Danger All internal adjustments as well as repair work on this product must be per-
formed by expert technicians!
Replacing the Supply Unit
The primary fuse is located within the power supply module and cannot be
changed. In case of failure, the complete power supply unit must be replaced.
Please ask your nearest Studer representative.
Cleaning Do not use any liquids to clean the exterior of the unit. A soft, dry cloth or
brush will usually do.
For cleaning display windows, most of the commercially available window
or computer/TV screen cleaners are suited. Use only a slightly damp (never
wet) cloth. Never use any solvent!
