Ok we're ready to set the first of our electrodes. Again, we'll start at the bottom and work our way up.

So, take the leg-movement sensors and ensure that each has two 'sticky-dot' electrodes attached (if one or more are missing, take some of the spares in the pack and 'snap' them in place on the sensor).

If either short or long-legged sleepwear is to be worn, running each sensor down the pant leg from the waist will help avoid the leads getting tangled overnight. 

Peel off the back of the adhesive on each of the electrodes and stick the sensors down on the prepared areas of the legs. The sensors are labelled 'L' and 'R' which refers to the participant's left and right legs.

Plug the black connectors into any of the ports along the top of the SomnoHD.
