Upper Jaw Support
Reference Plate Settings
Take note of the scale setting of the reference plate following adjustment. Always read the settings
on the side of the scale (see Figure 39).
Because the plates can be mounted in both directions, it is necessary to record the side of the
Upper Jaw Support (A or B) from which the scale has been read.
Always transfer the scale value and the indication letter, as well as the number of the
reference plate which was used, to the patient's folder to prevent errors in patient
positioning.
Readjusting the Reference Plate
To readjust the reference plate for subsequent fractions, use the data noted in the patient's folder
from the initial setup and adjustment.
Make sure that the correct side and position of the reference plate are used to avoid
incorrect positioning of the patient.
