DISCUS Operators Guide: A Comprehensive Manual

Introduction

DISCUS is designed for ease of use and efficient operation. This guide will assist you in getting started and troubleshooting common issues.



Important Tips

  • Jack Connection: Ensure the plug is fully seated for proper operation.
  • Headset Requirements: DISCUS requires a NATO wired headset. If using a push-to-talk (PTT), it must also be NATO wired.

Initial Setup Guide

Step #1: Remove the Battery Cover

Slide the battery cover back toward the negative side of the embossed battery and tilt it upward.

Step #2: Install the Battery

Insert the CR-123 battery with the Negative (-) side toward the retention spring. A low battery LED will indicate when it's time to change the battery.

Step #3: Replace the Battery Cover

  • Align the leading edge with the covered threaded insert.
  • Place the cover on both sides along the rail.
  • Slide the cover forward until you hear a click.

Step #4: Connect Your Headset

Install your headset into the TJ 101 port. The weather sealing boot may require extra force. 

This is the most common user error leading to low/no audio.
