1. INTRODUCTION

Enjoy your AU-800 and make sure to read this Manual carefully before operation!

Thank you for your purchasing the AU-800 LTO wireless system.

Your AU-800 is based on a new revolutionary UHF PLL (phase loop locked) circuit
which allows the simultaneous use of more than 144 channels (depending on your
country regulations). The Receiver is provided with 2 antennas that constantly
monitor the incoming RF (radio frequency) signal and send only the stronger RF
signal to the AU-800R Receiver. Your AU-800 system is full of key features such
as AUTO-SCAN function, battery level monitoring and others.

AU-800H: It is a handheld transmitter with rubberised finished and level
hi-fi microphone capsule.

Depending on the options available your AU-800 system consists of:
