Upgrading the old manual would be possible but does not really make sense. The old manual has to be dismantled completely and re-assembled. As the parts of the manual (case, pressure sensor, pc board, position sensor) are glued together the remains of the glues (especially a double sided foam tape with excellent adhesive strenght) have to be removed carefully before the manual can be re-assembled.

Only the case and the position sensor of the old manual can be used in the new manual. The pc board and the pressure sensor have to be replaced and all parts have to be mounted together (glued and soldered). Another problem is that the glued surface of the positions sensor does not adhere anymore (or at least not very good) after it was removed from the old manual.

Because of the required working time and parts an update would be more expensive than a new manual. But if you still want to update your old manual you can get the required spare parts from us: pc board, pressure sensor and glue material (double sided self-adhesive tape to fix the pc board on the case, two small self-adhesive balance foils as the pressure sensor is narrower than the position sensor).

A manual how to assemble the new manual is available (internal technical document, so far only in German language, but with many explaining pictures).
