No. 20-524  \nPRO-94 1000-Channel Handheld Trunking Scanner  \nPlease read before using this equipment.  \nYour RadioShack PRO-94 1000-Channel Handheld Trunking Scanner is one of a new generation of scanners designed to track Motorola Type I, Type II, hybrid analog systems,(such as Smartnet and Privacy Plus) plus GE/Ericsson EDACS. Those systems are extensively used in many 800 MHz, 900 MHz, and UHF communication systems.  \nTrunking 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 (on a different frequency called a data channel) a code that uniquely identifies that transmission.  \nSince 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 PRO-94 lets you select and monitor the data channel frequency sent with a 2-way radio transmission, so you can hear the call and response for that user and more easily“follow” the conversation.  \nThe scanner also lets you scan conventional transmissions, and it is preprogrammed with service 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.  \nThis scanner gives you direct access to over 37,000 exciting frequencies, including police and fire departments, ambulance services, and amateur radio services, and you can change your selection at any time.  \nYour scanner also has these special features:  \nTriple-Conversion Circuitry —virtually eliminates any interference from IF (intermediate frequency) images, so you hear only the selected frequency.  \n© 1999 Tandy Corporation.  \nAll Rights Reserved.  \nRadioShack and Adaptaplug are registered trademarks used by Tandy Corporation.  \nHypersearch and Hyperscan are trademarks used by Tandy Corporation.  \n2  \n[20-524.fm](20-524.fm) Page 3 Tuesday, August 31, 1999 3:55 PM  \n20 Channel-Storage Banks —you can store up to 50 channels in each of 10 different banks, in two separate groups, for a total of 1000 channels, so you can more easily identify calls.  \nFive Scan Lists —you can store up to 50 trunking talk group IDs in each trunk scanning bank.  \nNWR-SAME Circuitry — lets you listen to coded weather emergency information using Specific Area Message Encoding.  \nTwo-Second Scan Delay —delays scanning for about 2 seconds before moving to another channel, so you can hear more replies that are made on the same channel.  \nLock-Out Function —lets you set your scanner to skip over specified channels or frequencies when scanning or searching, and skip over talk group IDs when tracking trunked systems.  \nPriority Channels — lets you program one channel in each bank (20 in all) and then have the scanner check that channel every 2 seconds while it scans the bank, so you don't miss transmissions on those channels.  \nFive Service Banks —frequencies are preset in separate police (fire/emergency), aircraft, ham, marine, and weather banks, to make it easy to locate specific types of calls.  \nHypersearch ™ — lets you set the scanner to search at up to 300 steps per second in frequency bands with 5 kHz steps, compared to the normal search speed of 100 steps per second.  \nHyperscan ™ — the scanner automatically scans up to 50 channels per second to help you quickly find interesting broadcasts.  \nKey Lock — lets you lock the scanner's keys to help prevent accidental changes to the scanner's programming.  \nData Signal Skip — lets you set the scanner to skip non-modulated or data signals (such as fax or modem transmissions) during searches.
