ASTRO ® Digital Spectra® and Digital Spectra Plus UHF VHF 800 MHz Mobile Radios Basic Service Manual
i Tit le Pag e® Digital Spectra® and Digital Spectra Plus VHF/UHF/800 MHz Digital Mobile Radios Basic Service Manual Motorola, Inc. 8000 West Sunrise Boulevard Fort Lauderdale, Florida 33322 6881076C20-E
ii Foreword This manual covers all models of the ASTRO® Digital Spectra® and ASTRO Digital Spectra Plus mobile radios (models W3, W4, W5, W7, and W9), unless otherwise specified. It includes all the information necessary to maintain peak product performance and maximum working time, using levels 1 and 2 maintenance procedures. This level of service goes down to the board replacement level and is typical of some local service centers, self-maintained customers, and distributors. For details on radio operation or component-level troubleshooting, refer to the applicable manuals available separately. A list of related publications is provided in the section, “Related Publications,” on page xii. Product Safety and RF Exposure Compliance ATTENTION! This radio is restricted to occupational use only to satisfy FCC RF energy exposure requirements. Before using this product, read the RF energy awareness information and operating instructions in the Product Safety and RF Exposure booklet enclosed with your radio (Motorola Publication part number 6881095C99) to ensure compliance with RF energy exposure limits. For a list of Motorola-approved antennas, batteries, and other accessories, visit the following web site which lists approved accessories: http://www.motorola.com/cgiss/index.shtml Manual Revisions Changes which occur after this manual is printed are described in FMRs (Florida Manual Revisions). These FMRs provide complete replacement pages for all added, changed, and deleted items. To obtain FMRs, contact the Customer Care and Services Division (refer to “Appendix A Replacement Parts Ordering”).
