Adjusting Audio Volume
1. Adjust the volume of the audio signal by rotating the Volume Control
Knob on the ESU rear panel (see Figure 5-12 through Figure 5-15).
2. If desired during a clinical procedure, the Volume Control Knob may
be rotated fully counter-clockwise to its lowest setting.
NOTE: At the minimum setting, the tone may NOT be audible during

9. INSTRUCTIONS FOR USE

Once the Electrosurgical Probe has been positioned, RF power is
delivered via the ESU resulting in the coagulation of the targeted tissue.
Temperature can be monitored during the coagulation procedure through
the sensors embedded within Probe electrodes.
1. Follow steps given in the sections, Initial Installation and Powering
ON the ESU.
2. Follow steps given in the Instructions for Use of the Probe.
3. Connect the Probe to the ESU by plugging in the Instrument Cable.
4. Select the desired Probe electrodes with the ELECTRODE
SELECTED Buttons on either the front panel or the ESU Remote
Cable.
5. When the coagulation site has been accessed and the selected
Probe Electrodes are in contact against the tissue surface, RF power
may be delivered as described in Section 8, ESU in RF DELIVER
Mode.
6. RF power is delivered to the tissue via the selected probe electrodes,
resulting in coagulation under the selected Probe electrodes.
Temperature sensors in the electrodes allow temperature control of
RF delivery, resulting in more consistent coagulation without over
temperature effects.

10. TROUBLESHOOTING THE ESU

Indications of ESU Problems/System Faults
RF power delivery can cease due to operating conditions other than user
intervention. To assist the operator, the ESU front panel indicators can
provide indications of anomalous operating conditions and equipment
setup failures.
Front Panel Fault Indicators:
SYSTEM FAULT Indicator is lit when a non-recoverable software or
hardware failure has been detected and the ESU will remain
RF power delivery.
