MAINTENANCE

Proper maintenance of the Firefield Siege monoculars is recommended to ensure longevity. It is recommended that when the 
monocular becomes dirty that it is wiped down with a dry or slightly damp cloth. Blow dirt and debris off all optics and then clean 
lenses with a lens cleaning cloth.  To remove oils or dried water spots, apply a small amount of denature alcohol to a lens cloth 
or cotton swab.  Clean the surface of the lens and let dry.  Finally use your breath to clean the lens once more. To protect the 
monocular store it in the protective padded case when not in use.  No further maintenance is required. Do not attempt to disas-
semble any components of the monocular. 

STORAGE

Cover with the objective lens and the eyepiece with the included lens covers. For long-term storage, place the monocular in a 
cool, dry and ventilated area
