4. Press the FREQUENCY button and verify that 1 MHz and 3 MHz LEOs are
illuminated. Leave 1 MHz selected.
5. Press DUTY CYCLE until Continuous is illuminated, noting that each LED is
functioning. Use the INTENSITY up button to set the output to 2.0W/cm 2 .
The fan should begin running. Press START. By applying a small amount of
water to the transducer, verify that there is ultrasound output.
6. Observe that the treatment time counts down on the LEOs. Press PAUSE.
The output should stop, the fan should stop and the treatment timer should
stop counting down. Press START and the output should resume. Press
STOP and verify that the output stops, the treatment timer is reset back to the
default, the output display is reset back to 0.0 and the fan stops.
7. Use the TIME up button to verify that the treatment time will not go above 15
minutes. Use the DOWN button to set the time back to 1 minute. Select
10% Duty Cycle using the DUTY CYCLE button, increase the intensity to
maximum and press START. While the unit is running, press the DISPLAY
button and verify that the displayed power changes from 2.0 W/cm 2 to 10.0
Watts (assuming a Scm applicator is attached). Allow the unit to run until
treatment time runs out. Two beeps should be heard followed by another two
beeps and then the display will clear back to the default.
8. Testing complete.

Calibration Procedure
1. Put unit into calibration mode. Turn the unit ON while holding down the Intensity UP
button. It is not necessary to hold the button down after the initial beep sound.
2. The Min/Sec display should read CALO indicating that the machine is in calibration
mode and at the first calibration step.
3. Place the applicator into the Ultrasound power meter.
4. Select the calibration frequency using the FREQUENCY button (1MHz or 3MHz).
5. Set the Head Size using the DUTY CYCLE button.
10% 1em applicator
20% 2cm applicator
50% = Scm applicator
Continuous = 1Ocm applicator

6. Once Applicator size and Frequency are chosen, push the START button. This will
begin the scan and calibration. The zero in CALO will flash while the scan is in
progress. Do not disturb the machine while it is scanning.
7. When the scan is complete the display will change to CAL 1.

8. Re-zero the Ultrasound power meter.
9. Using the Intensity UP button, increase the output until the power meter reads 4
{four) watts.
10. Push the START button. The unit will hold the settings in memory. The display will
change to CAL2.
11. if you are satisfied with the caiibration, push START.
12. The unit will beep to indicate that the new calibration values have been stored in
the applicator.
13. The display will change to CALO and is now ready for the next calibration.
14. After both frequencies have been calibrated and before removing the applicator
head from the power meter, check the accuracy of the power calibration. Cycle the
power to the unit off and then back on. Select continuous duty cycle and increase the
output to the settings listed. Verify that the power indicated on the UPM-DT-10 power
meter is within the indicated range. Check power at both 1 MHz and 3.3 Mhz.
