[. . . ] A flap with snap fasteners is provided at the top of the case, through which the carrying case strap can be fed. Adjusting the eyecups The eyepiece cups (1) can be easily adjusted by turning them and they lock securely into the selected positions. They can also be completely removed for thorough cleaning. For viewing with eyeglasses (Figure A) they remain in the fully screwed-in position. For viewing without eyeglasses, they are unscrewed Two positions are available for optimum adjustment (Figure B, C). If the eyepieces are very dirty, it is recommended to remove the cups for cleaning (Figure D). To do this, they are turned slightly back clockwise and gently pulled while in the fully unscrewed position. The left and right fields of view must merge and produce a single circular image. Setting the magnification The Leica Duovid offers the user a choice of two magnifications. The magnification is adjusted using the adjustable rings (2) below the two eyepiece cups. Both rings must always be completely moved into the appropriate end position. Notes: Intermediate settings are possible, although identical magnification in both optical systems cannot be guaranteed in this case. Furthermore, the automatic diopter setting (ADCTM ­ Automatic Diopter Compensation, see also the next section "Focusing/Diopter compensation") only applies in the two end positions. Incorrect settings can therefore quickly lead to a strain on the eyes and to fatigue. As the left ring is linked to the automatic diopter setting, its movement is slightly stiffer than that of the right ring. However, a slight adjustment can be required in practice. This is especially true when changing to a higher magnification after having focused with a lower magnification. The reasons for this are the larger depth of field at lower magnification, which often leads to slightly less precise focusing, and the eyes' accommodation capacity.
