power can be increased and decreased. (Note: Set power as low as possible

for intended purposes.)

6. “DELIVERED POWER (W)” Display. Displays the actual power being delivered

in whole units of Watts.

7. “TIMER (min)” Display. Displays the time to a resolution of 0.1 minutes. This

display, prior to the start of the RF energy, shows the time set for RF energy

delivery at the target temperature. Once the RF energy starts, the display shows

the remaining time of RF energy delivery at the set temperature. If the Device

temperature is not maintained at the target temperature, the timer stops. The

timer resumes counting down once the target temperature is reached again.

During the cool down cycle this display counts up 0.5 minute to indicate the

duration of this cycle. Timer display is blank during track ablation.

7. “TIMER (min)” Buttons. Pressing the arrow buttons, sets the time the RF energy

will be on while at the target temperature. When this time has counted down to

zero, the RF energy delivery ceases. The timer can be increased and

decreased.

8. “RF TIME (min)” Display. Displays the total time the RF power has been on to a

resolution of 0.1 minutes. This display resets to zero at the onset of a new RF

energy delivery cycle. A RF energy delivery cycle is considered to be complete if

in the previous cycle the Timer reached zero or if the mode is changed.

9. “EFFICIENCY” Display. Displays the real time efficiency value on the tissue.

The display shows efficiency range of 0 to 10 (0 being lowest and 10 being the

highest). If the efficiency value is 0, the RF will not be activated. When RF energy

is being delivered, the desirable range of efficiency is 6 to 10, except for Track

Ablation mode where the acceptable efficiency range is 1 to 10.

10. “DEVICE TEMPERATURES (°C)” Display. Displays the temperature readings

of the device thermocouples in whole units of °C. For temperatures out of range

the display will either read “LO” or “HI”. Also, if using a Device with fewer than

five thermocouples, the locations with no thermocouple will display “OP”. If the

Device is not connected, the temperature displays remain blank.

10. “DEVICE TEMPERATURES (°C)” Buttons and LED’s. Each Device

temperature display has an accompanying button with a number on it and a

green LED. Pressing the button switches the LED ON and OFF. When the LED

is ON, the reading of that temperature sensor is used in the temperature control

algorithm. If the LED is OFF, the displayed value is not used in the calculation of

the average device temperature. The last display cannot be deselected in ATC

mode. The displays that indicate “OP” prior to the activation of RF energy are

excluded from the temperature algorithm in ATC mode and their LED’s are OFF.

11. “AUXILIARY (°C) TEMPERATURES” Display. Functions similar to the Device

Temperature Buttons and LED’s.

12. Liquid Crystal Display (LCD) Display. Displays the RF Generator’s current

status and operating information.
