1 Safety Guidelines
Please read the machine operating manual (BDA)
thoroughly.
Please note that the machine is hooked-up to an electrical
power outlet with the same voltage as indicated on the
machine identification plate and is grounded according to
the local requirements. The ground prong on the plug must
never be cut or bent in such a way that the machine cannot
be electrically grounded.
The electrical wiring of the maschine must not be tampered
with. Any change may impair the built-in-protection features.
Before cleaning and maintenance, switch the machine OFF.
Never switch the maschine ON while it is being serviced or
cleaned.
It must be recognised that certain operator errors may be
the result of medication influencing vision and ability quickly.
Always observe the safety rules of your place or lab.
For increased protection against electrical shock a special
safety breaker is recommended.
This machine is only suited for the processing of frames,
formers, lenses and demo.
Other objects or tools must never be ground with this
machine.

3.4 Optical principle
Abb. 4
The user is looking through a partly
transparent mirror 2 on a LCD that is
illuminated from the back and tha shows
the decentration values and graphics.
The lens is displayed in actual shape (not
reversed) via mirror 1 and 2. The
decentration point for blocking needs to
be in the following position: distance b
from mirror 2 (measured by mirror 1)
which equals the distance a from mirror 2
to the display. To achieve this one has to
lower or lift the lens. This procedure will
happen automatically when the
<BLOCK> key is pressed.
This imaging of the lens on the display
avoids image shifts or systematical
blocking errors since the distance
between the image and the display
equals zero.
This means that the system is parallax
free i.e. the relation of a point on the lens
with that of a point on the display remains
unchanged regardless the position of the
observer.This is particulary inportant with
prismatic corrections since it is the only
way to transfer the correct refraction
values to the final eye glasses.
