Inspection 5-14 ISSUE1
CAUTION
Do not touch the probe tip during output. Otherwise, the
high-frequency (RF bipolar) current may cause burns.
If the output tone does not sound or the output screen is not
displayed even when the handswitch or footswitch pedal is
pressed, immediately stop using the system and turn the
system OFF. The ultrasonic generator, the THUNDERBEAT
or footswitch may be defective. Take proper measures as
instructed in Chapter 8, “Troubleshooting”. Continuing the
use of the ultrasonic generator in this condition may result in
burns of the surgeon, surgical staff and/or patient.
If the output tone does not cease to sound even when the
handswitch or footswitch pedal is pressed, immediately stop
using the system and turn the system OFF. The ultrasonic
generator, the THUNDERBEAT or footswitch may be
defective. Take proper measures as instructed in Chapter 8,
“Troubleshooting”. Continuing the use of the ultrasonic
generator in this condition may result in burns of the surgeon,
surgical staff and/or patient.
Do not touch the container with the probe or grasping section
during activation. Also, do not fully submerge the grasping
section in saline, otherwise an error window could be
displayed along with an error tone.
If an error window is displayed together with an error tone
during the inspection of the output, remove any remaining
saline from the probe tip and the grasping section with dry,
sterile gauze. Then, retry the verification submerging the tip
in saline correctly.
If you retry the verification and the window and tone persist,
stop using the system and take remedial measures by
referring to Chapter 8, “Troubleshooting” in the instruction
manual for the ultrasonic generator.

If the output level is erroneous, press the “Plus or Minus button” to set
the correct output level.
When the THUNDERBEAT and SONICBEAT are connected, press the
“THUNDERBEAT button” and then set the output level in the “Set
screen” .
