NOTICE
Damage to the Reading Window!
Reduced reading performance due to scratches or streaks on the reading window.
b
Clean the reading window only when wet.
b
Use a mild cleaning agent that does not contain powder additives. Do not use
aggressive cleaning agents, such as acetone, etc.
b
Avoid any movements that could cause scratches or abrasions on the reading win‐
dow.
NOTE
Static charge causes dust particles to adhere to the reading window. This effect can be
avoided by using an anti-static SICK plastic cleaner (part number 5600006) in combi‐
nation with the SICK lens cloth (part number 4003353).
Cleaning procedure:
CAUTION
Optical radiation: Laser class 2
The human eye is not at risk when briefly exposed to the radiation for up to 0.25 sec‐
onds. Exposure to the laser beam for longer periods of time may cause damage to the
retina. The laser radiation is harmless to human skin.
■
Do not look into the laser beam intentionally.
■
Never point the laser beam at people's eyes.
■
If it is not possible to avoid looking directly into the laser beam, e.g., during com‐
missioning and maintenance work, suitable eye protection must be worn.
■
Avoid laser beam reflections caused by reflective surfaces. Be particularly careful
during mounting and alignment work.
■
Do not open the housing. Opening the housing will not switch off the laser. Open‐
ing the housing may increase the level of risk.
■
Current national regulations regarding laser protection must be observed.
b
Switch off the device for the duration of the cleaning operation. If this is not possi‐
ble, use suitable laser protection goggles. These must absorb radiation of the devi‐
ce's wavelength effectively,
.
b
Glass lens: Remove dust from the reading window using a soft, clean brush. If nec‐
essary, also clean the reading window with a clean, damp, lint-free cloth, and a
mild anti-static lens cleaning fluid.

replaced. Contact SICK customer service to arrange this.
b
If the reading window is cracked or broken, the device must be taken out of opera‐
tion immediately and repair by SICK must be arranged immediately due to safety
reasons.
