Figure 12. Sample Display in "RF ON" State with a Device Attached
POWER CONTROL \ RF ON State for Devices.
In this mode, the user presses "RF ON/OFF" to activate and transmit RF energy to the
coagulation device. The "RF ON/OFF" LED is activated. Power is preset for the
coagulation devices. The cycle Time (e.g. 56 s) is displayed in lower right corner and
counts up to the set value.
Impedance is measured and the value displayed in the lower left (e.g. 105 Ω).
Impedance is graphed (in the right "Test" bar) against the baseline value measured at
initiation of RF. The baseline value is also displayed above the graph and in the left
"Baseline" bar.
The percent change in impedance from baseline is displayed on the right (e.g. ↓25%)
with an arrow (↑ or↓) to indicate whether the change in value was an increase or a
decrease.
During RF application, an audible tone will sound every second for a 200 millisecond
pulse.

POWER CONTROL \ RF ON with Resistivity Active, Device & Indifferent, Dispersive
Electrode Attached.
"RF ON/OFF" is transmitted to the device and the "RF ON/OFF" LED is activated.
Measured impedance is displayed (120) but not graphed.
Resistivity is measured and graphed ("Test") against the "Baseline" value (300 Ω/cm).
Percent change in resistivity is displayed on the right (e.g. ↑ 20%).
Power transmitted at 50 W.
Time (33 sec) counts up to set point.

Figure 14. RF Generator Cycle Complete, Returns to Power Control "Ready"
State
When the RF cycle is complete upon reaching preset time, generator returns to the
POWER CONTROL MODE Ready State.
"RF ON/OFF" terminates when Time equals set point, and LED turns off.
"Time Limit" message is displayed in the upper right.
Parameters display for 3 seconds, then reset to preset values.
Final Impedance is measured (80 Ω) and displayed in lower left and is graphed against
the "baseline" value (100 Ω).
Final Percent change in impedance is displayed (↓ 20%).
Final Power transmitted shown (50W).
Time at Termination of RF energy is displayed (90 s).
Figure 15. User Terminates Energy Cycle – Generator Returns to "User
Request" State
When user presses RF ON/OFF button to terminate RF transmission, generator returns to
the POWER CONTROL MODE User Request State and "RF ON/OFF" LED turns off.
"User Request" message is displayed in the upper right.
Both device and indifferent, dispersive electrode remain connected.
Parameters display for 3 seconds then reset to preset values.
Final Impedance measured (90 Ω) is displayed and graphed against baseline value
(100 Ω).
Final Percent change in impedance is displayed (e.g. ↓ 10%).
Final Power transmitted is shown on the left (50 W).
Time at User Termination of RF energy is displayed (41 s).
Figure 16. Generator Enters "Diagnostic Evaluation Mode"
To enter the Diagnostic Mode from the POWER CONTROL - Ready State, user presses
the MODE button.
RF energy is inactive and the "RF ON/OFF" LED is off.
User connects an accessory device (not yet available), presses "RF ON/OFF" to set the
baseline resistivity value.
Measured resistivity (300 Ω/cm) is displayed and graphed against baseline (250 Ω/cm).
Final Percent change in resistivity is displayed (↑ 20% indicating an increase).
