acronyms,see“Glossary”onpage 157.
WARNING:
To avoid injury to the patient, use
only an Orbital (Orb) exam type
when performing imaging through
the eye.
Verify that the patient information,
date, and time settings are
accurate.
To avoid carrying over
measurements from the previous
patient, start a new patient
information form for each new
patient before you perform
calculations on the new patient.
See “To create a new patient
information form” on page 34.
