SECTION 1. INTRODUCTION
The DX340|HD provides secure communication among the coaching staff.
Spotters in the press box can communicate with offense “O” only, defense “X” only or “ALL” coaches via headsets
connected directly to the base station.
Coaches on the sideline wear beltpacs with headsets to communicate with each other and the spotters.
Beltpacs can be set up for communication with any combination of offense, defense and ALL.
This manual includes detailed setup and operating instructions for your DX340|HD system.
