this warning should be made. Finding the root of the issue is best, but any EMG channel can be toggled off
temporarily until further diagnosis can be made. Coapt does not recommend leaving EMG channels turned off
long term nor turning too many channels off at once; a limited number of active EMG inputs can significantly
limit control performance and prosthesis function.
A few things to look for when diagnosing problematic EMG signal contact:
1.
Ensure all Dome Electrodes are clean and free of residue (clean as necessary with damp cloth and mild soap).
2.
If skin is significantly dry or hair-covered, allow a few minutes for “settle-in”. Speed up this process by
dampening the skin area before prosthesis donning.
3.
Ensure all Dome Electrodes maintain reliable contact with the user’s limb throughout their range of
motion and during their muscle contractions.
4.
Ensure all EMG wire connections to the Dome Electrodes are tight. Always tighten and secure with the
provided split-lock washers to prevent loosening.
5.
Ensure the EMG Connection Cable is fully connected to the Coapt controller main unit.
The EMG Inputs display is showing warnings on some of the channels, what do I need to do?
The Coapt system has built-in detection to know if any EMG channel is not receiving signals from the skin.
Before you can expect good prosthesis control performance, corrective action for any EMG channel showing
this warning should be made. Finding the root of the issue is best, but any EMG channel can be toggled off

Some of the prosthesis’ motions are backwards/opposite.
1.
Ensure all wired connections to the prosthetic device(s) are correct according to the Coapt Device Cable
Connection Guide for the cable type of your prosthesis (e.g. “H0”, “I4”, etc.)
