To turn stimulation on and off on the ETS, press and release the ON/OFF button on the ETS

(Figure 1). When the stimulation is on, the Stim Indicator Light will blink green. The ETS runs on

two AA batteries that are provided with every ETS kit. When the batteries need replacement, the

Battery Indicator Light will change from a ashing green to a ashing yellow.

Ensure that stimulation is off (the indicator light is not blinking) before opening the ETS battery

compartment.

To install new batteries in the ETS:

1. Conrm that stimulation is OFF by conrming that the stimulation indicator light is not blinking.

2. On the rear of the ETS, 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.
