PANORAMIC X-RAY BEAM ADJUSTMENT
Technical Manual
NOTE Always use the plus (+) key for the final adjustment. This makes sure that the slot
mechanism is correctly positioned by taking up the play between the draw nut and the
positioning thread.
For example, if you are adjusting the beam to the left by pressing the minus (-) key you should
move the slot mechanism a little further to the left than necessary, and then press the plus (+)
key to move it back to the right to the correct position.
Figure 10
If you cannot adjust the beam far enough to the left using the method described above you
may have to move the metal tab on the draw nut. Loosen the securing screw rotate the tab
slightly and then tighten the screw. The slot position should then be rechecked.
Figure 11
Press the clock key to store the slot position in the memory and move on to the next slot. The
number of the next slot will appear on the main display and start to flash.
Repeat the alignment procedure described above for this slot and any other slots.
Exit the primary slot calibration mode and check the position of all the beams again. Realign if
necessary.
Exit the service mode.
