Last evening I started to raise the automatic foot/leg rests and a red warning light by the switches started flashing. Then an ICS "legs error 209A" appeared in the LCD. Everything but the leg rests still worked. This morning everything seemed screwed up and only worked intermittently. The tech checked all the easy stuff like wire connections but all seems well. He took it to the shop to start tearing it down. I only got the chair last August. I was disappointed to learn that the Intelligent Control System (ICS) is not very smart. The error code does not pinpoint the problem.
In the meantime, I am back in my Quickie GT and my shoulders are already starting to scream. I will keep you posted.
