General Safety. NEVER hold the antenna when theRF Module is “IN USE”. Keep all parts of the body at least 8inches ( 20cm) from Antenna whip. ELECTROMAGNETIC INTERFERENCE Most electronic devices are susceptible to electromagnetic interference (EMI). To avoid electromagnetic interference and/or compatibility conflicts, turn off the X-Ponder anywhere posted notices instruct you to do so. The Health Industry Manufacturers Association recommends that a minimum separation of 6 inches (15 centimeters) be maintained between a wireless radio and a pacemaker. Turn the unit OFF immediately if you feel that interference is taking place. Digital radios may interfere with some types of hearing aids. If such interference occurs, you may want to consult ithe aids manufacturer. EXPLOSIVE ATMOSPHERES Do not operate the X-Ponder in any area with a potentially explosive atmosphere. Areas such as fueling areas, chemical handling facilities, or areas where the air contains chemicals or particles, such as grain dust or metal powders. NEVER charge,remove or install batteries as sparks in such a potentially explosive atmosphere can cause an explosion or fire resulting in injury or death. To avoid possible interference with blasting operations, do not operate the module near electrical blasting caps, in a blasting area, or in areas posted: “Turn off two-way radio.” Always obey all signs and instructions.

Digital XTS 3000 Portable Radios Basic Service Manual Motorola8000 West Sunrise BoulevardFort Lauderdale, Florida 33322 68P81083C85-O TM TM *6881083C85* Foreword This manual covers all models of ASTRO™ Digital XTS 3000™ portable radios, unless otherwise specified. It includes all the information necessary to maintain peak product performance and maximum working-time using the pass/fail service approach. This basic level of service is typical of some local service centers, self-maintained customers, and some distributors. Included in this manual are: radio specifications for the 800MHz frequency band; a general description of ASTRO Digital XTS 3000 models; recommended test equipment, service aids, and tools; radio alignment procedures; fundamental disassembly/ reassembly procedures; and general maintenance recommendations. For details on the operation of the radio, or board- or component-level troubleshooting, refer to the applicable manuals available separately. To help you with your selection, a list is provided in this manual, titled “Related Publications.” Safety Information In 1991 the Institute of Electrical and Electronics Engineers (IEEE), and in 1992 the American National Standards Institute (ANSI), updated the 1982 ANSI Standard for safety levels with respect to human exposure to RF energy. Over 120 scientists, engineers, and physicians from universities, government health agencies, and industry, after reviewing the available body of research, developed this updated Standard. In March, 1993, the Federal Communications Commission (FCC) proposed the adoption of this updated Standard. Motorola subscribes to the same safety standard for the use of its products. Proper operation of this radio will result in user exposure substantially below FCC recommended limits: • DO NOT hold the radio with the antenna very close to, or touching, exposed parts of the body, especially the face, ears, or eyes, while transmitting. Hold the radio in a vertical position with the microphone two to three inches away from the lips. • DO NOT hold the transmit switch (PTT) on when not actually desiring to transmit. • DO NOT allow children to play with any radio equipment containing a transmitter. • DO NOT operate this equipment near electrical blasting caps or in an explosive atmosphere. Under certain conditions, radios can interfere with blasting operations. When you are in the vicinity of construction work, look for, and observe, signs cautioning against radio transmissions. If radio transmission is prohibited, you must not transmit until out of the area. Furthermore, you must turn off your radio to prevent any accidental transmission. • DO NOT replace or charge batteries in a hazardous atmosphere. Contact sparking may occur while installing or removing batteries and cause an explosion. • Turn the radio off when removing or installing a battery. Anyone intending to use a radio in a hazardous area is advised to become familiar with the subject of intrinsic safety and with Section 70 of the National Fire Code, which is commonly referred to as Article 500 of the National Electric Code. Use of anything but factory supplied components may affect the approval and safety of the radio. Likewise, it is advised that servicing should be performed only by qualified personnel who adhere to the following Factory Mutual (FM) required warning: Modification of FM approved intrinsically safe radios will negate Factory Mutual Research Corporation (FMRC) approval. Airbag Warning Statement VEHICLES EQUIPPED WITH AIR BAGS An air bag inflates with great force. DO NOT place objects, including communication equipment, in the area over the air bag or in the air bag deployment area. If the communication equipment is improperly installed and the air bag inflates, this could cause serious injury. • Installation of vehicle communication equipment should be performed by a professional installer/technician qualified in the requirements for such installations. An air bag’s size, shape and deployment area can vary by vehicle make, model and front compartment configuration (for example, bench seat vs. bucket seats). • Contact the vehicle manufacturer’s corporate headquarters, if necessary, for specific air bag information for the vehicle make, model and front compartment configuration involved in your communication equipment installation.

6-1 Vocoder and Controller Boards Detailed Theory of Operation 6 Introduction to This Section This section of the manual provides a detailed circuit description of the ASTRO Digital XTS 3000 vocoder and controller boards. When reading the theory of operation, refer to your appropriate schematic and component location diagrams located in the back section of this manual. This detailed theory of operation will help isolate the problem to a particular component. General The controller board is the central interface among the various subsystems of the radio. It is very similar to the digital logic portion of the controllers on many existing Motorola radios. Its main task is to interpret user input, provide user feedback, and schedule events in the radio operation, and includes programming ICs, steering the activities of the DSP, and driving the display. The vocoder board performs the functions which were previously performed by analog circuitry. This includes all tone signaling, trunking signalling, conventional analog voice, etc. All analog signal processing is done digitally utilizing a DSP56001. In addition, the vocoder board provides a digital voice-plus-data capability, utilizing VSELP or IMBE voice compression algorithms. Vocoder is a general term used to refer to these DSP based systems and is short for voice encoder. The vocoder and controller boards are connected through a 50-pin compression connector; they provide interconnection among the microcontrol unit (MCU), the DSP, and (on secure-equipped radios) the encryption board. Vocoder Board Refer to Figure 6 and the appropriate schematic diagram. The vocoder board consists of a digital signal processor (DSP — U405), 32k x24 static-RAM (SRAMs — U401, U402, and U403), a 256kB FLASH ROM (U404), and an ABACUS/DSP support IC (ADSIC — U406). The FLASH ROM (U404) contains the program code executed by the DSP. As with the FLASH ROM used on the controller board, the FLASH ROM is reprogrammable, so new features and algorithms can be updated in the field as they become available. Depending on the mode and operation of the DSP, corresponding program code is moved from the FLASH ROM into the faster SRAM, where it is executed at full bus rate. 6-2 The ADSIC (U406) is basically a support IC for the DSP. It provides, among other things, the interface from the digital world of the DSP to the analog world. The ADSIC also provides interrupt control for the DSP processing algorithms and some memory management. The configuration programming of the ADSIC is performed by the MCU. However, some components of the ADSIC are controlled through a parallel memory mapped register bank by the DSP. In the receive mode, The ADSIC (U406) acts as an interface with the ABACUS IC, which can provide IF data samples directly to the DSP for processing. Or, the IF data can be filtered and discriminated by the ADSIC and data provided to the DSP as raw discriminator sample data. The latter mode, with the ADSIC performing the IF filtering and discrimination, is the typical mode of operation.

The result is then sent to the audio PA for the speaker output. In the transmit mode, the ADSIC (U406) provides a serial digital-to- analog (D/A) converter. The data generated by the DSP is filtered and reconstructed as an analog signal, and sent to the VCO as a modulation signal. Both the transmit and receive data paths between the DSP and ADSIC are through the DSP SSI port. The amplified microphone signal is provided to the ADSIC, which incorporates an analog-to-digital (A/D) converter to translate the analog waveform to a series of data. The data is available to the DSP through the ADSIC parallel registers. In the converse way, the DSP writes speaker data samples to a D/A in the ADSIC, which provides an analog speaker audio signal to the audio PA. Controller Board Refer to Figure 7 and the appropriate schematic diagram The controller board consists almost entirely of digital logic comprising a microcontrol unit (MCU — U701), a custom support logic IC (SLIC — U702), and memory consisting of: SRAM (U705), EEPROM (U706), and FLASH memory (U727). The board also contains the audio PA (U718) and its associated circuitry. The MCU’s (U701) memory system is composed of a 32k x 8 SRAM (U705), a 32k x 8 EEPROM (U706), and 1M x 8 FLASH ROM (U727). The MCU also contains 1024 bytes of internal SRAM and 512 bytes of internal EEPROM.

The FLASH ROM contains the programs which the HC11F1 executes. The FLASH ROM allows the controller firmware to be reprogrammed for future software upgrades or feature enhancements. The SRAM is used for scratchpad memory during program execution. The SLIC (U702) performs many functions as a companion IC for the MCU. Among these are expanded input/output (I/O), memory decoding and management, and interrupt…
