    Search and Close Call Options
    On  The scanner automatically applies repeater reverse to 
    detected transmissions. If the scanner detects the 
    transmission on the output frequency, it beeps, REPEATER 
    FIND appears, and it remains on the output frequency until 
    transmissions end. If it does not detect a transmission on 
    the output frequency, it remains on the original frequency.
    Off   The scanner does not try to find the output frequency.

    Max Auto Store J E 
    This value sets how many hits the scanner will 
    automatically store when it is in either Search and Store 
    or Close Call Auto Store mode.
    Use the number keys to enter a value from 1 - 256, then

    Setting Attenuation
     J 4  Srch/CloCall Opt J E 4 
    Set Attenuation J E 
    This setting controls the attenuator for quick search and 
    Close Call operation. Select your setting, then press E.
    Off  The attenuator is off.
    On     Reception is attenuated by about 18 dB.
    Note: Turn on this setting if you are near other strong 
    signal sources. Attenuation sometimes helps to reduce 
    interference and desensitization that strong signals create.
    Setting Data Skip
     J 4  Srch/CloCall Opt J E 4 
    Set Data Skip J E 
    This setting controls how the scanner behaves when it 
    detects a constant-level transmission during quick search 
    or Close Call operation. Select your setting, then press E.
    Off  The scanner remains on the transmission until it ends.
    On   The scanner quickly resumes searching or Close Call 
    operation.
    Notes:
    • If you are trying to test the Close Call feature with a 
    nearby transmitter and you do not talk into the 
    transmitter, the scanner will detect this as data and 
    will skip the frequency when Data Skip is on. Turn the 
    feature off or talk into the transmitter.
    • The default for this feature is On.

    Using Weather Alert (SAME)
    Using Weather Alert  (SAME)Your scanner has been primarily designed to be a radio 
    scanner. While it incorporates weather alert as one of its 
    features, we strongly recommend that you not use the 
    scanner as your sole means for receiving emergency 
    alerts. Your local electronics retailer carries several 
    weather radios specifically designed for this function.
    Your scanner allows you to search for a local NOAA 
    weather broadcast and set it to alert when a SAME 
    weather alert is broadcast on a NOAA channel. You can 
    also program SAME codes into the scanner and set a 
    weather channel as a priority channel.
    In the following sections, you can also access the weather 
    menu from Hold mode by holding   then pressing Wx.
    Searching For a Weather Broadcast
     J 4  WX OPERATION J E J 
    Weather Scan 
    JE
    The scanner starts scanning the preprogrammed weather 
    frequencies, and stops on the first signal. If this station is 
    weak, rotate the scroll control to check for other weather 
    broadcasts in your area.
    Note: NOAA broadcasts are continuous broadcasts. 
    You will only lose reception if you move out of a coverage 
    area. If the signal is lost, the scanner resumes searching 
    for a weather transmission. 
    Turning Weather Alert On/Off
    In weather alert mode, your scanner functions as a 
    severe weather warning radio. This is especially useful 
    when your area is expecting severe weather conditions 
    late at night. When you set the scanner to weather alert 
    mode, it holds on the weather channel, but does not play 
    the channel’s audio. If it detects a weather alert, it sounds 
    a tone, displays information about the weather alert, and 
    turns on the audio so you can hear the weather broadcast.

    Weather Alert J 4
    This setting determines which types of signals will trigger 
    an alert. Select your setting, then press E.
    Alert Only - the scanner alerts when it detects the 
    1050 Hz tone that accompanies all weather alerts.
    ALL FIPS - the scanner alerts and displays information 
    about the weather alert when it receives any FIPS code 
    (see “Programming a SAME Group” on Page 95).
    SAME 1-5 - the scanner alerts and displays information 
    about the weather alert when it receives a weather alert 
    signal that includes any FIPS code you have 
    programmed into the specified SAME group.
    Programming a SAME Group
    You can edit any of the 5 SAME groups in your scanner. 
    Each group can have up to 8 FIPS codes.
    SAME (Specific Area Messaging System) is a system 
    developed by the National Weather Service to reduce the 
    number of alerts received by consumers by allowing them 
    to hear alerts only for the county(ies) they are interested 
    in. Each alert contains information about the type and 
    severity of the alert, as well as the specific geographic 
    locations affected by the alert.
    The geographic locations are designated using FIPS 
    codes. Each county or parish in the US and its territories 
    are assigned a FIPS code. In addition, certain special 
    regions and wildcard settings can be assigned.
    FIPS codes are in the format nSSCCC:
    n: A special subcounty designator. For an entire county, 
    use 0.
    SS: The state code.
    CCC: The county code.

    Using Weather Alert (SAME)
    For example, Tarrant County in Texas is assigned to FIPS 
    code 048439.
    0 indicates the entire county
    48 indicates the state of Texas
    439 indicates Tarrant County
    To get the FIPS code for your county, visit the National 
    Weather Service web site at http://www.nws.noaa.gov 
    and search for “FIPS Listing”.

    Care and Maintenance
    Care and MaintenanceGeneral Use
    • Turn the scanner off before disconnecting the power. 
    • Always write down the programmed frequencies in 
    the event of memory loss. 
    • If memory is lost, simply reprogram each channel.
    • Always press each button firmly until you hear the 
    entry tone for that key entry. 
    Location
    • Do not use the scanner in high-moisture 
    environments such as the kitchen or bathroom. 
    • Avoid placing the unit in direct sunlight or near 
    heating elements or vents. 
    • If the scanner receives strong interference or 
    electrical noise, move it or its antenna away from the 
    source of the noise. If possible, a higher elevation 
    might provide better reception. 
    • Also try changing the height or angle of the antenna. 
    Cleaning
    • Disconnect the power to the unit before cleaning. 
    • Clean the outside of the scanner with a mild 
    detergent. 
    • To prevent scratches, do not use abrasive cleaners or 
    solvents. Be careful not to rub the LCD window. 
    • Do not use excessive amounts of water.

    Care and Maintenance
    Repairs
    Do not attempt any repair. The scanner contains no user 
    serviceable parts. Contact the Uniden Customer Service 
    Center or take it to a qualified repair technician. 
    Birdies
    All radios can receive “birdies” (undesired signals). If your 
    scanner stops during Scan mode and no sound is heard, 
    it might be receiving a birdie. Birdies are internally 
    generated signals inherent in the electronics of the 
    scanner. 
    Press L/O to lock out the channel.
