Select RF Delivery Settings
Use one of the methods below to select RF Delivery settings for a procedure.
• Recall RF Delivery settings stored with the Memory Buttons.
• Manually set the RF Delivery settings as described below.
Control-Mode Selection
• WARNING: With non-irrigated catheters, start with a low temperature setting in temperature-control
mode, and then slowly titrate the temperature setting up to achieve the desired effect. With irrigated
catheters, select power-control mode with a temperature setting intended to ensure that adequate fluid
is irrigating the tip of the catheter.
The mode of operation can be toggled between Power-Control Mode and Temperature-Control Mode by
pressing the Control Mode Button while the unit is in STANDBY mode (The control mode button is inactive
during RF power delivery).
The control-mode selection determines the effect of the Power and Temperature settings.
• In Power-Control Mode:
• The amount of RF power delivered will equal the power setting unless the measured temperature
exceeds the temperature setting.
• The temperature setting is a limit for catheter tip temperature. If the limit is exceeded, power will
be reduced or halted to lower the measured temperature below this limit.
Note: When power is reduced or halted, an operational message or diagnostic code will appear in the
front panel display. See OPERATIONAL MESSAGES Section, or DIAGNOSTIC MESSAGES Section for
additional information.
• In Temperature-Control Mode:
• The power setting is a limit. The RF Generator is allowed to adjust RF power delivery up to this
limit to achieve the target temperature.
• The temperature setting is the target temperature.
Note: The target temperature may not be reached if the power setting (limit) is reached.
The default control modes for BSC Catheters are listed in Table 3. When a catheter is initially connected,
the RF
Generator automatically switches to the default control mode for that catheter. However, the user
may switch control modes by pressing the control-mode button.
