Our first step will be to prepare the recording sites on your skin to ensure clear and precise signals.

​

We will first clean each site with the alcohol wipes provided, cleansing the area for 5-10 seconds (the wipes will dry out as you go, and you should replace them as this happens, but you should only need around 5-6 wipes in total).

​

Then we will apply small amount of abrasive gel to a cotton tip (see the photo for an example of how much is appropriate for each site) and gently exfoliate the skin for at least 30 seconds or until the gel has been absorbed. Like the alcohol wipes, you may need to replace the cotton tips as necessary as you go.

We have provided an example order of the sites to follow. Click 'Next' and mark each off as you proceed.
