[. . . ] The Electronic Communications Privacy Act of 1986, as amended, makes it a federal crime to intentionally intercept cellular or cordless telephone transmissions or to market this radio when altered to receive them. The installation, possession, or use of this scanning radio in a motor vehicle may be prohibited, regulated, or require a permit in certain states, cities, and/or local jurisdictions. Your local law enforcement officials should be able to provide you with information regarding the laws in your community. Changes or modifications to this product not expressly approved by Uniden, or operation of this product in any way other than as detailed by this Operating Guide, could void your authority to operate this product. [. . . ] Their fleets might be the Police Department, the Fire Department, Utilities, and Administration. The Police may decide to further divide their fleet into subfleets such as Dispatch, Tactical Operations, Detectives, North, South, East and West Side Patrols, and Supervisors. All the available police radios would then be assigned to one of the police subfleets. 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. Press R to return to Search mode. Note: The ID Hold mode works in Scan List mode, and the steps are the same; however, SRCH doesn't appear in the display. 41 ID Lockout Like conventional scanning, it's possible to lockout unwanted traffic. This is particularly important in trunked systems because in many areas water meters, door alarms, traffic signals, and other mechanical devices are assigned IDs just like other users. Also some departments scramble or encrypt their communications, and you may want to lock out these unintelligible broadcasts. To lockout an ID, press O when the ID displays. The ID is locked out, and the next active ID displays. Note: If you lockout an ID in Search mode, it is also locked out in Scan List mode. Conversely, if you lockout an ID while in Scan List mode, it is locked out in Search mode. For information about Scan Lists see page 46. Restore a Single ID To unlock a single ID, follow these steps: 1. Press and hold O until you hear two short beeps. Use( or) to select the ID you want to unlock. 2. 3. Press O. The ID is unlocked and the next locked ID displays. 4. Press R to return to the Search mode. 42 Restore all IDs To unlock all locked out IDs at once, follow these steps: 1. Press and hold O until you hear two short beeps. [. . . ] Set the volume to a comfortable audio level coming from the speaker before plugging in the monaural earphone or a stereo headset of the proper impedance (32). 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. To reduce the risk of fire or electrical shock, do not expose this unit to rain or moisture. GENERAL BATTERY WARNING! Do not short-circuit any Battery. [. . . ]
