Tuning The EHY-2000plus has a special radio frequency generator, which must be carefully tuned to the patient. If it is not done, the energy released from the device (in the form of radio frequency) will not heat the patient, but will be lost in the air, cables, and in the internal electronic parts.
Page 30
plus Preparation before treatment The treatment starts with the preparation of the patient for the actual treatment through medicine and psychological attention. After the treatment immunology support is suggested. The most optimal electrode has to be chosen for the treatment. For the suggested electrodes see Appendix 3.

plus To start the RF power output (treatment), just press the START button. • After the start the device tunes to the patient at a low power level. The tuning motor movements are indicated on the display in the Information point.
plus If the tuning is not successful within 90 seconds, the device will indicate it with a sound signal and the “Error” LED will be blinking until the tuning is not successful. In this case the electrode should be re-positioned to reach a better electrical contact with the patient.
plus Time-meters On the front of the device a counter shows the overall running time. This information is for service purposes. On the front of the device another counter shows the summarized treatment time. This is for controlling of the active time of the device. Treatment cannot be provided (device is blocked automatically) in case of any manipulation or damage of the time-meters.

plus Appendix 4 – Refilling of the bolus electrode 1. Please, unplug the cooling water quick connectors and the electric cable connector. The fixing safety button of the power plug has to be pressed down before pulling it out and be kept pressed throughout the procedure. Loosen the electrode fixing bolt, screw and pull it out of the electrode- holder arm.
Page 65
3. Lift up the electrode to such a height that the bolus does not touch the mounting surface. First of all, fill up the electrode with a special liquid provided by Oncotherm to avoid algae formation. Use the small bottle with the label: “Algae control” After this you can fill up the electrode with distilled water in this position.
Page 66
plus 5. Tilt the electrode in a small angle so that the open filling up hole must be higher than the closed one. Please press the bolus up until water appears on the open filling up hole. With this process you de-aerated the bolus. 6.
Page 67
plus Take care that during this process, air must not get into the bolus. Take care that you can continuously see the water in the filling hole. Now, in this position screw in the packing nut. 7. Turn up the electrode and check the appropriate volume of the water in the bolus and that it is de-aerated once more.
Page 68
plus Attention! In the next pictures we are showing some examples of non-proper filling up of the electrodes and we are also showing how to avoid the mistakes. Air must not remain in the electrode because this blocks or misleads the tuning and the auto matching procedure and so suppresses the efficacy of the treatment.
Page 69
plus By pushing the bolus with the entire palm you can reach the metallic electrode plate: not enough water in the electrode. In this case, during the treatment the RF radiator electrode will be too close to the patient and could cause burn. Please fill more water into the electrode. To correct this mistake, go back to point 3.
