- Dual-channel signal reception with 100 selectable channels per channel
- Independent volume adjustment for each channel ensures higher precision and controllability, eliminating potentiometer resistance noise
- Features a lock screen function operated via function key combinations
- One-touch frequency scanning function enables intelligent searching for interference-free frequencies
- True diversity receiving system equipped with professional performance-grade phase-locked loop (PLL) circuit, combined with noise-locked squelch control and digital pilot tone technology. When the transmitter is turned off, the pilot tone control mutes the AF signal to suppress noise and mutes the corresponding receiver simultaneously, ensuring effective blocking of interference signals.
- LED display screen indicates battery level, operating frequency and channel for convenient management during use
- Fully automatic frequency scanning locks onto the cleanest available frequency in the working environment with high practicability
