The number of available electrodes which may be selected depends on the
probe type. At least one electrode must be selected to enable RF delivery;
otherwise, the ESU remains in STANDBY and emits the Error tone if the RF
ON Button is pressed.
A defective probe electrode may not be selected. If a probe electrode is not
selectable, the ESU emits the ERROR tone when the corresponding
ELECTRODE SELECTED Button, immediately below the indicator, is
depressed and the SELECTED ELECTRODE LED will not illuminate.
Figure 5-7: ELECTRODE SELECTION Buttons and LEDs
Depressing an ELECTRODE SELECTED Button alternately enables or
disables that electrode. During delivery of RF DELIVER mode, the
ELECTRODE SELECTED Buttons are not operable; they can only be used in
the STANDBY Mode.
SELECTED ELECTRODE Indicators
Each of the seven SELECTED ELECTRODE green indicators (see Figure
5-7) displays the status of a probe electrode. If the Indicator is continuously
illuminated, the electrode is enabled for RF power delivery. If the Indicator is
NOT illuminated, the electrode is disabled and will not deliver RF power.
During the DELIVER Mode, the Selected Electrode Indicators display those
electrode(s) being used to deliver RF power.
Electrode(s) in which problems have been detected will have a corresponding
flashing Indicator.
ISOLATED PATIENT Connectors
NOTE: The 40-pin ISOLATED PATIENT CONNECTOR is provided for future
use only.
The ISOLATED PATIENT CONNECTORS (see Figure 5-8) provide for
connection of the Instrument Cable and/or Electrosurgical Probe to the ESU.
Two connectors are available. On the left is a 30 position connector. On the
right is a 40 position connector. A sliding door covers the unused connector.
The connectors have locking mechanisms for secure cable installation and
are keyed for proper alignment of the mating plug.
