Features Your RadioShack Handheld Scanner is one of a new generation of scanners designed to track Motorola® Type I and II (such as Smartnet® and Privacy Plus®) and hybrid analog trunking systems, and GE/Ericsson (EDACS®) type systems, which are extensively used in many communication systems. Trunking communications systems let a large group of 2-way radio users (or even different groups of 2-way radio users) efficiently use a set of frequencies. Instead of selecting a specific frequency for a transmission, the user simply selects a talk group. The trunking system automatically transmits the call on the first available frequency, and also sends a code that uniquely identifies that transmission. Since the trunking system might send a call and its response on different frequencies, it is difficult to listen to trunked communications using a regular scanner. The scanner monitors the data sent with a 2-way radio transmission, so you can hear the call and response for that user and more easily “follow” the conversation. The scanner also lets you scan conventional transmissions, and is preprogrammed with service search banks for convenience. By pressing a single button, you can quickly search those frequencies most commonly used by public service and other agencies without tedious and complicated programming. This scanner gives you direct access to over 59,000 frequencies including those used by police and fire departments, ambulance services, government agencies, air, and amateur radio services. Your scanner includes these features: 20-523 Owner’s Manual Page 2 Simultaneous Trunking Operation – tracks two trunking systems (Motorola and EDACS) and conventional systems at the same time. 10 Channel-Storage Banks – let you store 30 channels in each bank (300 channels) to group channels so calls are easier to identify. 10 ID-Storage banks – let you store 1,000 IDs in 10 ID banks, each ID bank has 5 sub-ID banks, 20 IDs are programmed in each sub-ID bank and let you easy identify the ID code. 12-Character, 4-Line, Dot-Matrix Display – shows you detailed operating information and lets you easily program the scanner. Weather Alert – automatically sounds the alarm tone to advise of hazardous weather conditions when it detects the alert signal on the local National Oceanic and Atmospheric Administration (NOAA) weather channel during priority operation. Digital Weather Alert – displays the weather event text with three alert levels so you can see and hear the reason for the alert. Preprogrammed Frequency Ranges – lets you search for transmissions within preset frequency ranges or within ranges you set, to reduce search time and select interesting frequencies more quickly. Data Cloning – lets you transfer the programmed data to another PRO-93 or PRO-2053 scanner. You can also upload or download the programmed data to or from a PC using an optional interface kit. Triple Conversion Superheterodyne Receiver – virtually eliminates any interference from intermediate frequency (IF) images, so you hear only the frequency you select. Hyperscan TM and Hypersearch TM – the scanner scans and searches at up to 60 channels per second, to help you quickly find interesting transmissions. Scan Delay – delays scanning for about 2 seconds before moving to another channel in conventional mode, so you can hear more replies that are made on the same channel. Priority Channel – you can set the scanner to check one channel every 2 seconds so you do not miss important calls. Signal Attenuation (Attenuate) – lets you program in your scanner to reduce the scanner’s sensitivity to strong local signals, to reduce interference or noise caused by these signals. Text Input – lets you input a text label for each channel, talk group ID, bank, or other memory location so you can easily know about the transmission you are hearing. Lock Out Function – lets you set your scanner to skip over specified channels or frequencies when scanning or searching, and skip over IDs when tracking trunked systems. 20-523 Owner’s Manual Page 3 Key Lock – lets you lock the scanner’s keys to help prevent accidentally changing the scanner’s programming. Flexible Antenna with BNC Connector – provides excellent reception and is designed to help prevent antenna breakage. Memory Backup – keeps the frequencies stored in memory for an extended time even without internal batteries. Three Power Options – let you power the scanner with internal batteries (non-rechargeable batteries or rechargeable batteries). You can also use an AC adapter (not supplied) or power the scanner in a vehicle using a DC adapter (not supplied). Supplied Police Call Trunking Guide – provides a quick reference to public safety trunking radio systems in the United States. Your scanner can receive these frequencies: . 25—54 MHz . 108—136.9875 MHz . 137—174 MHz . 216—225 MHz . 406—512 MHz . 806—823.9875 MHz . 849—868.9875 MHz . 894—960 MHz . 1240—1300 MHz This Owner’s Manual also includes the section “A General Guide to Scanning” on Page XX to help you target frequency ranges in your service area so you can search for a wide variety of transmissions. FCC NOTICE Your scanner might cause TV or radio interference even when it is operating properly. To determine whether your scanner is causing the interference, turn off your scanner. If the interference goes away, your scanner is causing the interference. Try the following methods to eliminate the interference. . Move your scanner away from the TV…

The frequencies in question are deleted from the ROM during manufacture, and cannot be restored through any readily available process or component such as: installation of cuts, jumper wires, resistors, diodes, or plug-in IC’s; deletion of such items; or reprogramming via access codes or external devices such as a personal computer. The receiver is incapable of converting digital cellular transmissions to analog voice audio. Assessing the vulnerability of the receiver to possible modification The receive has the possibility of reducing the threshold value to discern transmissions from the Cellular Radiotelephone Service by making modification such as adding jumper wire to the RF band pass filters. Design features that prevent modification of the receiver to receive Cellular Service The scanning receiver is designed to prevent any attempt for the user to modify the receiver to receive transmissions from the Cellular Radiotelephone Service by using epoxy to cover the required parts of the RF circuitry including control circuits and band pass filters. Testing method used to determine compliance with the 38 dB rejection ratio Testing method The 12 dB SINAD measurement method in the Cellular Radiotelephone Service used for frequencies that the receiver tunes and the signal rejection ratio gained by the measurement.
