    1-2Introduction: Control Head Descriptions
    ASTRO Digital Spectra and Digital Spectra Plus radios are available in five models. Table 1-1 
    provides a description of basic features for the five models covered in this manual.
    1.2.1 FLASHport®
    The ASTRO Digital Spectra and Digital Spectra Plus radios utilize Motorola’s revolutionary 
    FLASHport technology. FLASHport makes it possible to add software that drives the radio’s 
    capabilities both at the time of purchase and later on. Previously, changing a radio’s features and 
    capabilities meant significant modifications, or buying a new radio. But now, the radio’s features and 
    capabilities can be upgraded with FLASHport software, similar to the way a computer can be loaded 
    with different software.
    1.3 Control Head Descriptions
    1.3.1 General
    The control heads used with ASTRO Digital Spectra and Digital Spectra Plus radios have 
    microprocessor circuitry that operates the standard and optional features built into the system. The 
    control head design allows installation in even the smallest of vehicles. Systems that have many 
    options require more control head buttons, not larger control heads.
    The control heads may be field-programmed to add options or alter the information stored in certain 
    areas of its electronic memory.
    The following illustrations show some typical ASTRO Digital Spectra and Digital Spectra Plus control

     Power Switch — The power (PWR) switch turns the radio and its accessories on or off. The 
    power switch is part of the rotary volume knob on the W4 model, a push-type switch on the W5 
    and W7 models, and a slide switch on the right-hand bottom surface of the W9 model.
     Mode Switch — The Mode switch is used for selecting modes and programming menus. The 
    Mode switch is a rotary switch on the W4 model and a rocker switch on the W5, W7, and W9 
    models. Pressing the right side of this rocker switch increases the mode number. Pressing the 
    left side decreases the mode number. If you press and hold the switch, it scrolls the mode 
    number up or down. The mode names appear in the display window.
     Volume Switch — The Volume switch is used for selecting the volume level, editing names, and 
    making certain radio adjustments. The Volume switch is a rotary switch on the W4 model and a 
    rocker switch on the W5, W7, and W9 models. On the pushbutton models, pressing and 
    releasing the volume switch checks the volume setting. Your display will show “VOLUME_ _” 
    and a number value (0-15). Press and hold the left side to decrease the volume. The number 
    value scrolls up or down to your desired level. The Volume rocker switch also controls the 
    volume level of the public address (PA) and external radio speaker (Ex Rd) options when they 
    are enabled. The display window shows “PA VOL _ _” when public address is on and the 
    Volume rocker switch is pressed.
     Dim Button — The DIM button is used to control the brightness of the display and button 
    backlighting. When you turn on the system, the display comes on at the brightness level it was 
    on before the system was last turned off. Press the DIM button once to reduce the brightness of 
    the display to medium level and twice for low brightness level. Press the DIM button a third time 
    to turn the display and button backlighting off. This is called the “surveillance” mode.
     Home Button — The Home button is used for restoring preprogrammed mode, establishing 
    programmed mode, selecting programming entries, etc. Press the Home button to go to the 
    radio’s preprogrammed “home” mode. On the W7 models, you may use the Home button 
    instead of Mode switch to change modes. Hold the Home button until a beep sounds to enter 
    the configuration state. The display shows an entry prompt. Use the keypad to enter your new 
    mode choice and press the Home button again. Your mode is now changed without scrolling.

    							Chapter 2 Basic Maintenance
    2.1 Introduction
    This section of the manual describes preventive maintenance, handling precautions, and some basic 
    repair procedures and techniques. Each of these topics provides information vital to the successful 
    operation and maintenance of your radio.
    2.2 Preventive Maintenance
    Radios are shipped from the factory with a worst-case frequency error of ±200 Hz for VHF, ±300 Hz 
    for UHF, and ±500 Hz for 800 MHz. These specifications are tighter than the most stringent FCC-
    required specifications of 2 ppm (parts per million) for both VHF and UHF, and 1.5 ppm for 800 kHz, 
    within which the radio will operate to specification.
    2.2.1 Reference Oscillator
    For radios that have been in storage for over six months from the factory ship date, the reference 
    oscillator should be checked when the radio is initially deployed to the field. It is strongly 
    recommended that the reference oscillator be checked every time the radio is serviced or at least 
    once a year, whichever comes first.
    The crystal contained in the reference oscillator naturally drifts over time due to its aging 
    characteristic. Periodic (annual) adjustment of the reference oscillator is important for proper radio 
    operation.
    Improper adjustment can result in both poor performance and interference with other users operating 
    on adjacent channels.
    A recommended test setup and tuning procedure is detailed in Chapter 6. Radio Alignment 
    Procedure. The frequency counter used for this procedure must have a stability of 0.1 ppm or better.
    2.2.2 Inspection
    Check that the external surfaces of the radio are clean, and that all external controls and switches 
    are functional. A detailed inspection of the interior electronic circuitry is not needed.
    2.2.3 Cleaning
    The following procedures describe the recommended cleaning agents and the methods to be used 
    when cleaning the external and internal surfaces of the radio. External surfaces include the control 
    head and radio chassis. These surfaces should be cleaned whenever a periodic visual inspection 
    reveals the presence of smudges, grease, and/or grime. Internal surfaces should be cleaned only 
    when the radio is disassembled for servicing or repair.
    The only recommended agent for cleaning the external radio surfaces is a 0.5% solution of a mild 
    dishwashing detergent in water. The only factory recommended liquid for cleaning the printed circuit 
    boards and their components is isopropyl alcohol (70% by volume). 
    						
    							February 3, 20036881076C20-E
    2-2Basic Maintenance: Handling Precautions
    2.2.4 Cleaning External Plastic Surfaces
    The detergent-water solution should be applied sparingly with a stiff, non-metallic, short-bristled 
    brush to work all loose dirt away from the radio. A soft, absorbent, lint-free cloth or tissue should be 
    used to remove the solution and dry the radio. Make sure that no water remains entrapped near the 
    connectors, cracks, or crevices.
    2.2.5 Cleaning Internal Circuit Boards and Components
    Isopropyl alcohol may be applied with a stiff, non-metallic, short-bristled brush to dislodge embedded 
    or caked materials located in hard-to-reach areas. The brush stroke should direct the dislodged 
    material out and away from the inside of the radio.
    Alcohol is a high-wetting liquid and can carry contamination into unwanted places if an excessive 
    quantity is used. Make sure that controls or tunable components are not soaked with the liquid. Do 
    not use high-pressure air to hasten the drying process, since this could cause the liquid to puddle 
    and collect in unwanted places.
    Upon completion of the cleaning process, use a soft, absorbent, lint-free cloth to dry the area. Do not 
    brush or apply any isopropyl alcohol to the frame, front cover, or back cover.
    NOTE:Always use a fresh supply of alcohol and a clean container to prevent contamination by 
    dissolved material (from previous usage).
    2.3 Handling Precautions
    Complementary metal-oxide semiconductor (CMOS) devices, and other high-technology devices, 
    are used in this family of radios. While the attributes of these devices are many, their characteristics 
    make them susceptible to damage by electrostatic discharge (ESD) or high-voltage charges. 
    Damage can be latent, resulting in failures occurring weeks or months later. Therefore, special 
    precautions must be taken to prevent device damage during disassembly, troubleshooting, and 
    repair. Handling precautions are mandatory for this radio, and are especially important in low-
    humidity conditions. DO NOT attempt to disassemble the radio without observing the following 
    handling precautions:
     Eliminate static generators (plastics, Styrofoam, etc.) in the work area.
     Remove nylon or double-knit polyester jackets, roll up long sleeves, and remove or tie back 
    loose-hanging neckties.
     Store and transport all static-sensitive devices in ESD-protective containers.
     Disconnect all power from the unit before ESD-sensitive components are removed or inserted 
    unless otherwise noted.
     Use a static-safeguarded workstation, through the use of an anti-static kit (Motorola part 
    number 01-80386A82). This kit includes a wrist strap, two ground cords, a static-control table 
    mat and a static-control floor mat.
    NOTE:Be sure that the table and floor mats are properly grounded.
    When these items are not readily available, observing the following techniques will minimize the 
    chance of damage:The effects of certain chemicals and their vapors can have 
    harmful results on certain plastics. Aerosol sprays, tuner 
    cleaners, and other chemicals should be avoided.

    Basic Maintenance: Handling Precautions2-3
     If a static-sensitive device is to be temporarily set down, use a conductive surface for 
    placement of the device.
     Make skin contact with a conductive work surface first and maintain this contact when the 
    device is set down or picked up.
     Always wear a conductive wrist strap when servicing this equipment. The Motorola part number 
    for a replacement wrist strap that connects to the table mat is 42-80385A59.
     For additional information, refer to Service and Repair Note SRN-F1052, Static Control 
    Equipment for Servicing ESD Sensitive Products, available from the Literature Distribution 
    Center.
