DESCRIPTION
RF/Stimulus Output
OFF
RF power is not delivered during this state.
FAULT Indicator
OFF
(The FAULT indicator is used only in the POST and SYSTEM FAULT states.)
RF/Stimulus Output ON/OFF
Indicator
OFF
The indicator is not illuminated during this state, as there is no RF power delivery.
Measurement Window
ON
Active impedance measurement is displayed. The display will read HIGH for high impedances
(e.g., open circuits).

None for RFA MODE –
THERMOCOUPLE
Placement state
In the Secondary Thermocouple Placement state, Treatment mode is not selectable.
In the TDP A Placement state, Treatment mode is available. If the position of the switch on the
Switching Cable changes to TDP B, the Generator changes to the TDP B Placement state, and the
Treatment mode key is not selectable and the mode select key is greyed out.
In the RFA Placement state, Treatment mode is available if the position of the switch on the
Switching Cable concurs, or if only the RFA Y-Connecting Cable is used. If the position of the switch
on the Switching Cable does not concur, TREATMENT mode is not selectable.
When Treatment mode is selected, the Generator will enter the READY state of that mode.
The Generator dynamically changes the selection availability of the Placement mode and
Treatment mode key via monitoring the switch position in the switching cable, and displaying the
appropriate text in the Graph Window.

Continuous audio output is generated for
placement. Frequency of output is related to
active impedance measurement. No audible tone
if selected probe is an open circuit – replace with
warning message. This feature can be disabled
in the AUDIO SETTINGS state, accessible from the
ADVANCED SETTINGS mode.
