License-Free FRS Operation

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.
