TC26 Trainer’s Cap System

Tips for getting a good signal

We’ve discovered a few tricks that can help trainers achieve better connections:

• Pre-soak the assemblies for 24 hours before the first use. This significantly reduces frustration during setup. We recommend keeping the assemblies soaking continuously.
• Silver electrodes tend to last about six months if kept soaking, before developing a film that causes signal issues. To extend their life, you can remove the electrodes each evening, rinse them, and let them dry. Leave the assemblies and sponges soaking and reinsert the electrodes at the next session.
• For improved signal quality, using a damp Q-tip with saline or applying a light spray (as you suggested) can be helpful. Be careful not to wet the surrounding areas, as this can create a saline bridge and potentially cause an EEG blowout.
• Loose caps can be problematic if the sponges aren’t pressing firmly on the scalp. Also, a loose chin strap can affect mastoid placements.
• For participants with short hair, mastoid placements tend to work well when the chin strap is snug.
• For those with long hair, placing it in a low ponytail (with the tie below the cap) or using ear clips may yield better results with mastoid/reference connections.

Re-using your silicone covered electrodes

Sintered silver chloride electrodes from the original TC26 for gel can be used for the TC26-s (saline) but with a silicone cover. To avoid purchasing new electrodes, you can remove the silicone covers from your electrodes easily. This video shows how.
