Maintenance and repair

Maintenance
The devices are maintenance-free. Cleaning is usually not necessary.
If the protective lens barrel becomes dirty, we recommend that you clean it professionally in
order to achieve a consistent reading performance.
Repair
For repairs, send the optical reader to Siemens without its protective lens barrel, lighting unit,
and other accessories. The current contact details are available via the Siemens Industry
Online Support.
