THE DIOPTER
The BTC has a fixed, non-adjustable diopter. The diopter of
the daylight scope must be adjusted in order to focus the
BTC display.
ADJUSTING THE OBJECTIVE LENS
The Focusing Ring is located on the objective end of the BTC
and is used to fine-tune focus. Frequent focusing on objects
at different distances will ensure a crisp image.
Min. Focus Distance: BTC - 2 ft
LENS COVER
We suggest covering the Germanium lens with the provided
lens cover to protect the lens when the product is not in use.
MAGNIFICATION, ZOOM
When the screen does not display menu settings, use the
rotary knob to adjust the magnification. Magnification can
be adjusted to 1x, 2x, and 4x.
