Radio Shack Office Equipment & Supplies - Recent Questions, Troubleshooting & Support

Try looking at your screen resolution settings on your laptop. For Windows right click on the desktop screen then click screen resolution, or display settings and see if the projector is recognized on your laptop. If yes try changing the resolution as the laptop may be trying to connect at a resolution that isn't supported by the projector.

In recent years public service and all land mobile has moved to narrow band FM from the old 12.5khz or 5khz bandwidth FM to new 2.5 and 1.25 khz format. The older scanners will play these transmissions with much lower volume and there is nothing that can be done to the scanner to solve this. You can buy an amplified speaker and use that to further boost the audio or just replace the scanner with a new scanner built by Uniden or GRE (General Research Electronics) who make almost every scanner on the market. Both are good units.

A Porelon #11201 PR12 Calculator Ink Roll (purple) ink cartridge works well in mine. If nowhere else, I think you can find them on eBay. You might want to put on a latex glove when you change it out, it gets purple ink on your fingertips.

The feed roller turns to mush on these old calculators. I suspect that is the problem with this one. You might get it to work if you replace the mushy roller by a new piece of rubber tubing. However, you have to be mechanically inclined to take the printer apart enough to get to the mushy roller. I have this exact same calculator in my hand right now and when I folded printer paper on a 45 degree angle and forced it through the printer until I could pull it through, the paper was gooed up down the center where the mushy roller rubbed off onto the paper. The calculator still works great electronically!
