10.2. Liability for Malfunction or Damage 

 
 
OCULUS considers itself responsible for the 
safety, reliability and functionalism of the 
unit only if the unit is used in accordance 
with this Instruction Manual. 
 
The unit contains no parts (except the light 
bulb), which require maintenance or repair 
by the user. 
No liability whatever is possible on the part 
of OCULUS if assembly work, additions to 
the unit, readjustments, maintenance work, 
alterations, or repairs are carried out on the 
unit by non-authorized persons or if the unit 
is improperly cared for or handled. 
 
If the above-mentioned work is carried out 
by authorized persons, these persons must 
be requested to provide a certification of the 
type and extent of their repair work, 
including details on changes made in the 
ratings or the capacities of the unit if 
required. The certification must bear the 
date on which the work was carried out as 
well as the name of the service company 
and must be signed. 
If desired, OCULUS will provide authorized 
persons with circuit diagrams, replacement 
parts lists, additional descriptions, and 
adjustment instructions for this purpose. 
 
Use only original parts from OCULUS for 
repairs.
