RF POWER CONTROL Button/Indicator
The RF POWER CONTROL button (see Figure 5-6) contains an integrated
yellow Indicator light. It controls the two operational modes of the ESU:
•
STANDBY mode – This mode does not deliver RF Energy to the
attached Probe and allows the operator to adjust the setpoint
parameters.
•
RF DELIVER mode – In this mode the ESU delivers RF power to the
attached Probe.
Figure 5-6: RF POWER CONTROL Button and Indicator
When the ESU is initially powered on but no Probe is connected, the RF
POWER CONTROL Indicator is not lit.
When the ESU detects that a probe is connected, the RF POWER
CONTROL Light flashes, indicating the ESU is in the STANDBY mode and
prepared for RF power delivery.
Pressing the yellow RF POWER CONTROL Button once places the ESU into
the RF DELIVER mode and allows the probe to transfer RF power to the
tissue. In this mode, the RF POWER CONTROL Indicator is lit continuously.
When the treatment is completed, either by the Timer expiring or the operator
manually turning off the RF energy, the ESU returns to the STANDBY mode
and the RF POWER CONTROL Light resumes blinking.
When the user initially presses the RF POWER CONTROL Button to enter
the RF DELIVERY mode, a quick test of temperature sensor functionality is
made prior to delivery of RF power. If the ESU detects a defective probe with
faulty temperature sensor(s) on more than one electrode the ESU does not
enter the DELIVER mode. It re-enters the STANDBY mode and illuminates
the REPLACE PROBE LED, indicating a faulty probe has been detected.
Also, the ELECTRODE SELECTION LED(s) for the defective electrode(s)
blinks.
ELECTRODE SELECTION Buttons
The ESU is capable of delivering RF power and maintaining a desired set
temperature on up to seven electrodes simultaneously. Seven ELECTRODE
SELECTION Buttons (see Figure 5-7) located on the ESU Front Panel are
used to select one to seven electrodes, depending on probe configuration, for
simultaneous RF delivery.
