Surveillance of the dispersive electrodes is essential for safety, especially for lengthy
ablations. This should occur at the beginning of the ablation, to prevent burns by early
detection of a misapplied electrode. Surveillance is also important during ablation
to detect a pad for which the interface quality is compromised, such as in peeling
or tenting.
To aid detection of poorly adhered or improperly placed return pads, the RF 3000™
Generator has been equipped with the Pad-Guard™ Current Monitoring feature.
Each of the four return pads is monitored for current flow. Current exceeding
0.8 amp results in an error message indicating the high current pad (P1, P2, P3,
or P4) and halts the generator.
Causes for a P(x) error include improper location of pad placement (one pad placed
closer to the active electrode, thus absorbing more current than the other pads)
or poor pad contact with the skin (peeling or tenting).
In case of a P(x) error, all pads should be checked for location (see Figures 3 & 4)
and proper skin contact.
Pad-Guard reduces the likelihood of a skin burn, but does not eliminate it completely.
One should monitor both the pad contact and skin conditions periodically throughout
the procedure.

WARNING! When not in use, the active electrodes should never touch the patient.
Boston Scientific recommends the use of the Boston Scientific LeVeen™ Electrode
or Soloist™ Electrode with the RF 3000 Generator. Deploy active electrodes
according to manufacturer's instructions. Ensure that the active electrode plug
is connected securely to the RF 3000 Generator before proceeding.

• F ollow all CAUTIONS, WARNINGS, and instructions in the following sections:
Introduction, Operation, and Ablation.
• E nsure that the RF Generator is turned on by setting the mains power
switch to "|" . This switch is located on the rear panel on the power entry
module (where the power cord attaches).
