Painstakingly created by Marksscanners, this 48 page Easier to Read Scanner Manual takes you deep into the amazing feature set and instructions for their two original GRE portable and base/mobile trunking scanners (non-digital) as well as GRE-built current and older model RadioShack scanners:

GRE Models:
PSR-300
PSR-400

RadioShack Models:
PRO-97
PRO-2055
PRO-163
PRO-164

This is an extremely handy 5.5 X 8.5 perfect-bound book which you can use on your desk, in your car and on the go. The guide is in 4-color with charts, images and super detailed text. This one guide covers all four of these GRE and RadioShack model scanners and takes you far beyond what you get with the radio. Go step-by-step through each of the dozens of features of these scanners and learn what the functions do and how they are enabled and disabled.

Mark takes you through the process of planning systems, sites and groups and then programming your scanner with this information. The GRE/RadioShack scanners are remarkable radios but to get the most out of them you really need this ultimate manual we are proud to offer. Note that if you have the newer GRE PSR-310 or PSR-410 scanner please see another volume which covers those radios.
