Eartec XTSC4000SH 4-User Two-Way Radio System

Complete 4-User Two-Way Radio System for Team Coordination
The Eartec XTSC4000SH system is a robust four-user wireless communication solution designed for high-noise, high-activity environments. It combines four SC-1000 UHF radios with four XTreme Shell Mount PTT headsets to deliver crystal-clear, hands-free voice communication without the need for a base station. Whether on a construction site, at a live event, or managing operations in a warehouse, this all-in-one kit ensures your team stays connected and productive.

Simplex Mode Enables Seamless Group Messaging
The SC-1000 radios operate in simplex mode, allowing one user to broadcast a message to all team members simultaneously. This one-to-many transmission is perfect for task coordination and quick updates across teams. With 16 available channels and 38 digital privacy tones, interference is minimized and security is maximized, making this system ideal for larger teams or expanding operations.

Reliable UHF Range and Interference Protection
These professional-grade UHF transceivers offer up to 1 mile of communication range in open areas and excel at penetrating walls and structures. The inclusion of 38 privacy codes ensures that your transmissions remain secure, blocking outside interference and preventing unauthorized listening—especially valuable for sensitive communications in public or industrial areas.

Built Tough for Demanding Work Environments
Each SC-1000 unit features a durable polycarbonate shell, military-style belt clip, and rechargeable NiMH battery that provides up to 8 hours of continuous use. The units are lightweight but rugged enough for tough working conditions and designed for ease of operation with just two control dials: one for volume/power and one for channel selection. Voice annunciation clearly indicates the selected channel without needing to look at the device.

XTreme Headsets Built for Safety Gear Compatibility
This system includes four XTreme Shell Mount PTT headsets, engineered specifically for users wearing protective gear like bump caps or hard hats. The stainless steel spring backband and adjustable overhead strap provide a secure, comfortable fit even under safety helmets. Each headset features thick, gel-padded earcups for superior noise isolation and long-wear comfort, making them ideal for industrial use.

Hands-Free Communication with Push-to-Talk Control
The inline PTT button allows users to transmit quickly without fumbling for controls. This hands-free functionality is perfect for teams that need to focus on the task at hand while maintaining continuous voice communication. Whether you’re coordinating a tree care crew, managing an event setup, or operating in a noisy warehouse, the XTreme Shell Mount headsets make communication effortless and efficient.
