21 SPECIAL FEATURES DELAY Many agencies use a two-way radio system that might have a period of 2 or more seconds between a query and a reply. To keep from missing a reply, you can program a 2-second delay into any channel or frequency. The scanner continues to monitor the fre- quency for 2 seconds after the trans- mission stops before resuming scanning or searching. To program a 2-second delay: • If the scanner is scanning chan- nel-storage banks and stops on an active channel where you want to store a...

22 LOCKING OUT CHANNELS AND FREQUENCIES You can scan existing channels or search frequencies faster by locking out channels or frequencies that have a continuous transmission, such as a weather channel. Note: If you just want to skip over a lengthy transmission (such as a mo- dem signal), see “Skipping Data Sig- nals” on Page 23. Locking Out Channels To lock out a channel while scanning, press L/O when the scanner stops on the channel. To lock out a channel manually, select the channel and press L/O...

23 TURNING THE KEY TONE ON AND OFF To turn the key tone off, turn off the scanner. Then, while holding down L/O/SKIP, turn on the scanner. OF bEEP appears. To turn the key tone back on, repeat the above procedure. oN bEEP ap- pears. CHANGING SEARCH SPEEDS The PRO-2050 has two search speeds for a limit search. To switch between the normal and Hy- perSearch speeds, during a limit search, press SPEED. SEARCH flash- es during HyperSearch. Note: You can use HyperSearch only in the 5 kHz step bands...

24 PRIORITY The priority feature lets you scan through channels and still not miss im- portant or interesting calls on specific channels. You can program one stored channel in each bank as a pri- ority channel (for up to a total of 10 stored channels). As the scanner scans the bank, if the priority feature is turned on, the scanner checks the pri- ority channel for activity every 2 sec- onds. The scanner automatically desig- nates each banks first channel as its priority channel. Follow these steps to...

25 TYPES OF TRUNKING SYSTEMS Your trunk tracking scanner can moni- tor two basic types of systems — Type I and Type II. Instead of selecting a specific frequency to transmit on, a trunked system chooses one of sever- al frequencies in a 2-way radio user’s talk group when that user presses PTT (push to talk). Thus, trunking sys- tems allocate a few frequencies among many different users, but the way Type I and Type II systems do this is slightly different. One important distinction between these...

26 SETTING THE SCANNER TO THE TRUNK TRACKING MODE Press TRUNK to switch between the scanner’s conventional and trunk tracking modes. SETTING SQUELCH FOR THE TRUNK TRACKING MODE Your scanner’s squelch setting is au- tomatically adjusted in the trunking mode, which means you do not need to manually adjust squelch while tracking trunked transmissions. How- ever, the squelch setting can affect how fast your scanner acquires the data channel, and, in some instances, can prevent your scanner from acquir-...

27 2. Select the bank you want to store the trunked system’s frequencies in by pressing a number key. The scanner automatically selects the first channel in the bank. 3. Use the number keys to enter the trunked system’s frequencies, then press E. 4. Note: If you entered an invalid fre- quency in Step 3, the scanner beeps, the channel number flashes and Error appears. If this happens, press CLEAR to clear the frequency, then repeat Step 3. 5. Press either MANUAL or s to select the next channel in the...

28 Note: To see the bank currently in use for about 5 seconds, press DATA while in the trunk tracking mode. 3. To return to conventional scan- ning, press TRUNK again. Hint: While scanning, you will not know exactly whom the IDs are as- signed to until you listen awhile or until you locate ID lists in frequency guides or on internet sites such as www.trunkscanner.com. Within a few minutes, you can usually figure out if what you are listening to is a police, fire, or emergency medical 2-way ra- dio user....

29 To lock out an ID, press L/O when the ID appears. The ID is locked out, and the next ac- tive ID appears. Unlocking a Single ID 1. Hold down L/O until you hear two short beeps. 2. Repeatedly press t or s to select the ID you want to unlock. 3. Press L/O. The ID is unlocked and the next locked ID appears. 4. Press SEARCH to continue the scanner’s previous function. Unlocking All IDs Hold down L/O until you hear two short beeps. Then press E to unlock all the IDs at once. The scanner beeps twice....

30 Monitoring IDs You can use your scanner’s display to monitor the frequencies in a trunked system for activity. You cannot hear conversations in this mode, but this is an excellent way to determine which talk groups are the most active. To set the scanner to monitor IDs, hold down SEARCH until the scanner beeps twice. SEARCH flashes, and all active talk group IDs appear in succession. To stop monitoring IDs, press SEARCH again. Note: When you monitor IDs, locked- out IDs also appear. CHANNEL ACTIVITY...
