Fortress Scientific 655FS Hello, we have a

Is it a fortress scientific 2000? with the small console and 5 position
speed knob and the 1/4 inch phone jack "key"?

Its broken and there is no simple solution for your problem. Technically, a repair may be possible, but you'd need some spare parts, decent soldering equipment suited for surface mounted devices, and a lot of experience in handling them.

I understand your sentiment (I hate to throw away things, too!). However, the calculator comes new for below USD 16 even if you mail order it from Canon directly (my estimate is, you can get it for around USD 10 from a local office suplies shop). Ordering the spare parts alone, even if you can identify them, will already exceed the costs for just buying a new calculator, so its a total loss.

Part of the program's design is to block both local and removable drives. That is supposedly one of the options, so the admin may be able to change that.

This is the easiest way (besides random drops).And its free,so...If you have some spare time,just enter there,go to the ''raffles'' section and try ''Public raffles''.All you have to do is to click ''Enter raffle'',and you have a little chance to win.But there is no raffle limit you can join,so,sometimes you will win!Good luck!

Sorry to say but Fortress Scientific quit making power bases many years ago, parts are obsolete. If you can find a wheelchair dealer that stocks Ottobock seating components, their hardware is very similar and may fit.

Your break release shifter is in the push the scooter mode. Put it back in gear and the horn doesn' beep and it should run..
The horn beeping is the alarm to tell you the break release is on.

It is usually located under the seat on the body of the top of the battery housing. Looks like a stick with a ball on it.

Flight Systems Inc is a company in PA that rebuilds/repairs most controllers for powerchairs. You can call them with your specs to see if they can help, and, they are cheap compared to a new controller! Here's their address and they have an 800 number too.

Good luck!

No spare parts available, you will need to buy a new one

Hello,
The functions are many, and the only way to master them is to have the user guide for the calculator ready at hand. Read sparingly, focussing on the problem at hand. By constant practice you will soon use it as pro.

Here is the link to the calculator's guide.

Hope it helps.
