Product Overview
The headset features an external antenna, a microphone boom, and a battery slot. The volume buttons are orange on the host headset and black on the remote headset. The ENC (Environmental Noise Cancellation) switch is located on the side of the headset.
First Use and Setup

- Connection: Host and remote headsets are pre-paired by default. They will automatically connect when powered on. Remote headsets will play a "Connected" voice prompt upon successful connection.
Operation
Microphone Control
The microphone boom acts as a mute switch. When the boom is placed at a 45-degree angle, the microphone is muted (indicator shows red light). Pushing the boom forward to 45 degrees turns the microphone on (indicator shows green light).
Volume Control
Use the "+" or "-" buttons on the side of the headset to adjust the hearing volume. There are 5 levels of volume, with level 3 being the default. The headset remembers the last volume setting.
ENC (Noise Cancellation)
Environmental Noise Cancellation is enabled by default when the headset is powered on. You can manually toggle it off or on by clicking the ENC switch button.
