Confirming extension/shrinkage, upward/downward movement and rotation of the arm
While pressing and holding the arm lock release switch, move the arm in each of the extension, shrinkage,
upward, downward and rotation directions. Check for abnormal sound and insufficient stroke. Further

Conforming the operation of the collimator
At first, make sure that the collimator is mounted correctly. Loosen the collimator rotation stopper screw,
rotate the collimator, and make sure that playback is not detected.
Next, confirm the light irradiation field. Turn the irradiation field adjusting knob to the completely open
position, press the collimator lamp switch, and make sure that the irradiation field lamp lights. After that,
turn the irradiation field adjusting knob to the completely closed position, and make sure that the light
irradiation field lamp is completely extinguished.
