External Trial Stimulator 2 (ETS 2) Maintenance
The ETS 2 is used to conduct intraoperative stimulation testing during the lead implantation
procedure. Refer to the DFU listed on your DBS Reference Guide for detailed procedure and
guidelines for intraoperative testing.
To turn stimulation on and off on the ETS, press the ON/OFF button on the ETS 2 (Figure 1). When
the stimulation is on, the Stim Indicator Light will blink green. The ETS 2 runs on two AA batteries
that are provided with every ETS 2 kit. When the batteries need replacement, the Battery Indicator
Light will change from a flashing green to a flashing yellow.
To install new batteries:
1. Confirm that stimulation is OFF by confirming that the stimulation indicator light is not blinking.
2. On the rear of the ETS 2, push in slightly and slide down the battery compartment cover.
3. Remove the old batteries.
4. Place two new AA batteries in the slots matching the positive (+) and negative (-) markings in
the compartment.
5. Align the battery compartment cover on the case and slide the cover into position until is snaps
closed.
6. Both the Battery Indicator light and the Stim On indicator lights will emit an amber glow for 15
seconds after which the Battery indicator light blinks green.
Vercise PC Stimulator Battery
The Vercise PC Stimulator has a non-rechargeable battery. The longevity of the Stimulator battery
depends on the following factors:
•
Programmed parameters
•
System impedance
•
Hours per day of stimulation
•
Changes to stimulation made by the patient.
For additional information on estimating the longevity of the non-rechargeable battery, refer to the
appropriate programming manual as listed on your DBS Reference Guide.
