divided into four focus settings controlled by the
focus ring. The focus ring features three fixed
positions corresponding to (E)xtraoral, (W)ide,
and (C)lose-up settings. A fourth mode, not

The focus ring is easily adjusted without visual
assistance. The Extraoral view is the very last
setting when rotating the focus ring to the left. Use
this position as the starting point for selecting any
other setting. One click to the right is the Wide
position. Two clicks to the right is the Close-up
position and beyond that is the Macro view. It is
best to select the focus position you desire first,
then examine the patient (except in Macro view).
NOTE: Unlike the fixed focus modes, in
Macro view it's easier to position the camera
and then adjust the focus ring. Due to the high
magnification, steadying the camera is paramount
to obtaining a good image.
