PREFACE

The iDEN i850/i760 Digital Multi-Service, Data-Capable Portable Field Service Manual contains
the information necessary to identify and fix problems in the Motorola i850/i760 Digital Portable.
This unit is based on digital technology and is designed to operate on iDEN systems.
Basic and field-level service for the this unit as described in this manual includes troubleshooting,
testing, board swapping, and maintenance.
Service for this unit is based on the substitution method: a faulty part is replaced by a working one,
providing quicker service to the customer. For example, if the battery is faulty, it is replaced. If the
unit requires more complete testing or service than is available at the basic level, it is sent to the
field-level service facility, serviced, and returned to the iDEN Customer Care Center (ICC).
