SICK service and repair
If correct operation of the CLV cannot be restored using the troubleshooting
measures provided above, the device may be defective. The CLV does not contain
any system components that can be repaired by the user.

The CLV does not require maintenance. The self-monitoring functions enable the
device to operate fault-free at the reading station. The CLV indicates errors with the
status ST in the data output string (if enabled). If operated under extreme conditions
(excessive dust, abrasion, humidity), we recommended that you clean the reading
window at regular intervals using a mild, water-soluble detergent to maintain the
reading performance.
13. Maintenance
When cleaning the reading window, avoid any scratching or scouring movements
on the surface of the glass.
If necessary, also clean the LEDs.
