The full parameter table below is taken from the official datasheet. The PDF version — with dimension drawings and the complete standard-compliance table — is released on request, so we can send the exact revision your project needs.
RS3100 DMR Repeater — Same Frequency Repeating Mode (EN, 1 page)
Overview
A portable same-frequency repeating DMR repeater. Same-frequency repeating needs no split-frequency setup, and the 90 ms forwarding delay keeps conversation natural. With a 25000 mAh battery it holds 72 h standby and more than 12 h continuous transmission, which suits events, emergency drills and temporary command posts where a mast or back-to-back site would be impractical.
- Same-frequency repeating — no split-frequency pair to set up on site
- 90 ms forwarding delay for natural conversation
- Supports analog and DMR modes
- Touch screen showing time-slot status, battery level, charging status and alarms
- Built-in 25000 mAh battery: 72 h standby, > 12 h continuous transmission
- High-sensitivity receiver with digital error correction for noisy environments
- Modular design with independent receive unit for improved reliability
