Eartec XTSC4000IL 4-User Two-Way Radio System

Complete Four-User Wireless Communication Kit for Demanding Environments
The Eartec XTSC4000IL is a four-user wireless communication system combining SC-1000 UHF radios with rugged XTreme Inline PTT headsets. Designed for hands-free communication in high-noise environments, this kit offers reliable team coordination across construction zones, industrial facilities, outdoor events, and more. With no base station required, users can communicate instantly right out of the box—perfect for fast-paced work environments.

Simplex Mode Enables Group-Wide Communication
Operating in simplex mode, the SC-1000 system ensures that when one user transmits, all others on the same frequency receive the message simultaneously. This makes the system ideal for group coordination where timing and clarity are critical. Teams can add more SC-1000 radios without system modification, allowing for scalable communication across multiple departments or job sites.

Durable Radios with Reliable Power and Controls
The SC-1000 radios feature a high-impact polycarbonate housing and military-style belt clip to withstand daily use in tough conditions. With 500mW of output power, each unit offers up to a 1-mile range and delivers strong UHF signals that penetrate through walls and steel structures. The radios are powered by rechargeable NiMH batteries that offer up to 8 hours of use and recharge easily via the included desktop charging base.

XTreme Headsets Built for Hard Hat Compatibility
Included in this kit are four XTreme dual-ear headsets with inline push-to-talk functionality. These heavy-duty headsets are built with a stainless steel spring backband and an overhead Velcro strap to fit securely with hard hats and bump caps. The padded, gel-filled earcups provide superior comfort and effective passive noise reduction, making them ideal for all-day wear in noisy settings.

Enhanced Audio Performance and Privacy Protection
The XTreme Inline PTT headsets feature noise-cancelling microphones that reduce ambient sound for clearer transmission. Meanwhile, the SC-1000 radios include 38 digital privacy tones to ensure secure transmissions and reduce interference from neighboring systems. Voice annunciation confirms channel selection through the headset speaker, removing the need to look at the device while operating.

Easy Setup With Expandability for Growing Teams
Getting started is simple—just power on the radios, select your preferred channel, and connect your headsets. With 16 channel combinations and digital tone matching, you can customize your communication system to your exact team size and layout. Whether you're adding this to an existing setup or starting fresh, the XTSC4000IL is designed to scale with your workflow.
