NOTE ­ International Operations:
Additional procedures are necessary for return of
defective parts from international service operations. Instructions have been provided to each
area of operation by the Carl Zeiss Meditec International Parts Department. If you are
unfamiliar with the required procedure for your area, or have any questions regarding the
procedure, please contact the Carl Zeiss Meditec International Parts Department.
When you receive spare parts from the Parts Department, save the packaging material for
returning the defective part for repair. Many of the parts are delicate and expensive; extra
attention to packaging will pay off in less damage to parts during shipment.

individual service engineer.
