Arctiko BBR100, Operating Instructions Manual, Page: 20 / 36

To achieve the operation:
- Open the recorder door (3).
- Lift the pointer (2) so as to release the diagram (1).
- Unscrew the knurled nut (4) and remove the diagram (1).
- Firmly hold the case in one hand and, with the other, pull the mechanism axis toward the outside
by alternatively swinging up and down to release it from its base.
- Change the battery located behind the mechanism, replace the mechanism in its case up to the
stop.
For two-speed versions, the mechanism thus taken out allows access to the speed-changing lever.
- Tighten the nut, the knurled part toward the outside, up to the stop.
To set the time, turn the milled axis clockwise by using the end of the fibre point pen as a mark. This
direction is imperative to eliminate the looseness in the clockwork mechanism.
B) Putting the fibre point pen in place
- Lift the plate´s pointer (2).
- Insert the end of the pointer into the fibre point pen´s slide rail up to the stop (6).
- Remove the cap by pulling and turning it at the same time.
- Do not place the point of the fibre point pen in contact with the fingers.
- Gently place the pointer on the diagram again.
C) Installing the diagram
- Release the pointer from the diagram (2).
- Unscrew the knurled nut (4).
- Place the diagram on the drive´s axis (1).
- Insert the diagram under tabs foreseen to hold it.
- Tighten the nut, the knurled part toward the outside, up to the stop.
- Gently bring the pointer on the diagram.
D) Use of the clockwork mechanism
Winding the clockwork spring
Turn the knurled button (4) clockwise up to the stop without forcing it.
When the spring is completely unwound, the winding takes from 8
Ω to 9 rounds. (one round per 24
hours of operation).
Replacing the diagram and setting the time
To lessen the uncertainty of time setting, the operation shall be carried out on an even hour.
