Trouble with your Model A? It’s rare, and it’s likely due to user error which we can easily remedy through coaching. On occasion, however, people grapple with it themselves rather than calling us and sometimes resort to sending their machine in to JWLABS for testing.
Of the few machines which are sent back for our review, 99% of them are due to user error which could have been resolved over the phone. For this reason, we are reviewing our brief troubleshooting tips.
Problem: Burning or irritation of skin at site of electrode patch placement.
If using self adhesive patches, replace with new ones. With continued use, the adhesive on the patches degrades and interferes with the quality of your contact.
Check the pins on ends of electrode wires. If they have become blackened from carbon build-up, use a fine emery board or sand paper to clean.
Some people are more sensitive to this burning than others. For this reason, we advise that you not place the patches on sensitive areas without JWLABS coaching.
We train our Model A users to place electrode patches on the palms and/or the soles of the feet. This is because in these areas the skin is more robust than more sensitive areas. Patches may be used in the more delicate areas, but we advise that customers be personally coached for these special applications.
For those who are particularly inclined to have skin irritation, we provide coaching for special techniques with the carbon patches which are included in the start-up kit.
In general, it is advisable to re-position the patches every ten minutes or so, especially if placement is other than on hands and/or feet.
Problem: No green activity light.
Make sure the input cable is securely connected to the headphone jack of your media player. Occasionally, the fit of the plug into the jack requires some adjustment. This is due to very slight variations of the measurements of the components.
Adjust the volume of the media player to maximum. When using a computer, this requires that you check settings in several places: keyboard, sound system adjustment in control panel, etc.
Note that if using a cd player, the volume setting will often default to zero when you change the batteries. Do not assume that you are at maximum volume.
Problem: No output.
First, make sure your activity light is illuminated to bright green. If this is in place, check your connection at the electrode jack. Your electrode wires must be firmly in place.
Another possibility is that there is a break in one or more of the very fine wires that compose the electrode wires. In this case, they will need to be replaced.
