11.4. Changing the Window

Sometimes extremely harsh environments can cause damage to the window.
A replacement protective front window (E-PW) is available.
To replace the sensor's protective front window, complete the following:
1. With a very small flat-bladed screw driver (e.g., a jeweler's screwdriver), pry out the
rubberized Buna-N 70 durometer O-ring. The O-ring is set in a groove in front of the
window.
2. Turn the sensor face down (window pointing down), and the window should fall out.
3. Turn the sensor face up and insert the new window. (Make sure both sides of the
window are clean.)
4. Replace the O-ring.
Warning
If you use a fine-bladed knife to remove the O-ring, be careful not to cut or
sever the ring.
Warning
Do not use any ammonia or any cleaners containing ammonia to clean the
lens. This may result in permanent damage to the lens' surface!
