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.
