Audio Volume
The audio levels stated below are for activation tones (cut, coag, and bipolar) and alarm tones (return electrode and
system alarms) at a distance of one meter. Alarm tones meet the requirements for IEC 60601-2-2.
Activation Tone
Alarm Tone
Return Electrode Sensing
The system presents audible and visible alarms when it senses no return electrode.
Low Frequency (50-60 Hz) Leakage Current

Volume (adjustable) 45 to 65 dB
Frequency Cut: 1 kHz
Blend: 1 kHz
Coagulation: 2 kHz
Fulguration: 2 kHz
Bipolar: 2 kHz
Duration Continuous while the generator is activated

Duration 2 seconds
Solid
Trip resistance: 0 Ω to 5 Ω ± 3 Ω
Continuous measurement:
Once the system establishes the solid return electrode resistance, an
increase of 20
Ω ± 5 Ω in resistance will cause an alarm. When the
alarm condition exists, the system deactivates output power.
Split
Trip resistance: 10 Ω ± 5 Ω to 135 Ω ± 10 Ω
Continuous measurement:
Once the system establishes the split return electrode resistance, an
increase of 40% in resistance will cause an alarm. When the alarm
condition exists, the system deactivates output power.
