Section I - GENERAL INFORMATION 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 pi- lot’s attention to the proper indicator. This system does not replace any existing annuncia- tion, but adds an additional layer of vigilance. -

Page 6: Section Ii - Installation
Equipment Installation Procedures 2.3.1 Cooling Requirements Forced air cooling of the PRD60 is not required. However the unit should be kept away from heat producing sources (i.e. defrost or heater ducts, dropping resistors, heat produc- ing avionics) without adequate cooling air provided. -
Page 7: Mounting Requirements
Avoid installing the PRD60 close to high current devices or systems with high-voltage pulse type outputs, such as DME or transponders. To install the PRD60, select a location convenient to the warning panel providing the output, and the audio panel. The unit may be installed in any position, on a surface that will allow for installation in accordance with AC43-13-2A. -

The output is on Pin 14. 2.4.5 Headset wiring The output of the PRD60 is usually presented to the pilot’s headset only, and only the left ear in a stereo installation. It is critical to the proper operation of this system to have this connector wiring made in accordance with these diagrams. -
Page 9: Adjustments
Connect the shields at one end only, and tie to the audio low inputs as shown. 2.5 Adjustments The PRD60 is factory adjusted to accommodate the typical requirements for most aircraft configurations. The output volume can be adjusted using Audio Adjustment pot. See Ap- pendix B for locations... -
Page 10: Section Iii Operation
3.2 Audio Messaging system The PRD60 contains six stored messages. An outside annunciator, such as an engine gage system triggers these messages. When there is an announcement, it will be repeated every two seconds until the remote- mounted ACK button is pushed. This stops the played an- nunciation, until the next announcement is required (the next falling edge). -
