Optotype Selection

The Auto Phoroptor RS interface includes optotype selections for letters, numbers,
tumbling "Es", Landolt "Cs", and Children's Charts. The optotypes can be changed
using the scroll wheel on the Auto Phoroptor RS controller or the ClearChart 2 remote.
The Auto Phoroptor RS will accommodate either Snellen or Decimal optotype notation
and different letter sets including the 17 letter set, 8 letter set, Sloan, and HOTV by
changing the default optotype settings in the ClearChart 2 menu using the remote
(refer to Configuring the ClearChart 2 section in this manual). The selected default
letter optotype will be presented on the Auto Phoroptor RS. In addition, the Children's
charts can be changed by selecting the preferred set of charts when selecting the
Alternate optotype default setting. The Auto Phoroptor RS will display whatever
Children's charts are selected.
Optotype size can be changed using the up and down Acuity keys on the Auto
Phoroptor RS Controller, and the size buttons or up and down arrows on the
ClearChart 2 remote. Red/Green filters can also be applied using the Controller or the
remote.
