12 Maintenance, repair and disposal
•
It is recommended to regularly clean the front panes of the transmitter and the receiver.
•
Clean the unit with a clean, damp cloth. In particularly dusty environments we recommend to spray
the cleaned front pane with an antistatic product.
•
Do not use any aggressive or abrasion-developing cleaning agents since they could attack the
surfaces. To avoid electrostatic charging on the front, do not use any woollen cloths.
Scratches on the front panes of the optoelectronic sensors may deviate the light beams and
impair the function.
•
Only the manufacturer is allowed to repair the unit.
•
Dispose of the unit in an environmentally friendly way in accordance with the applicable national
regulations when it is no longer used.
