Be sure to wash your hands prior to starting the examination.
Clean the headrest and chin rest with an alcohol swab before putting the patient behind the instrument. A tissue can be placed on the chin rest.
Before starting the examination of the patient you must be sure the patient is comfortably and properly positioned in front of the instrument.
Be sure the patient's chin is in the chin rest and their head is tight against the head rest with the instrument at a comfortable height for the patient. The chin rest height should be adjusted so the patient's eye level is at the eye level mark (#1) on the headrest.
