### Step 2 - Removing the support layers

Using the transparent tabs, remove the 2 sections of the transparent layer with one hand. With your other hand, secure the attachment of the electrodes.

Verify that the electrodes are connected: press the patch firmly on your skin using your hands and verify all electrodes and strips are well connected.
