Key Features

Ultra-Thin & Pocket-Sized Design

The handheld radio is manufactured with a slim 15mm (0.59 in) profile and a lightweight 103g construction, allowing it to be carried easily during long working hours. The compact design ensures that it can fit comfortably in pockets or small holders without causing inconvenience.

License-Free FRS Operation

The device operates on the FRS (Family Radio Service) frequency band, allowing communication to be used without requiring a license. Instant operation is provided right out of the box, which simplifies setup and makes it suitable for clinics, offices, and workplaces that require immediate internal communication.

Clear LCD Display

An integrated LCD screen is included to display important information such as battery level, channel number, and active functions. This visual interface allows the device status to be checked quickly, helping staff members stay informed during communication.

All-Day Battery Performance

A 1620mAh built-in rechargeable battery supports long usage periods, providing up to 18 hours of working time on a single charge. This extended battery capacity allows the radios to be used throughout an entire shift without frequent recharging interruptions.

VOX Hands-Free Communication

The VOX (Voice-Activated Transmission) feature enables hands-free communication. Once activated, voice transmission can be triggered automatically without pressing the push-to-talk button, which is particularly helpful in busy professional environments where hands are often occupied.

Type-C Charging Convenience

A Type-C charging port combined with a 2-in-1 charging cable allows two radios to be charged simultaneously. Faster and easier charging helps maintain operational readiness throughout the workday.

Emergency Alarm Function

An emergency alarm feature is integrated to provide quick assistance when required. By pressing and holding the designated button, both local and remote alarms can be triggered, allowing team members to respond rapidly during urgent situations.

Adjustable Squelch Control

The radio includes adjustable squelch levels (0–9) that help suppress background noise when no signal is detected. This function improves audio clarity and prevents unnecessary noise interference in environments with multiple electronic devices.

Channel Lock Protection

A channel lock feature prevents accidental channel switching while the device is being used. This ensures consistent communication between staff members without unintended interruptions.
