Powerful radio solution:

One-touch alarm

The side button enables instant SOS activation – all same-frequency users receive alert tones while the transmitting unit only displays LED indicators (no audio exposure). This efficient operation delivers superior user experience and value.

Extended standby

Standard 7.4V 3200mAh battery provides up to 36 hours working time and 6 days standby – meeting prolonged communication needs.
Optional 1800mAh battery delivers 12 hours working time and 3 days standby for lower-usage groups.

Frequency & sub-tone encryption

When enabled, frequencies and sub-tones auto-encrypt – preventing accurate detection by scanners (DCS analog/CTCSS digital sub-tones). Ensures user privacy while avoiding channel interference.

Antenna with enhanced penetration

Custom low-impedance long antenna delivers stronger signal penetration – maintains clear audio during co-channel interference when paired with 5W transmit power. Optional extended high-gain antenna increases range by 30% for long-distance requirements.

Extra-large speaker

Features a 36mm large-size, 1W high-power speaker with optimally-proportioned acoustic chamber and anti-vibration plastic structure to ensure loud, intelligible audio – keeping communication smooth and uninterrupted.

Extended standby for longer use

The standard battery features a Micro charging port, compatible with 5V power adapters, power banks, and computers for uninterrupted calls and convenience – delivering an always-powered user experience.
