander Mikko Montonen and the guys on the Turma who tested one of them. They all said they were fully charged batterywise but untuned and not switched on.
Here is a translation of the article here:
HS 28.1.1995 google translate
The original Finnish version is here, if anyone wants to compare the language
In which, it is crystal clear, the word 'tuned' refers to switching them on. Why are you doing this?
