2.8.1.2 Dual Dispersive Electrode Alarm
If a Dual Dispersive Electrode alarm condition
occurs, check the Dual Dispersive Electrode Status
/ Alarm Indicator for clues to the problem:
a. If only the Dual Dispersive Electrode Status/
Alarm Indicator flashes red, the resistance is
too high. This can be caused by inappropri-
ate choice of a site for the dispersive elec-
trode, a broken cable or poor connections to
the ESU.
b. If both the Single and Dual Dispersive
Electrode Status / Alarm indicators flash red
in unison, the impedance is too low. This
condition can be caused by a short in the

dispersive electrode, or some fault within the
ESU. Replace the dispersive electrode while
ensuring the dispersive electrode makes con-

Acc Codes
Acc Codes are most often caused by faults in
accessories connected to the ESU. The fault can
often be corrected in the operating room with-
out a service call. The following list gives the
meaning of each code. For each code, check the
indicated accessory for proper operation. If the
fault persists, unplug the accessory, turn the ESU
off and then turn the ESU back on. If the fault is
still present, call a Hospital Qualified Biomedical
Technician for assistance.
