13.4 Window Exchange
Sometimes extremely harsh environments can cause damage to the front window. A replacement front window
(E-PW) is available.
For a replacement complete the following:
1. Pry out the rubberized O-ring (type Buna-N 70 durometer) with a very small flat-bladed screw driver (e.g.,
a jeweler’s screwdriver). 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.
Note
If you use a fine-bladed knife to remove the O-ring, be careful not to cut or sever the ring!
