Audio Volume
The audio levels stated below are for activation tones (bipolar, cut and coag) and alarm tones (return electrode and
system alarms) at a distance of one meter. Alarm tones meet the requirements for IEC 60601-2-2.

Return Electrode Sensing
The system presents audible and visible alarms when it senses no return electrode.

Trip resistance: 0
Continuous measurement:
Once the system establishes the single-plate electrode resistance, an
increase of 20
alarm condition exists, the system deactivates output power.
Trip resistance: 10
Continuous measurement:
Once the system establishes the split-plate electrode resistance, an
increase of (35 ± 5)% in resistance will cause an alarm. When the alarm
condition exists, the system deactivates output power.
