How to Set Up Group Call on the Retevis RB48 Pro

For construction foremen, site managers, and safety crews, clear and instant team communication isn't just convenient—it’s critical for safety, coordination, and productivity. The Retevis RB48 Pro professional two-way radio is engineered for these demanding environments, featuring a dedicated one-key group call function that lets an entire crew communicate simultaneously.This guide will walk you through setting up the group call feature on your RB48 Pro radios.

Why Group Call is Essential on a Construction Site 

Imagine coordinating a concrete pour, managing crane operations, or conducting a site-wide safety briefing. Yelling across noisy machinery is ineffective, and individual calls waste precious time. The RB48 Pro’s group call function solves this by allowing one transmission to reach every radio on your designated channel instantly. 

One-key group calling key advantages: 

• Instant safety alerts: Broadcast emergency stop or hazard warnings to the entire team at once.
• Efficient team management: Issue instructions to all subcontractors or specific trades without repetition.
• Seamless multi-level coordination: Maintain communication between ground logistics, basement construction workers, and top-floor workers.
