Hytera S1 Pro – Stylish and Compact Professional DMR Radio

The Hytera S1 Pro proves that a professional two-way radio does not have to be bulky or look like a traditional industrial communications device. Measuring only 20 mm in thickness and weighing just 135 grams, it can be carried comfortably throughout even the longest working shifts.

The distinctive design of the S1 Pro is inspired by the symmetry and clean lines of the classical Greek Doric order. The result is an exceptionally elegant and discreet radio, ideal for hotels, restaurants, retail stores, event venues, hospitality businesses, golf courses and other professional environments where staff appearance is an important part of the customer experience.

Despite its compact dimensions, the Hytera S1 Pro is a fully featured digital DMR two-way radio, supporting both digital and analogue operation. It can therefore be used as part of a modern DMR radio system while remaining compatible with existing analogue radios during a gradual system upgrade.

Clear communication in noisy environments

The advanced AI-based Noise Cancellation system can reduce surrounding noise by up to 30 dB, delivering clearer voice communications in busy venues, entertainment areas, crowded workplaces and environments with loud background music.

The integrated Whisper Mode allows the user to speak quietly while still being heard clearly by the receiving party. This makes the S1 Pro particularly suitable for hotels, restaurants, conference venues and other environments where discreet communication is essential.

OLED display and easy radio management

The clear 1.3-inch OLED display provides instant access to channel information, operating status, battery level and other essential information. Custom radio and channel names can also be created, making each radio easier to identify and operate.

Using the Hytera Radio App and Bluetooth connectivity, users can program the radio, back up frequency information and manage its configuration. The innovative AirClone function allows configuration data to be transferred wirelessly from one S1 Pro radio to multiple units, significantly reducing the time required to set up a professional radio fleet.

Long battery operating time

The integrated 2200 mAh Li-Polymer battery provides up to 16 hours of operation at the maximum 3 W transmission power, or up to 19 hours when operating at 0.5 W. Standby time can reach up to 360 hours.
