Notes

• The ratings above are maximum values; actual outputs may vary by ±20% as specified.
• Peak voltage and crest factors change with selected power levels and loads.
• Power can be reduced during procedures by adjusting the settings to achieve the required clinical effect.
• Always use the lowest effective power setting compatible with the intended surgical outcome.
