(2) Angle the table to -90 degrees Trendelenburg and angle the collimator to
-90 degrees beam-right (Light-emitting diode-5 ON). Slowly tilt the table 20 degrees down
from the maximum-Trendelenburg position. Light-emitting diode-6 should be ON and
remain ON until the table is angled down to -79 degrees. (Light-emitting diode-5 will
also be "ON").
(3) The tilt monitors must meet the above requirements. If the tilt monitors
do not pass each requirement listed, take the following corrective actions.
(4) If a tilting table is installed as part of the system, it is necessary to mount
the table-tilt monitor to transfer angular-position information to the collimator. Proper
orientation of the monitor is shown in figure 1-7. Remove the jumper between TS2-5
and TS2-10. Connect the table-tilt monitor as shown in figure 1-8.
