1. INTRODUCTION

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

Thank you for your purchasing the MOD-800 

LTO wireless system.

Your MOD-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 MOD-800 Receiver. Your MOD-800 system is full of  key features 
such as AUTO-SCAN function, battery level monitoring and others. 

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

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