    7.7.1 W3 Control Head
    1. Press > until REKY appears.
    2. Press 
    m below REKY.
    REQUEST REKY is displayed.
    3. Press the PTT button to send the rekey request.
    PLEASE WAIT is displayed.
    One of the following occurs:
    The radio sounds five tones when the dispatcher has 
    received the request.
    NOTE:Any subsequent pressing of the PTT button will exit the feature and allow 
    you to transmit in the normal manner. Pressing 
    O or the emergency button 
    also exits the feature.
    If the display momentarily shows 
    REKEY FAIL and a 
    bad-key tone sounds, the rekey operation failed 
    because the radio does not contain the Unique 
    Shadow Key (USK) or Unique Key Encryption Key 
    (UKEK).
    You have to load the USK into the radio using the 
    KVL before the radio can be reprogrammed over the 
    air.
    NOTE:If you exit at this point, but stay on the current channel in the dispatch mode, 
    the radio momentarily shows 
    REKEYED or DENIED and sounds a tone 
    indicating the status of the rekey request.
    If the display shows 
    NO ACK and a bad-key tone 
    sounds, then the dispatcher has not acknowledged 
    your request after the radio has tried five times to 
    send it.
    The radio then returns to the display message in step 
    2, allowing you to retry the request.
    If the request is accepted and the radio is 
    successfully rekeyed, the display momentarily shows 
    REKEYED.
    If the display momentarily shows 
    DENIED and a bad-
    key tone sounds, the request has been denied by the 
    dispatcher, and the radio returns to the home display.

    5. One of the following occurs:
    If the radio receives an acknowledgment from the dispatcher, five tones 
    sound.
    If the radio does not receive an acknowledgment from the dispatcher, the

    							Chapter 8 Disassembly/Reassembly Procedures
    8.1 Introduction
    This section details the procedures necessary to remove and replace the printed circuit board in the 
    ASTRO XTL 5000 radio. After troubleshooting and determining what needs to be replaced, 
    disconnect the test equipment, the antenna cable, and the power cable.
    Locate the exploded view of the radio in Chapter 11. Exploded Views and Parts Lists. Keep it handy 
    for reference as you disassemble and reassemble the radio.
    When installing a new circuit board, all mounting screws should be started before any are torqued. 
    This will help ensure proper alignment.
    After installing a new board, perform a complete alignment procedure as outlined in Chapter 6. 
    Radio Alignment Procedures.
    8.2 Replacement Procedures
    8.2.1 Required Tools and Supplies
    Disconnect the power cable from the radio before 
    opening and removing the PCB. Failure to remove power 
    can result in unit damage caused by transients or 
    accidental shorts, as well as presenting a shock hazard.
    After performing alignment procedures, always exit the SERVICE menu 
    entirely (to the MAIN MENU) to properly save all changes. Failure to do so can 
    result in an alignment, or other, failure.

    NOTE:Bracketed numbers are identical to item numbers shown in  Figure 11-1. “W3 Hand-Held 
    Control Head Exploded View” on page 11-2 .
    1. Remove the strain-relief boot covering the control-head cable connector [15] from the  housing assembly [7] by pulling it away from the control head until they are completely 
    separated.
    2. Carefully remove the rubber seal (part of cable assembly [15]) from the housing assembly [7]  opening.
    NOTE: Take care to avoid damaging this seal.
    3. Using a small screwdriver, remove the seal support wedge [14] from the control head.
    4. Using a small screwdriver to depress the telco lever, remove the telco connector at the end of  the cable assembly [15] from the control head, and pull the cable assembly away from the 
    housing (like a telephone jack).
    5. Remove the rear cover assembly [2] from the control head.
    Locate the recesses in the lower portion of the housing on both sides of the rear cover’s snap 
    features and, prying the snaps until the two parts separate, remove the rear cover from the 
    unit.
    6. Remove the two snap retainers [4] from between the SB9600 circuit board [5] and the  housing assembly [7].
    7. Disconnect the microphone assembly [8] connector from the SB9600 circuit board [5].
    8. Carefully remove the microphone assembly [8] from the keypad [6].
    NOTE:Be careful to avoid damaging circuit-board components in the next step.
    9. There are seven snaps locking the circuit board to the housing. Carefully pry the housing’s  snap features from the SB9600 circuit board [5]. As the snap features are deflected, push the 
    circuit board upward, using the keypad, to release the circuit board from the snap features.

    Head Exploded View” on page 11-2 .
    1. Insert the transmit indicator [11] into the housing assembly [7]. Ensure that the top surface of  the lightpipe is below the label recess of the housing.
    2. Attach the nameplate label [13] to the front of the housing assembly [7]. Ensure that the label  is securely attached.
    3. Install the PTT actuator [9] into the housing assembly [7]. Ensure that its lip is seated in the  grove in the housing.
    4. Install the PTT lever [10] and the PTT boot [12] into the housing assembly [7]. Ensure that the  lever is seated in its nest and the boot is located properly in the recesses in the housing.
    5. Install the keypad [6] into the housing assembly [7]. Ensure that all of the keys are located in  the correct openings in the housing.
    6. Install the microphone assembly [8] into the keypad. Ensure that the front surface of the  cartridge is located up against the keypad membrane.
    NOTE: The membrane is the rain seal and is very sensitive to puncture by sharp objects.
    7. Connect the microphone assembly [8] connector to the mating location on the SB9600 circuit  board [5].
    8. Install the circuit board [5] into the housing assembly [7] as follows:
    a. Hold the housing assembly so that its key openings face downward and its top faces away from you.
    b. Insert the circuit board’s display down under the housing retention features, and rotate the  board downward, ensuring that the board is positioned between the snap features. Ensure 
    that the microphone assembly’s [8] wire passes through the opening in the circuit board.
    c. Press downward firmly on the board until the seven snap features lock the board into  place.
    9. Install the two snap retainers [4] between the circuit board and the side wall of the housing  assembly [7], one on each side.
    10. Install the main seal [3] onto the rear cover assembly [2], placing the seal under the retainer  features around the perimeter of the cover.
    11. Install the rear cover assembly [2] onto the housing assembly [7]. Starting at the top of the cover, pivot the cover toward the housing and squeeze the two 
    halves together until the snap features at the lower end of the rear cover engage the 
    housing’s features and snap closed.
    12. Insert the cable assembly’s [15] telco connector into the opening in the bottom of the housing,  ensuring that it correctly is oriented.
    13. Press the telco connector in place until it snaps in (like a phone plug).
    14. Place the seal support wedge [14] into the housing’s opening, orientating it so that its long  portion is under the telco connector lever, and then push until it is properly seated.
