Clean the vertical sealing surface of the LM500
case to ensure no debris is present that would
affect the O-ring seal.
2
Carefully unpack the lens/dial assembly.
Remove protective film from the lens. Place
the O-ring around the lens.

Installation in temperatures below 60°F may
be more difficult as cooler temperatures will
make the O-ring less pliable.

surface. Push hard from the center of the lens.
Take precautions to prevent scratching the
lens.
Note:
A small amount of lubricant may be required
(water, saliva, natural skin oil, clean engine or
compressor oil). DO NOT use P80 or any
similar type of lubricant. This will cause the
lens to crack.
