2.0 PRODUCT DESCRIPTION

This Section contains relevant "Quick Start" excerpts of the technical data supplied in the Hyfrecator® 2000
Operator's Manual, Cat. No. 7-900-OM-ENG. Refer to that document for further details.
2.1 Controls, Displays and Connectors
The Hyfrecator® 2000 controls are marked with IEC and ISO symbols which should be familiar to an
experienced biomedical technician. See the Operator's Manual, Section 3, for detailed definitions.
• Mains Power
AC Mains power is controlled by a rocker switch on the right-hand side of the unit. Mains power is
supplied by a 3-conductor cord connected to the CEE-22 mains inlet on the bottom of the unit. This cord
MUST be connected to a safety-earthed AC mains source corresponding to the unit's mains rating marked
on the rear. The green-yellow lead in this cord serves to return monopolar RF current to the unit through
the patient's body capacitance to earth.
• Mode Selection
A three-position slide switch marked "HI - LO - BI" sets the operating mode. This switch also exposes only
the RF output jacks appropriate to the selected mode. The active accessory RF plug must be disconnected
from the RF jacks to allow movement of the mode switch.
• Power Adjustment
RF output power may be adjusted using either the power control knob or the up/down push-buttons on the
handswitched active accessory. The selected power in watts to rated load appears on the two-digit LED
display. HI and BI may be set in 1 W increments from 0 to 35 W , and LO is adjustable from 0.0 to 9.9W
and 10 to 20 W . Note that each mode has its own independent power setting.
• Output Activation
Activation of RF output is controlled by either a handswitched accessory or an optional footswitch
connected to the four-pin quick-release connector on the bottom of the unit. Activation is accompanied by
illumination of the blue LED below the power display and a steady, audible tone.
• Tone Volume
The activation tone volume may be set using the screwdriver adjustment on the rear panel. The tone
remains audible at the minimum setting.
• RF Output Connections
P/P (Patient Plate): Recessed male 0.08" (2 mm) pin for connection to the optional Patient Plate cord.
Serves as an RF current return pole for Monopolar output. It is also capacitively coupled to earth via the
mains cord to couple return current through the patient's body capacitance when a patient plate is not in use.
HI and LO: Monopolar active output, capacitively referenced to earth and the P/P jack. Intended for
connection to the 0.25" (6 mm) RF banana plug on monopolar active accessories.
