4.3. Quartz Clockwork
Using both hands, place fingers underneath the edge of the drum and lift it off the clockwork. After
that, the revolution cycle can be set by moving the red gear wheel to the desired position (daily,
weekly, or monthly). The highest position is 7 day (weekly), the middle position is 31 day (monthly)
and the lowest is 1 day (daily).
Warning:
After changing the drum revolution cycle you will need to insert the corre-
sponding chart paper. Standard delivery includes weekly charts, but this can be changed
at the time of purchase.
To start the electronic quartz clockwork, simply insert the provided AA battery into the battery holder.
Be sure that the positive and negative ends are in their correct positions. After the battery is in place,
put the recording drum back on the clockwork.
