Perform Ear Rod Alignment
The ear rods are properly aligned when the ear
rings appear concentric (one centered within the
other) on the processed cephalometric fi lm. The
inside ring is the one closest to the fi lm cassette.
Vertical Alignment
1. With a level on the underside of the overhead
chassis, verify the machine is level in all
directions.
2. With a level on top of the cephalometric arm,
verify the arm is level.
3. With a level on top of the cephalostat head
positioner, verify the head positioner is level in
all directions.
4. Power the machine on.
5. Using the function switch on the control panel,
select CEPHALOMETRIC 0.4.
6. Using the kVp setting knob on the control
panel, set the kVp meter to 70 kVp on the
CEPHALOMETRIC scale.
7. Slide the lever in the collimator assembly on
the front of the tubehead to the LATERAL
position.
NOTE: If the collimator is NOT fi rmly seated in its
locking notch:
a. the alignment laser will not fi re
b. when the exposure switch is depressed,
the machine will beep rapidly, but no
radiation will be emitted
8. Remove the locking pin in the top of the
cephalostat head positioner and rotate the ear
rods to approximately 45°. This will allow the
laser alignment beam to strike the cassette.
