20-522.fm Page 12 Friday, September 17, 1999 12:46 PM 3. Insert six AA batteries in the battery holder as indi- cated by the polarity symbols (+ and –) marked on the holder. Cautions: • Use only fresh batteries of the required size and recommended type.
Warning: Always dispose of old batteries promptly and properly. Do not bury or burn them. Caution: If you do not plan to use the scanner with bat- teries for a month or longer, remove the batteries. Batter- ies can leak chemicals that can destroy electronic parts.
RadioShack store, recycling collection centers, and mail-back programs. Using AC Power You can power the scanner using an 9V, 300 mA AC adapter and a size H Adaptaplug (neither supplied). We recommend RadioShack Cat. No. 273-1767 (available at your local RadioShack store).
3. Plug the adapter into a standard AC outlet. Using Vehicle Power You can power the scanner from a vehicle’s 12V power source (such as a cigarette-lighter socket) using a 9V, 300 mA DC adapter and a size H Adaptaplug (neither supplied).
20-522.fm Page 16 Friday, September 17, 1999 12:46 PM 3. Plug the adapter’s cigarette-lighter plug into your vehicle’s cigarette-lighter socket. Note: If the scanner does not operate properly when you connect a DC adapter, unplug the DC adapter from the cigarette-lighter socket and clean the socket to remove ashes and other debris.
Connecting an Optional 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. Your local RadioShack store sells a variety of antennas.
CONNECTING AN EXTENSION SPEAKER In a noisy area, an amplified speaker (not supplied), available at your local RadioShack store, might provide more comfortable listening. Plug the speaker cable’s inch (3.5-mm) mini-plug into your scanner’s jack.
Slide the belt clip over your belt or waistband. CONNECTING THE CLONE CABLE You can transfer the programmed data to and from an- other PRO-92 using the supplied clone cable. Connect the cable between each scanner’s PC/IF jacks. See “Cloning the Programmed Data from Scanner to Scan- ner”...
Once you understand a few simple terms used in this manual and familiarize yourself with your scanner’s fea- tures, 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.

TALK GROUP ID’S You can program up to 100 talk group ID’s in each bank. When the scanner stops on a transmission in the LTR, Motorola, or EDACS mode, it checks to see if the ID has been stored. In the Closed mode, the scanner only stops on the transmission and displays its text tag if you have stored and not locked out the ID.
Steps 4 and 5 to enter more IDs. 8. Press to start scanning. SCAN Talk Group ID Hold You can set your scanner to follow a trunking signal, which you wish to track while scanning. Hold down more than 2 seconds. TRUNK the display.
Locking Out Talk Groups ID Note: You can only lock out talk group ID’s when the scanner is in the closed mode (see “Open and Closed Modes” on Page 63). To lock out a talk group ID, follow these steps: 1.
OPEN AND CLOSED MODES When set to the open mode, the scanner only uses the ID list to look up ID text tags and stops on any ID code. When set to the closed mode, the scanner stops only on signals that have an ID code that is found in the ID list for the bank.
OPEN/CLOSED mode at the top line while the scanner is in manual mode or while the scanner is receiv- ing a signal during scanning. When no ID code is programmed into the scanner, it re- ceives the signal in PL, DPL, LTR, MOT, or ED mode without regarding the open or closed mode.
