c. Switching Handle (1). Both the 711-SW handle and the 711-B needle
electrode are shown.
d. BIPOLAR Outlets (2). You use the BIPOLAR outlets for bipolar (bi-active or bi-
terminal) coagulation techniques. The BIPOLAR outlets are of equal power. The 789 set
is available with two tips, one for each BIPOLAR outlet. Single needle techniques require
that an indifferent plate electrode (Birtcher 706) be plugged into one of the BIPOLAR
outlets and the tip for the electrode handle be plugged into the other.
e. LOW Outlet (3). The LOW outlet is a single active terminal. You use it for light
desiccation and fulguration techniques requiring low intensity, or monoterminal current.
f. HIGH Outlet (4). The HIGH outlet is a single active terminal. You use it for
heavier desiccation and fulguration techniques requiring higher intensity or monoterminal
techniques.
g. ON/OFF Pilot Light (5). The ON/OFF pilot light lights only when you turn the
control dial (item 7) clockwise from the OFF to ON position.
h. ACTIVE Circuit Pilot Light (6). The ACTIVE pilot light lights only when you
activate the foot switch or hand switch.
i. Control Dial (7). You use the control dial to select current intensity from "0"
(MAINS OFF) to "100" (MAX).
j.
Audio Adjust (8). You use the audio adjust dial to control the buzzer level
volume.

TECHNIQUE CONFIGURATIONS
a. Monoterminal Configurations. For monoterminal fulguration and desiccation
procedures, use either the HIGH or LOW terminal outputs only. Grounding is achieved by
the third wire in the line cord. You can use the 741 sets in this configuration.
b. Monopolar Configurations. This technique delivers power for coagulation
from one terminal of an ungrounded BIPOLAR output of a return through the indifferent
plate. You may use the 771A, 711E, and 779-3 handles, the 741 set, or forceps in this
configuration.
c. Bipolar Configurations. Bipolar electrodes actually determine the path of the
therapeutic current in the area to be coagulated. Bipolar coagulation does not allow the
current to flow through the surrounding organs or tissue. You may also use the 782 and
789 sets in this configuration in place of the forceps as shown in figure 1-2.
