The Pro-2055 was manufactured for Radio Shack by GRE America Inc

The same scanner as the Pro-97 but as a base/mobile. Trunk tracker three technology. Can use Win97 to program with your computer. Note that due to firmware limitations, computer control is not possible.

This unit can be used as a desktop scanner or mounted in a vehicle.* Alphanumeric display shows ID code or can be programmed with service name. Backlit display and keypad for low-light use. Clones with the popular PRO-97 handheld scanner (#20-527).

Also see the Pro-97 page. All utilities and links listed there also apply to the PRO-2055.
