Thank you for purchasing your Pro-2051 1,000-channel,
triple-trunking scanner from RadioShack. Signal stalker
allows you to lock on frequencies within 1,000 feet, without
programming. The PC interface lets you program your
scanner using your computer. Support for Motorola, LTR and
EDACS trunked systems permits you to access most any
police, fire and emergency system. With built-in Skywarn,
you will be able to stay up to date with the reports called in
by storm spotters.
