ISSUE1 5-13 Inspection
6 Verification of footswitch connection
The connection status of the footswitch can be checked by confirming the footswitch indicator is illuminated on
the touch-screen after the ultrasonic generator is turned ON. Note that, however, the displayed screen differs
depending on whether one single THUNDERBEAT or SONICBEAT is connected or both THUNDERBEAT and
SONICBEAT are connected.
Checking the illumination of footswitch indicator(s)
Confirm that the footswitch indicator connected to the ultrasonic generator is
illuminated (see Figure 5.13).

7 Verification of the high-frequency(RF bipolar)
output (when using the THUNDERBEAT)
Check the presence of output by pressing the THUNDERBEAT handswitch or the pedal on the footswitch for
THUNDERBEAT. Note that the displayed screen differs depending on whether one single THUNDERBEAT or
SONICBEAT is connected or both THUNDERBEAT and SONICBEAT are connected.
WARNING
The output should always be inspected outside the body
cavity. Otherwise, tissues may be burnt.
Verify the high-frequency (RF bipolar) energy delivery before
surgery. Otherwise, the THUNDERBEAT may not function
properly during the surgery.
For inspecting the output in SEAL mode, do not press the
SEAL & CUT button (purple) of handswitch or the SEAL &
CUT pedal (left pedal: purple) of the footswitch accidentally.
Otherwise, the gauze will be cut by the friction of the grasping
section (jaws) and the probe tip. This may result in the
grasping section wearing prematurely and/or damage to the
probe tip which could result in the tip breaking.
