11 Using Standard AC Power To power the scanner from an AC out- let, you need an AC adapter (not sup- plied) with a 5.5 mm outer diameter/ 2.1 mm inner diameter tip. Cautions: You must use a Class 2 power source that sup- plies 12V DC and deliv- ers at least 500 mA. Its center tip must be set to positive and its plug must fit the scanners DC 13.8V jack. Using an adapter that does not meet these specifica- tions could damage the scanner or the adapter. • Always connect the AC adapter to the scanner before you connect it to AC power. When you finish, dis- connect the adapter from AC pow- er before you disconnect it from the scanner. 1. Connect the adapters 5.5 mm outer diameter/2.1 mm inner diameter tip to the adapters cord and set the barrel plugs tip to pos- itive. 2. Insert the adapters barrel plug into the DC 13.8V jack on the back of the scanner.3. Plug the adapter into a standard AC outlet. CONNECTING AN EXTENSION SPEAKER In a noisy area, an amplified extension speaker (available at your local Ra- dioShack store) positioned in the right place might provide more comfortable listening. Plug the speaker cable’s 1/8-inch (3.5- mm) plug into your scanner’s EXT SP jack. Note: Connecting an external speaker disconnects the scanner’s internal speaker. ! 12 V 20-196a.fm Page 11 Friday, June 2, 2000 3:48 PM
12 CONNECTING AN EARPHONE/ HEADPHONES For private listening, you can connect an earphone or headphones with a 1/8- inch (3.5-mm) plug to the EXT SP jack on the back of the scanner. (Your local RadioShack store carries a wide se- lection of earphones and head- phones). This automatically dis- connects the internal speaker. Listening Safely To protect your hearing, follow these guidelines when you use an earphone or headphones. • Do not listen at extremely high volume levels. Extended high- volume listening can lead to per- manent hearing loss. •Set VOLUME to the lowest setting before you begin listening. After you begin listening, adjust VOL- UME to a comfortable level.• Once you set 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. CONNECTING THE CLONE CABLE You can transfer the programmed data to and from another Cat. No. 20- 196 or Cat. No. 20-522 scanner using the supplied clone cable. Connect the cable between each scanner’s PC/IF jacks. See “Cloning Programmed Data from Scanner to Scanner” on Page 35. You can also upload or download the programmed data to or from a PC using an optional PC inter- face kit available through your local RadioShack store. 20-196a.fm Page 12 Friday, June 2, 2000 3:48 PM
13 Once you understand a few simple terms used in this manual and familiarize your- self with your scanner’s features, you can put the scanner to work for you. You sim- ply determine the type of communications you want to receive, then set the scanner to scan them. A frequency is the tuning location of a station (expressed in kHz or MHz). To find active frequencies, you can use the search function. You can also search the service-search banks , which are preset groups of fre- quencies 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 your 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. A LOOK AT THE KEYPAD Your scanner’s keys might seem confusing at first, but this information should help you understand each key’s function. Note: Some of the scanner’s keys perform more than one function and are marked with more than one label. The steps in this Owner’s Manual show only the label on the key appropriate to the action being performed. SCAN — scans through the programmed channels or ID code. WX — scans through the 7 preprogrammed weather channels. AT T (attenuate) — turns attenuation on to reduce the scanner’s sensitivity, or turns it off to increase it.

18 UNDERSTANDING BANKS Channel Storage Banks To make it easier to identify and select the channels you want to listen to, channels are divided into 10 banks (0–9) of 50 channels (00 to 49) each. Use each channel-storage bank to group frequencies, such as those used by the police department, fire de- partment, ambulance services, or air- craft (see “Guide to the Action Bands” on Page 45). For example, the police department might use four frequen- cies, one for each side of town. You could program the police frequencies starting with 000 (the 1st channel in bank 0) and program the fire depart- ment frequencies starting with 100 (the 1st channel in bank 1). The first digit identifies the bank (0–9). The second and third digits identify the channel within the bank (00–49). Search Banks This scanner is able to search 10 search banks. You can also replace a bank with one of the preprogrammed service bands. (For the default setting, see “Searching a Preprogrammed Frequency Range” on Page 25). UNDERSTANDING CTCSS/DCS Continuous Tone Coded Squelch Sys- tem (CTCSS) and Digital Coded Squelch (DCS) are two methods used to prevent interference by other radio communications. Your scanner can receive transmissions that use these codes. When your scanner receives a CTC- SS transmission, PL (private line) ap- pears. When your scanner receives a DCS transmission, DPL (digital private line) and a 3-digit code appear. PL Codes PL codes are low-frequency audio tones that are used to differentiate dif- ferent users on the same channel. PL codes appear according to the EIA standard CTCSS tones, and range from 67.0 Hz to 254.1 Hz. PL codes are displayed directly as a frequency. DPL Codes DPL codes are similar to PL codes, except they might be transmitted as either tones or digital codes. Although there are as many as 4096 DPL codes, only about 100 are actually used. DPL codes appear in the format Dxxx, where xxx is an octal code. 20-196a.fm Page 18 Friday, June 2, 2000 3:48 PM
19 UNDERSTANDING YOUR SCANNER’S MODES Open and Closed Modes You can set your scanner to change the way it receives signals. These set- tings, called open mode and closed mode , affect how the scanner re- ceives signals from communications systems that use some type of closed squelch (such as PL, DPL, LTR, MOT, and ED systems). You can set each of the scanner’s channel storage banks to open or closed mode. In open mode, the scanner scans sig- nals transmitted in all systems. In closed mode, the scanner scans sig- nals transmitted only under the follow- ing conditions: • When the signals are in the FM mode. • When the signals are in the LT, MO, or ED mode and the signals ID code matches the programmed ID code. • When the signals are in the PL or DPL mode and the signals ID code matches the programmed ID code. Note: When the signals are in the PL or DPL mode, the scanner receives all signals on a channel when the ID code is set to NONE. You can also select the users or talk groups you want the scanner to re- ceive in closed mode.When you set a channel storage bank to open mode, + (open) appears un- der the bank’s number while scanning. When you set a channel storage bank to closed mode, – (closed) appear un- der the channel storage banks num- ber while scanning. Or, OPEN or CLOSED appears while the scanner is in manual mode or while the scanner is receiving a signal during scanning. See “Changing the Open/Closed Mode” on Page 32 for more informa- tion about setting the open and closed modes. LTR (E. F. Johnson) Mode You can set your scanner so it de- codes the talk group IDs used with LTR systems. This setting is called the LTR mode. LTR systems are trunking systems used primarily by business or private communications service providers, such as taxicabs, delivery trucks, and repair services. These systems en- code all trunking information as digital subaudible data that accompanies each transmission. Users on an LTR system are assigned to specific talk groups, which are identified by the ra- dio as six-digit numbers. These num- bers are in the form AHHUUU, where: A = Area code (0 or 1) H = Home repeater (01 through 20) U = User ID (000 through 254) 20-196a.fm Page 19 Friday, June 2, 2000 3:48 PM
20 When the scanner receives a trans- mission on a channel set to the LTR mode, it first decodes the LTR data in- cluded with the transmission. In the open mode, the scanner stops on the transmission and displays the talk group ID on the bottom line of the dis- play. In the closed mode, the scanner only stops on the transmission if the LTR data matches a talk group ID that you have stored in the bank’s talk group ID list and have not locked out. LTR systems are frequently pro- grammed so that each radio has a unique ID code. Motorola Mode You can set your scanner so it de- codes the talk group IDs used with Motorola trunking systems. This set- ting is called the Motorola mode. Motorola systems are trunking sys- tems used primarily by business and public safety groups to efficiently allo- cate a small number of frequencies (as few as 5) to many groups of users (as many as several thousand). To do this, each group of users in the system is assigned to a specific talk group. For example, the east side patrol offic- ers might all be assigned to talk group 2160. One channel in the system is continuously transmitting data that identifies which talk groups are active on which channel. In addition, this talk group information is also transmitted as subaudible data on each active channel.When the scanner receives a trans- mission on a channel set to the Motor- ola mode, it first decodes the talk group ID data included with the trans- mission. In the open mode, the scan- ner stops on the transmission and displays the talk group ID on the bot- tom line of the display. In the closed mode, the scanner only stops on the transmission if the talk group ID matches a talk group ID that you have stored in the bank’s talk group ID list and have not locked out. Motorola trunking systems come in three categories: Type I, Type II, and Type I/II Hybrid. Each category dis- plays and uses talk group IDs in slight- ly different ways. Motorola Type I IDs are in the form FFF-SS, where: FFF = Fleet ID SS = Subfleet ID Type I systems are usually organized with different user groups assigned to different fleets. For example, a valid fleet/subfleet ID identifying all detec- tives within a police department might be 000-12, where 000 identifies all police users and 12 identifies the De- tective division. To properly map the raw Type I data to the correct fleet-subfleet format, you must program the correct fleet map into the scanner. Fleet map infor- mation is widely available on the Inter- net for most Type I systems in use. 20-196a.fm Page 20 Friday, June 2, 2000 3:48 PM
