I come here yesterday to post not so much a whine but in the end lotsa cheese!
For those whose pwc's have the head ar ray: After waiting almost 9 months, my 400 pound baby was delivered without complications. Said baby became a useless item, no longer providing me the pleasure of its company. The 5000 dollar head ar ray stopped working, returning me to either the bed or the old black ford (husband calls the new wheels my BMW). A call to Dave, my D M E, and about 5 days later, comes with tools in hand.
Now, it really isn't useless as there are attendant controls on the back of the chair. But that means you are not in control, they are. Not too, bad but easier to use manual chair. Well Dave fixes in less than 2 minutes. Apparently, SOMEONE, flipped a little switch turning off my controls. The attendant switch was off (a good thing), but its important to have my switch in the right direction, also.
So, for all you togglers, when you upgrade to the head ar ray, check the switch. I can honestly say, "I didn't do it!"
