"It'll record everything a nearby alethiometer 'says' - it operates by touch, and organizes everything into numbers at the top for which separate thing it's saying. When it starts getting lots of recordings, to where it's filled up, rub the numbers at the top and they'll fade out to the next set. If you touch one of the numbers it has recorded, it'll look at that one in more detail, and list the symbols said below it, in order and with the number of times it was chosen. From there, you touch the symbol you want the translations for and it'll offer them. Touch another symbol and it'll switch it out," he explains.
