Cleaning
9.2.1
Cleaning the device
At regular intervals (e.g. weekly), check the reading window and the housing of the
device for accumulated dirt. This is especially relevant in harsh operating environments
(dust, abrasion, damp, fingerprints, etc.). The reading window lens must be kept clean
and dry for reading.
This action, along with any cleaning, ensures full optical reading performance of the
device, and allows it to adequately dissipate heat resulting from internal power loss.
