By pressing a one touch search key, 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 22,000 exciting frequencies, including those used by police and fire departments, ambulance services, aircraft, and amateur radio services, and you can change your selection at any time. Your scanner also has these special features: Spectrum Sweeper – a powerful new tool for you to rapidly detect, monitor and store frequencies for Page 2
0712 Owner’s Manual nearby radio transmissions. One Touch Search Banks — let you search preset frequencies in separate marine, fire/police, aircraft, ham, and weather banks, to make it easy to locate specific types of calls. Display Backlight — makes the scanner easy to read in low-light situations. Lockout Function — lets you set your scanner to skip over specified channels or frequencies when scanning or searching. Ten Channel-Storage Banks — you can store 20 channels in each bank (200 total channels), letting you group channels so you can more easily identify calls. Tune — lets you tune for new and unlisted frequencies starting from a specified frequency. SAME/FIPS Weather Alert — displays the weather event for the specific cities or counties you choose so you can hear the alert tone. Memory Backup — keeps the frequencies stored in memory for an extended time during a power loss. Scan Delay — delays scanning for about 2 seconds before moving to another channel, so you can hear more replies that are transmitted on the same channel. Priority Channel — lets you program a channel as the priority channel. As the scanner scans, it checks the priority channel every 2 seconds so you do not miss transmissions on that channel. Data Cloning — lets you transfer the programmed data to another 0712 scanner. Liquid-Crystal Display — makes it easy to view and change programming information. Supplied Telescoping Antenna — provides good reception of strong local signals.

These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: • Reorient or relocate the receiving antenna. • Increase the separation between the equipment and receiver. • Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. SCANNING LEGALLY Your scanner covers frequencies used by many different groups including police and fire departments, ambulance services, government agencies, private companies, amateur radio services, military operations, pager services, and wireline (telephone and telegraph) service providers. It is legal to listen to almost every transmission your scanner can receive. However, there are some transmissions you should never intentionally listen to. These include: • Telephone conversations (cellular, cordless, or other private means of telephone signal transmission) • Pager transmissions Page 4
0712 Owner’s Manual • Any scrambled or encrypted transmissions According to the Electronic Communications Privacy Act (ECPA), you are subject to fines and possible imprisonment for intentionally listening to, using, or divulging the contents of such a transmission unless you have the consent of a party to the communication (unless such activity is otherwise illegal). This scanner has been designed to prevent reception of illegal transmissions. This is done to comply with the legal requirement that scanners be manufactured so as to not be easily modifiable to pick up those transmissions. Do not open your scanner’s case to make any modifications that could allow it to pick up transmissions that are illegal to monitor. Doing so could subject you to legal penalties. In some areas, mobile use of this scanner is unlawful or requires a permit. Check the laws in your area. It is also illegal in many areas to interfere with the duties of public safety officials by traveling to the scene of an incident without authorization. We encourage responsible, safe and legal scanner use. PREPARATION POWER SOURCES USING AC POWER You can power the scanner using a supplied AC adaptor. Cautions: ! You must use a Class 2 power source that supplies 9V DC and delivers at least 300 mA. Its center tip must be set to positive and its plug must fit the scanner's PWR DC 9V jack. Using an adaptor that does not meet these specifications could damage the scanner or the adapter. • Always connect the AC adaptor to the scanner before you connect it to AC power. When you finish, disconnect the adaptor from AC power before you disconnect it from the scanner. • The correct orientation for the enclosed power adaptor is in a vertical or floor-mount position. To power the scanner using an AC adaptor, connect the plug into the scanner’s DC 9V jack. Then connect the AC adaptor to a standard AC outlet. WARNING: To prevent electric shock, do not use the AC adaptor’s polarized plug with an extension cord, receptacle, or other outlet unless you can fully insert the blades to prevent blade exposure. Page 5
0712 Owner’s Manual USING VEHICLE BATTERY POWER You can power the scanner from a vehicle’s 12V power source (such as cigarette-lighter socket) using a 9V, 400-mA DC adaptor with 4.75mm outer/1.7mm inner plug. Its center tip must be set to positive and its plug must fit the scanner's DC 9V jack. Using an adapter that does not meet these specifications could damage the scanner or the adaptor. Cautions: Always connect the DC adapter to the scanner before you connect it to the power source. When you finish, disconnect the adapter from the power source before you disconnect it from the scanner. To power the scanner using a DC adaptor, connect the plug into the scanner’s DC 9V jack. Plug the other end of the DC adaptor into your vehicle’s cigarette-lighter socket. Note: If you use a cigarette-lighter power cable and your vehicle’s engine is running, you might hear electrical noise from the engine while scanning. This is normal. CONNECTING THE SUPPLIED ANTENNA You must install an antenna before you can operate the scanner. The supplied telescoping antenna helps your scanner receive strong local signals. To install the antenna, thread it clockwise into the hole on top of the scanner. The scanner’s sensitivity depends on its location and the antenna’s length. For the best reception of the transmissions you want to hear, adjust the antenna’s length according to the chart below. Frequency Antenna Length 29-174 MHz Extend fully 380-512 MHz Extend 2 segments Connecting an Outdoor Antenna The antenna connector on your scanner makes it easy to use the scanner with a variety of antennas, such as an external mobile antenna or outdoor base station antenna. Always use 50 Ohm coaxial cable, such as RG-58 or RG-8, to connect an outdoor antenna. For lengths Page 6
0712 Owner’s Manual over 50 feet, use RG-8 low-loss dielectric coaxial cable. If the antenna cable’s connector does not have a BNC connector, you will also need a BNC adapter. Follow the installation instructions supplied with the antenna, route the antenna cable to the scanner, then connect it to the antenna jack. Warning: Use extreme caution when you installing or removing an outdoor antenna. If the antenna starts to fall, let it go! It could contact overhead power lines. If the antenna touches a power line, contact with the antenna, mast, cable, or guy wires can cause electrocution and death. Call the power company to remove the antenna. DO NOT attempt to do so yourself. CONNECTING AN EARPHONE/HEADPHONES For private listening, you can plug an 1/8 -inch (3.5-mm) mini-plug earphone or headphones (not supplied), into the (headphone symbol mark) jack on the back of the scanner. This automatically disconnects the internal speaker. Listening Safely To protect your hearing, follow these guidelines when you use an earphone or headphones. • Set the volume to the lowest setting before you begin listening. After you begin listening, adjust the volume to a comfortable level. • Do not listen at extremely high volume levels. Extended high-volume listening can lead to permanent hearing loss. • Once you set the volume, do not increase it. Over time, your ears adapt to the volume level, so a volume level that does not cause discomfort might still damage your hearing. Traffic Safety Do not wear an earphone or headphones with your scanner when operating a motor vehicle or riding a bicycle in or near traffic. Doing so can create a traffic hazard and could be illegal in some areas. If you use an earphone or headphones with your scanner while riding a bicycle, be very careful. Do not listen to a continuous broadcast. Even though some earphones and headphones let you hear some outside sounds when you listen at normal levels, they still can present a traffic hazard. CONNECTING AN EXTENSION SPEAKER Page 7
0712 Owner’s Manual In a noisy area, an extension speaker (not supplied) might provide more comfortable listening. Plug the speaker cable’s 1/8 inch (3.5 mm) mini-plug into your scanner’s (headphone symbol mark) jack. ABOUT YOUR SCANNER Once you understand a few simple terms used in this manual and familiarize yourself with your scanner’s features, you can put the scanner to work for you. You simply determine the type of communications you want to receive, then set the scanner to scan them. A frequency is the receiving signal location (expressed in kHz or MHz). To find active frequencies, you can use the search or tune function. You can also search the One Touch Search Banks, which are preset groups of frequencies categorized by type of service. When you find a frequency, you can store it into a programmable memory location called a channel, which is grouped with other channels in a channel-storage bank. You can then scan the channel-storage banks to see if there is activity on the frequencies stored there. Each time the scanner finds an active frequency, it stays on that channel until the transmission ends. ABOUT THE KEYPAD Here is a brief overview of your scanner’s keys and their functions.

UNDERSTANDING BANKS Channel Storage Banks A bank is a storage area for a group of channels. Channels are storage areas for frequencies. Whereas a channel can only contain one frequency, a bank can hold numerous channels. To make it easier to identify and select the channels you want to listen to, your scanner divides the channels into 10 banks (1 to 10) of 20 channels each, a total of 200 channels. You can use each channel-storage bank to group frequencies, such as those used by the police department, fire department, ambulance services, or aircraft. Page 10
0712 Owner’s Manual For example, a police department might use four frequencies, one for each side of town. You could program the police frequencies starting with Channel 1 (the first channel in bank 1) and program the fire department frequencies starting with Channel 21 (the first channel in bank 2). One Touch Banks The scanner is preprogrammed with the frequencies allocated by marine, fire/police, aircraft, ham radio, and weather services. This is handy for quickly finding active frequencies instead of searching through an entire band (see “Searching the One Touch Banks” on Page XX). Note: The frequencies in the scanner’s service banks are preset. You cannot change them. Fire/Police Group Frequency Range (MHz) Step (kHz) 1 33.420–33.760 20 33.960 – 37.180 – 37.320 – 37.380 – 37.440–39.980 20 42.020–42.940 20 44.620–45.860 40 45.880 – 45.900 – 45.940–46.060 40 46.080–46.500 20 2 153.770–154.130 60 154.145–154.445 15 154.650–154.950 15 155.010–155.370 60 155.415–155.700 15 155.730–156.210 60 158.730–159.210 60 166.250 – 3 453.0375–453.9625 12.5 458.0375–458.9625 12.5 Page 11

To change the channel manually, press ^ or v. To search through the weather bank again, press PSE. MAN disappears and SRCH appears. To change the searching direction, press ^ or v. SAME Standby Mode The National Weather Service precedes each weather alert with a digitally encoded SAME (Specific Area Message Encoding) signal, then a 1050 Hz tone. The SAME signal includes a FIPS (Federal Information Processing Standard) area code, and an event code that corresponds with the type of alert being sent. You can configure your scanner to operate in SAME Standby mode, where it monitors a selected weather radio station for SAME alerts for areas you specify. You can program your scanner with up to 7 FIPS codes for the areas you desire. The National Weather Service maintains a current list of FIPS codes at http://www.nws.noaa.gov/nwr/. To configure your scanner for SAME Standby mode, follow these steps: 1. Press WX. 2. Press PGM to access the FIPS code entry table. 3. Use ^ or v keys to select the desired FIPS code storage location. 4. Use the number keys to enter the desired FIPS code, and then press ENT to store the code. Repeat this process for all the FIPS codes that you wish to store. 5. Press L/OUT to lock out or enable specific FIPS entries. 6. Press WX to exit the FIPS code entry table. Notes: • Your scanner can also detect the 1050 Hz weather alert tone when a weather channel is set as the priority channel and weather priority operation is enabled (see “Priority”). In this mode all alerts are received. FIPS settings are ignored. Page 20
0712 Owner’s Manual • The scanner sounds an alert or beep when it receives the SAME code. If you do not stop the alert (or beep) for five minutes, the alert stops and the scanner beeps every ten seconds. If the scanner receives a new message after five minutes, it sounds the alert or beep. To stop the sound and ready the scanner to receive a new alert signal before the five minute time out, press any key. 7. Press PRI/ALERT to initiate SAME standby. The scanner will monitor the all weather radio station for alerts with FIPS codes that match the codes you entered in the FIPS entry table. To exit SAME standby, press PRI/ALERT again. Skywarn Many areas of the country have amateur radio repeaters that have been designated as “Skywarn” repeaters. During times of severe weather, these repeaters are used to relay reports of severe weather directly to meteorologists at a local National Weather Service (NWS) forecast office. Using the Skywarn feature in your scanner, you can easily jump to Skywarn repeater frequencies and monitor these reports, in many cases hearing about severe weather in your area instantly as it occurs. This function lets you quickly move to the skywarn channels (Channel 200) from any mode by pressing and holding WX about 2 seconds. The scanner displays SKYWARN symbol. Note: To activate this function, you must program your desired Skywarn frequency into the Skywarn channel. Spectrum Sweeper Your scanner’s Spectrum Sweeper feature provides a powerful new tool for you to rapidly detect, monitor and store frequencies for nearby radio transmissions. The Spectrum Sweeper feature is similar in functionality to portable frequency counters that cost much more than your scanner, but provides many advantages over typical portable frequency counters. For example: The Spectrum Sweeper allows you to sweep the entire range of your scanner’s design frequencies, or you can specify those frequency ranges that you wish to sweep and exclude ranges that you do not want to sweep. This allows you to omit frequency ranges with constant strong frequency activity, such as those with paging or broadcast transmitters. Many portable frequency counters will remain locked to a nearby constant signal, such as a paging or broadcast transmitter, and will not function properly until you have left the vicinity of the transmitter. The Spectrum Sweeper feature is more sensitive than portable frequency counters and will detect Page 21
0712 Owner’s Manual transmissions at a greater distance. You can activate the Attenuator to reduce the sensitivity if desired. Once an active frequency is found, the transmission is played through your scanner’s speaker, and you can quickly store it in any of your scanner’s memory locations. Using Spectrum Sweeper The Spectrum Sweeper can be set to watch for activity on all band, Police/Fire, Aircraft, or Ham frequencies. When the scanner is in manual, scan or tune mode, press SS to watch for activity on all band. When the scanner is in Police/Fire search band, press SS to watch for activity on Police/Fire band. When the scanner is in Aircraft band, press SS to watch for activity on Aircraft band. When the scanner is in Ham band, press SS to watch for activity on Ham band. You can also turn on/off frequency sub-bands using the corresponding number keys while Spectrum Sweeper is active. Note: Priority mode is not available while using the Spectrum Sweeper. SPECIAL FEATURES DELAY Many agencies use a two-way radio system that has a period of several seconds between a query and a reply. To avoid missing a reply, you can program a 2-second delay into any channel or frequency. When your scanner stops on a channel or frequency with a programmed delay, DLY appears and the scanner continues to monitor that channel or frequency for 2 seconds after the transmission stops before resuming scanning, searching, tuning, or spectrum sweeping. You can program a 2-second delay in any of these ways: • If the scanner is scanning and stops on an active channel, quickly press DELAY/• before it resumes scanning. • If the desired channel is not selected, manually select the channel, then press DELAY/• . • If the scanner is searching, tuning, or spectrum sweeping, press DELAY/• . DLY appears and the scanner automatically adds a 2-second delay to every transmission it stops on in that band. To turn off the 2-second delay in a channel or for all frequency, press DELAY /• while the scanner is monitoring that channel or frequency. DLY disappears. Page 22
0712 Owner’s Manual LOCKING OUT CHANNELS OR FREQUENCIES You can increase the effective scanning or search speed by locking out individual channels or frequencies that have a continuous transmission, such as a weather channel (see “National Weather Frequencies” on Page XX) or a birdie frequency (see “Birdie Frequencies” on Page XX). Locking Out Channels To lock out a channel during scanning, press L/O/L/O RVW when the scanner stops on the channel. To manually lock out a channel, select the channel then press L/O/L/O RVW until L/O appears. To remove the lockout from a channel, manually select that channel again, then press L/O/L/O RVW until L/O disappears. Notes: • Your scanner automatically locks out empty channels. • You can still manually select locked-out channels. Locking Out Marine and WX Channels To lock out a Marine or WX channel during searching, press L/O when the scanner stops on the channel. To manually lock out a Marine or WX channel, select the channel then press L/OUT. To remove the lockout from a Marine or WX channel, manually select that channel again, then press L/O until L/O disappears. Locking Out Frequencies To lock out a frequency during a one touch search or spectrum sweeper, press L/O/L/O RVW when the scanner stops on that frequency. The scanner locks out the frequency then continues searching/sweeping. Notes: • You can lock out as many as 50 frequencies during a search (or spectrum sweep). If you try to lock out Page 23
0712 Owner’s Manual more, FLo -FULL appears (see “Reviewing Locked-Out Frequencies” and “Removing Lockouts From All Frequencies”). • The scanner uses same Lockout List between one touch search bank and spectrum sweeper. (ex.: the scanner uses same lock out list between aircraft search band and aircraft spectrum sweeper band.) Reviewing Locked-Out Frequencies To review the frequencies you locked out, hold down L/O/L/O RVW for about 2 seconds during a search or spectrum sweeper, then repeatedly press ^ or v. L-r (Lockout Review) appears and the scanner displays all locked out frequencies as you press ^ or v, or, EMPty appears when the search bank has no locked out frequencies. When you reach the highest locked-out frequency, the scanner beeps twice and returns to the lowest locked-out frequency. Removing Lockouts Form All Frequencies in a One Touch Search Bank Note: These steps do not clear any lockouts in the marine and weather bank. 1. Hold down L/O/L/O RVW for about 2 seconds during a desired search band. L-r appears. 2. While holding down TUNE/CLEAR, press L/O to clear the lockout. FLo ALL-CL appears about 2 seconds. After 2 seconds, YES ---Ent and No ---CLEAr appears alternately. 3. Press ENT. L-r EMPty appears. The scanner clears any lockouts from all frequencies in a one touch bank. Or, if you do not want to clear the lockouts, press TUNE/CLEAR. USING PRIORITY The priority feature lets you scan through channels and still not miss important or interesting calls on a frequency you select. You can program one frequency into the priority channel. As the scanner scans, if the priority feature is turned on, the scanner checks the priority channel for activity every 2 seconds. 1. Press PGM, then press PRI/ALERT. PCH and 000.0000 or the previously-stored frequency appear. 2. Enter the frequency you want to enter into the priority channel, then press ENT. The display flashes twice. To program a weather channel as the priority channel: Page 24
0712 Owner’s Manual 1. Press WX. 2. Select the weather channel you want to program as the priority channel. 3. Press and hold ENT then PRI. P ChAnnEL is displayed momentarily. Aftter P ChAnnEL appears, PCH flashes and 000.0000 or the previously-stored frequency appears. 4. Press ENT to store the priority channel and display blinks two times. Press CLEAR to cancel. To turn on the priority feature, press PRI/ALERT during scanning or searching. PRI appears. The scanner checks the priority channel every 2 seconds and stays on the channel if there is activity. PCH and the frequency appear whenever the scanner is set to the priority channel. To turn off the priority feature, press PRI/ALERT. PRI disappears. Note: If you program a weather frequency into the priority channel and the scanner detects a WX alert tone on that frequency (see “WX Alert” on Page XX), the scanner sounds the alert tone and ALErt flashes. Press any key to turn off the alarm. TURNING THE KEY TONE ON AND OFF The scanner is preset to sound a tone each time you press one of its keys. You can turn the key tone off or on. 1. If the scanner is on, slide POWER to off. 2. Slide POWER to turn on the scanner. Welcome message appears.. 3. While Welcome message appears, press 1 to turn on the key tone or 2 to turn it off.. Cloning the Programmed Data You can transfer the programmed data to and from another 0712 scanner using an optional connecting cable with 3.5mm phone plugs on both ends (not supplied). 1. Turn on both scanner. 2. Connect the connecting cable to each scanner’s PC/IF jack. CLOnE and UP to SEnd appears. Page 25
0712 Owner’s Manual 3. Press ^ at the host scanner. 4. SEndInG appears at the host scanner. The scanner sends the data. To exit the clone mode, remove the cable. CLOnE and Error may alternately appear when the scanner receives data from a scanner other than a 0712. If this happens when the scanner receives data from another 0712, turn off the scanner and then turn it on again. INITIALIZING THE SCANNER If the scanner’s display locks up or does not work properly after you connect a power source, you might need to initialize the scanner. Important: This procedure clears all information you stored in the scanner’s memory. Initialize the scanner only when you are sure the scanner is not working properly. 1. Turn off the scanner, then turn it on again. WELCOME SCAnnInG rECEIVEr appears. 2. Press 0 while welcome message appears. Then press 1. InItIAL appears about 2 seconds. After 2 seconds, YES ---Ent and No ---CLEAr appears alternately. 3. Press ENT. WAIt appears for about 2 seconds. Note: Do not turn off the scanner until the initialization is complete. When the initialization is complete, 1CH 000.0000 appears on the display. A GENERAL GUIDE TO SCANNING Birdie Frequencies Every scanner has birdie frequencies. Birdies are signals created inside the scanner’s receiver. These operating frequencies might interfere with transmissions on the same frequencies. If you program one of these frequencies, you hear only noise on that frequency. If the interference is not severe, you might be able to turn SQUELCH clockwise to cut out the birdie. Page 26
0712 Owner’s Manual To find the birdies in your individual scanner, begin by disconnecting the antenna and moving it away from the scanner. Make sure that no other nearby radio or TV sets are turned on near the scanner. Use the search function and search every frequency range from its lowest frequency to the highest. Occasionally, the searching will stop as if it had found a signal, often without any sound. That is a birdie. Make a list of all the birdies in your scanner for future reference. FREQUENCY CONVERSION The tuning location of a station can be expressed in frequency (kHz or MHz) or in wavelength (meters). The following information can help you make the necessary conversions. 1 MHz (million) = 1,000 kHz (thousand) • To convert MHz to kHz, multiply the number of megahertz by 1,000: 30.62 (MHz) x 1000 = 30,620 kHz • To convert from kHz to MHz, divide the number of kilohertz by 1,000: 127,800 (kHz) / 1000 = 127.8 MHz • To convert MHz to meters, divide 300 by the number of megahertz: 300 / 50 MHz = 6 meters FAQs (Frequently Asked Questions) The scanner is not working at all. What’s wrong? • The AC or DC adaptor might not be connected. Be sure the adaptor’s barrel plug is fully inserted into the DC 9V jack. The center tip of the adaptor’s barrel plug must be set to positive. The scanner does not receive any stations or reception is poor. What’s wrong? • The scanner might need to be initialized. Turn the scanner off then on again, or initialize the scanner (see “Initializing the Scanner”). The scanner is on but does not scan. What’s wrong? • The squelch might not be adjusted correctly. Turn SQ clockwise. There might only be one channel or no channels stored in the scanner. Store frequencies into more than one channel. Page 27
0712 Owner’s Manual While scanning, the scanner locks on frequencies that have an unclear transmission. What’s wrong? • Some frequencies programmed into the scanner might be the same as “birdie” frequencies. Avoid programming “Birdie Frequencies” or only listen to them manually. CARE Keep the scanner dry; if it gets wet, wipe it dry immediately. Use and store the scanner only in normal temperature environments. Handle the scanner carefully; do not drop it. Keep the scanner away from dust and dirt, and wipe it with a damp cloth occasionally to keep it looking new. IN CASE OF FAULT Where a fault arises, contact your supplier. However, before you do so check that the fault was not caused by an operational error. Carefully reread the relevant section in the instructions.
