| Procedure | Tools Required | Frequency | |-----------|----------------|-----------| | Output power calibration | RF wattmeter, 500Ω load | Annually | | Relay contact cleaning | Contact cleaner, multimeter | As needed (if intermittent output) | | PRE monitor adjustment | Resistor decade box | After main board replacement | | Firmware verification | PC with serial cable | Only if unit shows erratic behavior |

The manufacturer recommends:

Error codes and symptoms (e.g., “no output in Cut mode but works in Coag,” “continuous activation tone”) are mapped to specific test points on the main PCB. The manual lists expected voltage levels at key nodes (e.g., +5V logic supply, +28V RF driver rail).

Detailed electrical input and output characteristics.

Recommended 10 seconds ON and 30 seconds OFF to prevent overheating. Waveforms:

The Ellman Surgitron 4.0 Dual RF line is now part of the product portfolio, which is owned by Hologic . For any service needs, users are advised to contact Cynosure directly.
