Some of the original cables weren’t working correctly, so the technician is having to redesign them. It’s quite a complex issue that needs significant research and development, which is taking time. I’ve worked with the technician for many years and he’s very good at what he does, so he will resolve the situation. If you have any problems with your existing cables, let me know exactly what you find. Most of them are perfectly fine. About 1/3rd are affected. It more depends on the original components and circuit board that was used. The other option is use the wireless button, but to use it as a toe switch it will also need modifications. I appreciate everyone’s patience. I have regular contact with the technician and the resolution isn’t far off.
