February 3, 20036881076C20-E 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 heads.Table 1-1.

Typical W9 Pushbutton Control Head 1.3.1.4 Models W4, W5, W7, and W9 Controls 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.

Display — The vacuum fluorescent (VF) display’s primary function is to display mode numbers, mode names, volume level, and the status of options. It also functions as an on-off indicator for the entire system and plays an integral role in the operator’s reconfiguration of options. The display is 8 characters on W4, W5, and W7 models; 11 characters on the W9 model. XMIT and BUSY Indicators — The XMIT indicator lights when the radio is transmitting. The BUSY indicator lights when the selected channel is busy. Scan Indicators — When scan operation detects activity on a non-priority (NON-PRI) channel, the NON-PRI indicator light comes on. Activity on a second priority channel causes the priority (PRI) indicator to light. First priority channel activity causes PRI to flash. 12-Button Keypad (W7 and W9) — The keypad is used to change the status of options and for entering numbers. Several keys serve multiple functions. See the ASTRO Digital Spectra or Digital Spectra Plus User’s Guide for a complete description of keypad operation. -Site (Ste - #1 key) — Forces the radio to scan for a new site when the automatic multiple- site select (AMSS) feature for wide-area coverage is in use. - Page (2 or 2Pge - #2 Key) — Initiates a Call Alert page/enters Call ID list programming. -Lock (Lck - #3 key) — Locks the radio onto the current site when the AMSS feature is in use. -Status (Sts - #4 key) — Used alone or in conjunction with other keypad buttons and the Sel button to send a status transmission, indicating a predetermined condition change. - Regroup (Rpg - #5 key) — Requests a change in the radio’s talkgroup assignment when the dynamic regrouping feature is used. - Message (Msg - #6 key) — Used alone or in conjunction with other keypad buttons and the Sel button to transmit a message, indicating a response or temporary condition. - Horn/Lights (H/L - #7 key) — Selects/enables radio external alarms. - Monitor (Mon - #8 key) — Monitors the radio for channel traffic. - Direct/Simplex (Dir - #9 key) — Used for talkaround (mobile-to-mobile) conversations. - Recall (Rcl - * key) — Reviews modes in scan and phone lists. - Delete (Del - # key) — Used when editing stored lists.
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. ! C a u t i o n
6881076C20-EFebruary 3, 2003 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.
