Note: Calibration should only be performed using specialized non-inductive test loads and a high-frequency oscilloscope or specialized ESU analyzer.

Do not spray liquids directly onto the housing slots; use a dampened cloth to avoid internal dripping onto the high-voltage transformers. Reassembly Checklist

The service and instruction manuals for the Ellman Surgitron 4.0 Dual RF

A: No. The 4.0 Dual RF has a second frequency (1.7 MHz) and different output relay logic. The 2.0 manual lacks the bipolar/dual-frequency calibration procedures.

Internal circuitry contains potentials exceeding 1000V peak-to-peak during RF generation. Do not probe the mainboard blindly.

Check the AC outlet power. Inspect and replace the rear-panel fuses with the exact rated replacements.

) and high-frequency leakage current matching standard IEC 60601-2-2 guidelines. Calibration and Waveform Verification

Pro tip: When searching, include the serial number range. Early 4.0 units (SN < 5000) used a different RF output board than later units (SN >= 5000). The correct service manual will list both schematics.
