SPECIAL FEATURES

DELAY

Many agencies use a two-way radio sys- tem that might have a pause of several seconds between a query and a reply. To avoid missing a reply, you can pro- gram a 2-second delay into any of your scanner’s channels or frequencies. Then, when the scanner stops on the channel, DLY appears and the scanner continues to monitor the channel for 2 seconds after the transmission stops be- fore it resumes scanning or searching.

You can program a 2-second delay in ei- ther of the following ways:

•If the scanner is scanning and stops on an active channel, quickly press DELAY before it starts to scan again.

•If the desired channel is not selected, manually select the chan- nel then press DELAY.

If the scanner is searching, press DELAY during the search. DLY appears on the display and the scanner automatically adds a 2-second delay to every trans- mission it stops on.

To turn off delay on any channel, select that channel then press DELAY. DLY dis- appears. To turn off delay for all frequen- cies during a search, simply press

DELAY.

SKIPPING FREQUENCIES/ CHANNELS

You can scan channels faster by skip- ping ones that have a continuous trans- mission, such as a weather channel. You can lock out up to all 200 channels while scanning, or skip up to 20 frequen- cies during a band or direct search.

To skip a channel/frequency while scan- ning or searching, press S/S-LOCKOUTwhen the scanner stops on it.

Notes:

•If you skip more than 20 search fre- quencies, each new frequency replaces an earlier one, starting from the first stored frequency.

•You can manually select skipped frequencies after you press HOLD to stop a search. The scanner displays L/O when you select a skipped fre- quency. See “Manually Selecting a Channel” on Page 18).

Removing Skip from

Frequencies

To remove the skip from a frequency while searching, press HOLD to stop the search, press ▲ or ▼ to select the skipped frequency, then repeatedly press S/S until L/O disappears.

To remove the skip from all frequencies at once while searching, hold down S/S- LOCKOUT until the scanner beeps twice.

20-422 specifications

The Radio Shack 20-422 is a versatile and compact handheld scanner that has garnered recognition among hobbyists and communication enthusiasts alike. This model is designed to provide users with an easy-to-use interface and advanced scanning capabilities, making it a popular choice for those looking to stay connected with public safety, aviation, and other radio communications.

With coverage from 30 MHz to 900 MHz, it allows users to access a diverse array of radio signals, including AM, FM, and analog transmissions. This broad frequency range ensures that operators can track vital communications from police departments, fire services, and emergency medical teams.

In addition to its expansive scanning capabilities, the 20-422 is equipped with 200 programmable channels. This enables users to store their favorite frequencies for quick access, thus enhancing the overall user experience. The unit is also compatible with commonly used trunking systems, which allows users to monitor communications from trunked radio systems, widely employed by public safety organizations.

The Radio Shack 20-422 comes with a customizable priority scanning feature, which allows users to set specific channels to scan more frequently. This ensures that important communications are not missed, adding a level of efficiency to the scanning process. Moreover, the scanner features a large LCD display that provides users with clear visibility of the frequency and other important information.

From a technological standpoint, the 20-422 is equipped with automatic frequency identification, which simplifies the process of discovering new radio signals. The built-in alert system notifies users when specific transmissions are detected, adding convenience to the scanning routine.

The ergonomic design of the Radio Shack 20-422 enhances ease of use, equipped with a comfortable grip and well-placed buttons for intuitive operation. The scanner is powered by a reliable battery system, ensuring long hours of dynamic scanning capabilities, whether you are in a stationary location or on the move.

In summary, the Radio Shack 20-422 stands out as a powerful tool for anyone interested in radio communications. With its extensive frequency coverage, programmable channels, and user-friendly design, this handheld scanner is perfect for hobbyists, emergency responders, and anyone else looking to stay connected with their community.
