License‑Free PMR446 Operation

Uses the harmonised 446 MHz band — no frequency license, no call charges. Works out of the box with any PMR446 radio across brands.

Three times the channels of standard PMR446 radios. Organise talk groups for different departments, floors, or shifts. Each zone holds up to 16 channels.

Optimised Coverage

Ideal for malls, supermarkets, stores, and warehouses. Up to 8 km range in open areas; reliable multi‑floor penetration indoors.

While the license‑free variant transmits at 0.5W, the radio supports 1W and 3W power levels when programmed for licensed frequencies, giving you flexibility in future.

Clear 0.5W Audio

A powerful speaker delivers crisp voice even in noisy environments. The microphone's noise suppression filters out background clamour.

Hytera HYT-S31 LF is a next‑generation license‑free PMR446 portable radio that combines the simplicity of a classic walkie‑talkie with modern technology like Bluetooth, USB‑C, and extended battery life. It is designed for businesses that need instant, reliable, and cost‑free communication across shops, malls, warehouses, and supermarkets — without the burden of licences or contracts.

More Channels, Better Organisation: Unlike most license‑free radios that stop at 16 channels, the HYT‑S31 LF provides 48 channels arranged in 3 zones. This allows you to dedicate distinct channels to different departments, such as security, store floor, and warehouse, minimising cross‑talk and confusion. The simple rotary channel selector makes operation intuitive for all staff.

Industry‑First Bluetooth & USB‑C: Hytera brings enterprise features to the license‑free segment. Bluetooth 5.0 enables wireless programming and configuration via a laptop. The USB Type‑C port charges the 2200 mAh battery in a few hours, and because it's a universal standard, you never need to hunt for a special charger. These features reduce total cost of ownership and simplify fleet management.

Built for the Real World: The HYT‑S31 LF weighs just 145 grams and has a modern, slim profile that fits comfortably in a pocket or on a belt. It operates reliably from -10°C to +55°C, making it suitable for cold storage rooms, loading bays, and outdoor patios. The IP54 rating provides protection against dust and water splashes, while MIL‑STD‑810G testing confirms its durability against drops and vibrations.

Extended Talk Time: The 2200 mAh Li‑Polymer battery delivers up to 27 hours of operation at 0.5W, 22 hours at 1W, and 15 hours at the licensed 3W setting. A full working day — and beyond — is comfortably covered. The battery life, combined with USB‑C convenience, keeps your team connected without interruption.

Who Uses It? Shopping malls, retail chains, supermarkets, warehouses, hospitality staff, event management, and small businesses that need instant, license‑free coordination. The HYT‑S31 LF’s 48 channels and clear audio make it a versatile tool for any on‑site team.
