Cleaning
NOTICE
Equipment damage due to improper cleaning.
Improper cleaning may result in equipment damage.
Only use recommended cleaning agents and tools.
■
Never use sharp objects for cleaning.
■
Clean the optical surfaces at regular intervals and, in the event of contamination,
►
with a lint-free lens cloth (part number 4003353). The cleaning interval essentially
depends on the ambient conditions.
No modifications may be made to devices.
Subject to change without notice. Specified product properties and technical data are
