Near Vision Rod and Card

The near vision testing accessories include a rod, reading card, and a card illuminator. The reading
card is attached to the card illuminator. Place three AAA batteries provided in the card illuminator. Slide
the card illuminator onto the near vision rod and position it at the desired reading distance. Loosen the
thumb screw on the convergence lever in the center of the Phoroptor head. Mount the near vision rod
in the convergence lever and tighten the thumb screw. The Reading Rod Holder is held in the stored
position by a spring clip. The Rod Hinge contains two pins, which engage into the clip when moved to
the vertical position. Please exercise caution when moving the Phoroptor head to make sure the rod is
not inadvertently lowered (Please refer to Figure IS-11).
The reading card automatically illuminates when the near vision rod is lowered. Reduce the illumination
level by pressing the button on the underside of the card illuminator (Please refer to figure IS-12).
The card illuminator automatically shuts off when the near vision rod is raised. The card illuminator
automatically shuts off after 15 minutes when the rod is lowered.
