Beyond the Basics

muting the alert tone

To temporarily mute the alert tone, press MUTE during a highway warning alert. The alert tone stops and MUTE

flashes until the alarm cycle finishes (3 minutes). To mute all alerts, hold down MUTE for 2 seconds. The scanner beeps twice and MUTE lights. Mute automatically resets when you turn your scanner off.

adjusting alert

ALERT has three settings: Bright, Dim, and Off. Repeatedly press FLASH to select Bright, Dim or Off. ALERT flashes and

the alert tone beeps. If you select Off, appears to remind you that ALERT is off.

Turning off ALERT and muting the alert tone turns off the

 

highway warning alert.

skip frequencies

To skip a frequency, press L/O. You can program up to 50 skip frequencies into the highway patrol priority frequency channel. You can also program up to 100 skip frequencies for other frequencies (see “Frequency Skip”). If you change the state code, skipped frequencies are cancelled as soon as scanning starts.

highway patrol priority channels

Each state preprogrammed in the scanner contains a number of highway patrol priority channels. Your scanner automatically checks a state’s priority channels every 2 seconds for activity. If there is activity on one of the priority channels, ALERT flashes and the alarm tone beeps (see “Highway Warning Alert”). You will experience a slight interruption in the conversations you hear as the scanner checks the priority channels. You can cancel the priority

PRO-2051 specifications

The Radio Shack PRO-2051 is a standout model in the realm of scanner radios, known for its advanced features and user-friendly design. This unit is particularly favored among hobbyists and professionals alike for its superior performance in receiving a wide variety of radio frequencies.

One of the main features of the PRO-2051 is its wide frequency range, which spans from 29 MHz to 1.3 GHz. This includes the VHF and UHF bands, allowing users to listen to everything from public safety communications to amateur radio. The scanner also supports trunked radio systems, specifically the Type I, Type II, and Motorola systems. This makes it an invaluable tool for monitoring emergency services and other business communications that rely on trunking technology.

The PRO-2051 is equipped with an extensive memory bank, allowing users to store a significant number of channels. With 200 channels available and multiple banks, users can easily segment frequencies for various agencies, events, or interests. The scanner's capability to store frequencies in a user-friendly environment makes it easy for enthusiasts to quickly access the channels they most frequently monitor.

Another noteworthy characteristic is the scanner’s ability to utilize CTCSS and DCS tones. This feature helps eliminate unwanted noise by only allowing signals that match preset codes to be heard. This not only enhances clarity but also allows users to filter out unrelated conversations.

The PRO-2051 includes a backlit display, ensuring that users can read frequency and channel information even in low-light conditions. The front panel’s intuitive layout, featuring a simple keypad for inputting frequencies, adds to the overall ease of use.

Another significant aspect of the PRO-2051 is its ability to serve as a conventional scanner with features like Search Mode and Priority Scan, allowing users to quickly locate active frequencies. Furthermore, the scanner supports "Close Call" technology, which enables it to automatically detect and tune into nearby transmissions, ensuring users don’t miss important communications.

In terms of power, the PRO-2051 is designed for both AC and DC operation, providing versatility for both home use and field operations. This flexibility, combined with its advanced features and robust design, makes the Radio Shack PRO-2051 a top choice for anyone looking to explore the vast world of radio communications.
