Page 10: Introduction
1 Introduction 1.1 Scope of Manual The purpose of this manual is to provide planning and installation personnel with the appropriate procedures for the Trailblazer Digital Microwave Radio and its accessory equipment. In order to avoid harm to persons or damage to the product, please ensure that you have read and understand the safety, unpacking and installation sections before proceeding. - Page 11 The low power consumption of 2 to 5 Watts makes the Trailblazer very energy efficient. The Trailblazer operates at any DC voltage from 12V to 24V and is thus easily powered by a solar system. CWT solar powering kits are available with up to 7 days of back-up power.
