4.1  A Note About Electrodes

 

To ensure safe operation of the Sys*Stim 294, follow the recommendations listed below: 
1.

 

We strongly encourage careful maintenance of the electrode system. This includes the 
lead wires as well as the pads themselves. Worn cables and/or poor pads (or the 
wrong sized pads) can have a significant impact upon treatment results. 

2.

 

For best performance, use Mettler Electronics’ brand electrodes. 

3.

 

Do not exceed the number of recommended uses listed on the instructions for EZ 
Trodes or other reusable self–adhesive electrodes. 

4.

 

Make sure that the entire surface of the electrode is contacting the patient. 

5.

 

Do not use moist hot packs to secure electrodes. 

6.

 

To avoid skin irritation due to high current density, do not use electrodes smaller in 
surface area than the 2" diameter EZ Trode® self-adhesive electrode (ME 2221). 

7.

 

Do not use conductive carbon electrodes with this product. 

8.

 

Whenever clinically possible, utilize the largest possible pads to reduce local increases 
in current density. In situations where small pads are required, use the lowest 
stimulation intensity necessary to achieve the desired clinical results.
