Placing the baand is very easy, as the baand, after being attached to the winding coil,
merely is put in a slid. The rewinding takes place in the course of approx. 30 sec. without
rearrangement of the gang and without wear of the head of the head. Spooling can take
place at a rate of approx. 5 times normal flow rate by
pulling the strip off the slit. The tone head is vertically adjusted, ensuring that the recordings
are reproduced completely correctly, even if they are played on a different device than
that used for the recordings. All mechanical functions are operated with a single
button and the work is provided with a Minus scale, which shows, on the one hand, how many minutes
are recorded and how many minutes are left. The amplifier used,
