♦
Selecting the prism indication
To display the prism value, set the Prism parameter to “P-B” or “BU/D BI/O”.
When the Prism parameter is set to “Off”, the prism value is not displayed.
When marking with the prism prescription, follow the prescription.
♦
Guide
To align the target precisely, the guide (
) can be dis-
played in the alignment circle.
It is displayed when the Guide parameter is set to “On”.
The discrepancy between the guide and target
makes it easier to recognize the target position rela-
tive to the center of the alignment circle.
When the target is precisely aligned, the guide disap-
pears.
