To check the batteries or battery tubes within an SDL, it may become necessary to remove the white SDL cap.



Figure 1: Note the white SDL cap


Carefully unscrew the white cap going counter-clockwise.

With the cap removed, batteries may be replaced. Battery tubes can be checked and o-rings can also be inspected. Whenever the cap will be reattached to the SDL, be careful not to cross-thread while tightening it back on.
