Section I - GENERAL INFORMATION

1.1 INTRODUCTION

The PRD60 is an accessory device designed to improve the safety of flight by providing an aural annunciation of out of limit conditions. In a critical situation this directs the pilot’s attention to the proper indicator. This system does not replace any existing annunciation, but adds an additional layer of vigilance.

In addition, the unit contains a 4-channel summing amplifier to allow multiple unswitched audio sources to be combined into one output.

Before installing and/or using this product, please read this manual completely. This will ensure that you will take full advantage of all the advanced features in the PRD60.
