ADJUSTING THE EYECUP

Prior to using the Siege monoculars, it is best to adjust the twist up eyecup to 
your preference.  The twist-up eyecups allow you to properly observe the full 
field of view of the image without any vignette effect or darkened edges.  Even 
if you wear eyeglasses you can use the Siege monoculars effectively.  If you 
wear glasses, keep the eyecup in the down position.  Twist the eyecup to the 
up position if you do not wear glasses.  To twist the eye cups:
1.  Rotate the eye cup (2) counter-clockwise to raise the eyecup.
2.  Rotate the eye cup clockwise to lower the eyecup.  

MOUNTING THE TRIPOD

All Firefield Siege monoculars include a tripod that attaches to the built-in tripod mount.  The built-in tripod mount also works with 
most aftermarket tripods and window mounts.  The built-in tripod mount can be used with any tripod or window mount that uses a 
standard 1/4-20 UNC tripod screw.  To mount the tripod:
1.  Align the tripod’s mounting screw with the socket on the bottom of the tripod mount (4). 
2.  Screw the tripod’s mounting screw so that the tripod and the tripod mount are completely connected and firmly secured.
