Introduction 1-1 Introduction 1 Scope of this Manual This manual includes model/kit information, speciÞcations, fundamental disassembly/reassembly procedures, maintenance, alignment, troubleshooting; and all theory, schematic diagrams, printed circuit board details and parts lists for all Non-Frequency Range SpeciÞc parts in the equipment listed. This manual is NOT a stand-alone manual, but requires the companionship of an appropriate Volume 2 manual in order to have all service information for a particular model of the radio. For every frequency band a band speciÞc Volume 2 manual will be available. By ordering the Complete Service Instructions, Motorola Publication Number 68P81080C40, you will receive Volume 1 as well as all Volume 2 band speciÞc manuals available at the time of ordering. In addition, for radios that are equipped with the Motorola SECURENET option, the SECURENET Service manual, Motorola Publication Number 68P81083C25, is required.
