7.3 Focusing of finder type
Focus a measuring object by turning the objective lens tube by its distance indication plate and the
distance marker.
When an objective lens tube does not turn around, you should confirm a screw for objective lens tube,
and please turn it after having loosened it when it closes.
Make sure that the measuring area should be larger than the targeting mark (Recommended area: For the
distance factor of 200 - More than 1.5 times the targeting mark), and then fix the objective lens tube by
screwing the attached screw (with a hexagon hole) into the fixing screw hole of the objective lens tube.
