Disintegration of vinyl case - Graham Whyte - 04-06-2003 I have not used my 33-E for about six months and when I opened the vinyl case today I found the inside of the case is in the process of disintegrating. This has shed a black dusty deposit all over the calculator. Question - is this disintegration common, and any ideas what causes it happen? The calculator is normally stored in a cool dry place.
Thanks.
Re: Disintegration of vinyl case - Gordon Dyer - 04-06-2003 The same thing is happening to my 41CV case. Disintagrating inside and producing black dust, so I have stopped using that one. It was like that when I bought it 6 months ago. I guess it is caused by damp, or maybe inappropriate washing, but I'm not sure.
Re: Disintegration of vinyl case - David Smith - 04-06-2003 This is very common. The backing to the lining turns to dust. Just take the case and toss it in the washing machine. Then prop open the case and let it air dry. In tough cases you may have to wash a second time.
Re: Disintegration of vinyl case - Raymond Del Tondo - 04-07-2003 One of my HP-41 soft cases shows the same black dust.
How many degrees (Celsius) can the case handle, Re: Disintegration of vinyl case - Norm - 04-07-2003 Did anybody ever compare the size of a 41C to
Then a person could probably buy a brand-new Re: Disintegration of vinyl case - Richard Garner - 04-07-2003 The 41c+card reader is the same size as the 48g, so the cases can be used for either.
I would think it would be very loose w/o the reader though... (NM) - Jeremy - 04-07-2003 !@#$
Re: Disintegration of vinyl case - David Smith - 04-07-2003 I'm pretty sure 30C would be fine. I set my washing machine to HOT, but tend to keep the house water heater set fairly low compared to most people... I don't like the idea of people being able to scald themselves... but still need to dial in cold water to take a comfy shower.
