It can store frequencies such as police, fire/emergency, marine, air, amateur, and other communications into 10 banks of 30 channels each. Use your new scanner to monitor: 800 MHz Trunked Public Safety Systems Police and Fire Departments (including rescue and paramedics) NOAA Weather Broadcasts Business/Industrial Radio Utilities Marine and amateur (ham radio) bands Air band Frequency Range 29. 0-29. 7 MHz 29. 7-50. 0 MHz 50. 0-54. 0 MHz 108-137 MHz 137-144 MHz 144-148 MHz 148-174 MHz 406-420 MHz 420-450 MHz 450-470 MHz 470-512 MHz 806-956 MHz Steps 5 kHz 5 kHz 5 kHz 12. 5 kHz 5 kHz 5 kHz 5 kHz 12. 5 kHz 12. 5 kHz 12. 5 kHz 12. 5 kHz 12. 5 kHz Transmission 10 Meter Amateur Band VHF Low Band 6 Meter Amateur Band Aircraft Band Military Land Mobile 2 Meter Amateur Band VHF High Band Federal Govt. 70cm Amateur Band UHF Standard Band UHF "T" Band Public Service "800" Band 3 Important Notice This scanning radio has been manufactured so that it will not tune to the radio frequencies assigned by the FCC for cellular telephone usage. [. . . ] Determining the exact Fleet-Subfleet hierarchy for a particular area is referred to as Fleet Map Programming. The disadvantage of a Type I system is that when PTT is pressed, the brief bust of data must contain the radio's ID and its Fleet and Subfleet. This is three times the amount of data a Type II system radio sends, and as a result Type I systems usually accommodate fewer users than Type II systems. Even though there are many Type II systems, Type I systems are still in use. There are also Hybrid systems which are a combination of both Type I and Type II. Your scanner defaults to monitor Type II systems, but it's possible to select a Preprogrammed Fleet Map or create a Custom Fleet Map for your area. 36 Setting the Squelch Since Squelch is automatically adjusted in trunking mode, it isn't necessary to manually adjust the squelch control while trunk tracking. However, the squelch setting you select before you begin trunk tracking can affect how fast your scanner acquires the data channel, and, in some instances, the squelch setting can prevent your scanner from acquiring the data channel at all. Set SQUELCH in this position before selecting a trunking bank. Note: You can change this recommended setting, if necessary, to provide better performance in your area. Programming Trunking Frequencies Before you start programming your scanner to track a trunked system, consider the following: You can only program one trunking system in each bank of your scanner. Trunking frequencies must be entered while in the Trunking Programming mode. If you're in the Trunking Programming mode, you cannot select channels in other banks. For example, if you are programming Bank 4, you can only select channels 91-120 with the( or) keys. 37 The first step in tracking a trunked system is storing the frequencies in one of the 10 available banks in your scanner. Press and hold T. You will hear two beeps, and BANK and TRUNK will begin to flash in the display. 2. Choose the bank you want to trunk track. For example, enter 856. 2625, or enter a frequency of the system you're going to track. Then press E. BANK TRUNK 1 2 3 4 5 6 7 8 9 10 3. Note: To clear a mistake while entering a frequency, press . If you enter a non-800 MHz trunked repeater output frequency, an error message displays. and go back to Step 3. 1 2 3 4 5 6 7 8 9 10 38 4. Press either M or) to select the next channel in the bank. 1 2 3 4 5 6 7 8 9 10 5. Repeat steps 3 and 4 until all frequencies have been entered. Press R to begin searching the bank you've programmed. BANK TRUNK 1 2 3 4 5 6 7 8 9 10 6. Note: You will see the frequencies quickly displaying as your scanner looks for the data channel which controls the system. Searching a Trunked Bank Before you Search a Trunked Bank with your scanner, consider the following: You can only trunk track one bank at a time. Use T to toggle between the conventional and the trunk tracking modes. Press D while in the Trunk Tracking mode to review which bank is currently in use. The appropriate bank icon will flash at the top of the display for 5 seconds. 39 If you have programmed frequencies for a trunked system in one or more of the 10 available banks and you are in conventional mode, follow these steps to begin trunk searching: 1. For example press 2. BANK TRUNK 1 2 3 4 5 6 7 8 9 10 Note: You will see the frequencies quickly displaying as your scanner looks for the data channel which controls the system. Talk group ID's, which represent different service groups, begin to display. 3. [. . . ] Otherwise you might experience some discomfort or possible hearing damage if the volume suddenly becomes too loud because of the Volume Control or Squelch Control setting. This may be particularly true of the type of earphone that is placed in the ear canal. WARNING! Uniden does not represent this unit to be waterproof.
