2 FEA TURES Your new Rad ioShack PR O-2050 VHF/UHF/A ir/ 800MHz 300 -Channel TrunkTracker Home Scann er is one of a new generat ion of scanne rs de- signed to track Motorola Ty pe I, Type II (such.
3 Scan Delay — delays scan ning for about 2 seconds before mov ing to an- other channel in convent ional mode, so you can hear mo re replies that are made on the same channel. In trunk tracking mo de, it delays f or about 5 seconds before mov ing to another ID.
4 Your PRO- 2050 scanne r can receive all of these bands: Note: See “S p ecifications” on Page 51 for more information about the scan- ner’s frequency steps. FCC NO TICE Your scanne r might c ause T V or radi o interference even when it is op erating properly.
5 SCANNING L EGALL Y Scanning is a fun and interesting hob- by. Y ou can hear police and f ire de- partments, am bulance s ervices, government ag encies, private compa- nies, amat eur radio services , aircraft, and mi litary operation s. It is legal to listen to almos t every transmission your scanner can rec eive.

8 PREPARA TION This scanner is designed prim arily for use in the home as a base st ation. You can place it on a desk, s helf, or tab l e. Your scann er’s fr ont feet fold u p or down. Adjust the m to give you the best view of the display. Your scanne r’s displ ay is protected during shipment by a piece of blue fi lm .
9 • T he ant enna shou ld be as high as possible on the v ehicle or b uilding. • T he ante nna and its cabl e should be as far as pos sible from sourc es of electrical noise (appl iances, other radios , etc.). • T he anten na should be vert ical for the be st performance.
10 Cautions: • The supplied AC adapt er supplies 12 vo lt s DC power and delivers 500 millia mps. Its center tip is set to positive, and its plug properly fits the scanner ’s DC 12V jack. Using an adapte r that does not meet these spec ifications could damage t he scanner or the adapter .
11 Note: Connecting an external speaker disconnects the scanner’s int ernal speaker. CONNECTING AN EARPHONE/ HEADPHONES For private listening, you can c onnect an earphone or hea dphones wit h a 1 / 8 - inch plug (such as Cat. No. 33-175 or 20-210) to the jack on the front of the scanner.
12 UNDERSTANDING Y OUR S CANNER Once you understand a few s imple terms we use in thi s manual and familiarize yourself with your scanner’s features, you can p ut the sc anner to work for you. You simply det ermine the ty pe of comm unications you want to receive, then s et the scanner to sca n them.
13 SCAN Scans through the stored channels. MANUAL Stops scanni ng and let s you d irectl y e nter a channe l number o r frequenc y. TRUNK Switches between conven tional a nd trunk t r acki ng modes. SVC ( ser vi ce ) Selects a service bank. PRIORITY/SPEED S ets and turns on and off the prio rity feature; turns the HyperSearch mode on and off.
14 HOLD/ s Holds on the c u r ren t I D in t he trunk tracking mode; sets the search di rection and ho lds the fre quency search. DA T A Turns the data signal skip featu r e on or off or checks the current trunking bank in t h e trunk tracking mode.

21 SPEC IAL FE ATURES DELAY Many agen cies use a two-way radio system t hat might have a period of 2 or more seconds between a que ry and a reply. T o keep from m issing a reply, you can program a 2-second del ay into a ny channe l or frequenc y.
22 LOCKING OUT CHANNELS AND FREQUENCIES You can scan ex isting cha nnels or search frequ encies faster by locking out channels or freq uencies that have a continuou s transmission, such as a weather cha nnel. Note: If you ju st want to skip over a lengthy transmiss ion ( such as a mo- dem sig nal), see “Skipping Dat a Sig- nals” on Page 23.

25 T YPES OF T R UNKING SYS TEMS Your trunk trac king scanner c an m oni - to r two bas ic types of systems — Type I and Ty pe II . Instead of selecting a specific frequ ency to transm it on, a trunked syst em choos es one of sev er- al frequencies in a 2-way radio user’s talk group when that user presses PTT (push t o talk).

28 Note: T o s ee the bank current ly in use for about 5 seconds, press DA T A while in the trunk tracking mode. 3. T o return to convent ional scan- ning, press TRUNK aga in.
29 To lock out an ID, pres s L/O when the ID appears. The ID is locked out, and the n ext ac- tive ID a ppears. Unlock ing a Sing le ID 1. Hold down L/O until you hea r two short beeps. 2. Repeatedly press t o r s to select t h e I D y o u w a nt t o unl o ck .
30 Moni t o ri ng I Ds You can use your s canne r’s displ ay to monitor the frequenci es in a trunked system f or ac tivity. You can not he ar conversations in t h is mode , but this is an excellent way to determ ine which talk group s are the most ac tive.
31 SCAN LISTS When y ou program trunk ed freque n- cies into a bank (see “Programming Trunked Frequenc ies” on P age 26), your scanner se ts up 5 scan lists into which y ou can s t ore y our favorite IDs.
32 Sto ring I D s int o Scan Li sts Wh ile Sear chi ng Follow these s teps to s elect a scan list location and store an ID during a search. 1. When yo ur scanner sto ps on an ID you want to store, press PRI- ORITY . The c urrently selected scan list m emory location flashes .
33 To remove a scan list from active scanning, u se the n umber k eys to e n- ter the s can list’s number. The scan list indicator turns off, and the IDs in that list are not scanned. Note: You cannot rem ove a ll the scan li sts . One s can list m ust always b e ac- ti ve .

45 FREQUENCY CON V ERSION The tuning location of a station can be e xpressed in frequency (kHz or M Hz) or in wavelength (meters). The foll owing information can help you make the necessary conversions. 1 MHz (m illi on) = 1,000 kHz (thousand ) To convert MHz to kHz, multiply the number of megahert z by 1,000: 9.
