Remote Control
Three different configurations of the ClearChart 4P remote control are available to accommodate
preferences for different optotype size progressions and different notations. The type of remote
that is packaged with the ClearChart 4P depends on the catalog number of the instrument that was
ordered. The numbered buttons at the top differentiate each remote control by presenting a specific
optotype size progression and notation.
