7. Point the distal tip of the ber optic catheter directly at the center of the energy
detector. Ensure that the catheter is no less than one inch (2.5 cm) and no more than
two inches (5 cm) away from the front surface. The red visible beam must be in the
center of the detector when calibrating.
Warning: System faults may occur during the procedure if
the catheter is not perpendicular to and/or at the proper
distance from the detector surface duringcalibration.
8. Depress and hold the footswitch down until lasing stops. The Lasing light and red
lasing status light on the top of the control panel illuminates and the CVX-300 begins
lasing.
Note: the Power Error lamp may icker momentarily during the Calibration cycle as
the laser adjusts energy output (an audible tone will be heard when the PowerError
lamp illuminates.)
9. During the calibration, the display window shows, in the three rightmost digits, the
energy out of the ber optic catheter. As the CVX-300 calibrates, the energy out
of the distal tip of the ber optic catheter increases or decreases until the energy
corresponding to the uence setting for that ber optic catheter is reached. When the
calibration is completed, the CVX-300 stops lasing, displays the nal calibration energy
value for approximately ve seconds, then returns to the Standby mode, and the Cal
OK advisory light illuminates. When the calibration is complete, the nal calibration
energy value is visible in the display window.
10. Compare the calibration energy reading displayed with the energy range for the ber
optic catheter selected. (See catheter package for appropriate ranges.)
NOTE: If the calibration energy at the end of the calibration step was not read, or if
an energy reading is desired at any other time during the operation of the CVX-300,
check the energy out of the ber optic catheter by selecting the Ready mode, depress
the Read Energy button, aim the distal tip of the ber optic catheter at the energy
detector, and depress the footswitch. After reading the energy, depress the Standby
button to return the CVX-300 to the Standby mode. (Figure 7)
