Use and Care of Optional Lenses (cont’d)
Operation
The 25mm, 50mm and 75mm lens assemblies provide

functions. By turning the appropriate adjustment
rings, one can focus on objects, or reduce the amount
of incoming energy (25mm and 50mm lenses only).
Installation / Removal
To mount the lens assembly, orient the lens assembly
such that the alignment dot on the lens housing and
the groove on the bayonet male leg line up with the

the lens mount assembly and turn clockwise until the
lens assembly locks in place (approximately 30
o
). To
remove, press the release button on the lens mount
assembly and turn the lens assembly counterclockwise
(approximately 30
