I've been so grateful that my van is fine after the heavy rains. Well, not so fast Sue. The lockdown seems to be working to secure my chair in place while I drive but the shrill sound that indicates I'm not reaally secure won't stop ringing. Is it a matter of turning of the buttton, adjusting a wire, or getting me an entirely new system? Am I really secure or does it just seem so? Has anyone else ever had that problem? I know if I call I'll be told to bring it down and pay $$$$$$. Withth dumb safety concerns for handicapped drivers I may be forced to once I have to get it recallibrated. Then they'll tell me they must send away for it and it can't leave the shop till it's installed! Oh how I wish I knew what to think! I know a guy who lives at Umbrella Works and used to install the eqipument. I may just seek him out.
