Features:

• Appearance design (rugged and compact): With rugged and professional design to provide with reliable and durable quality!
• 1024 channels and 64 zones: 1024 channels and 64 zones to realize high-efficiency channel and group configuration and management.
• Dual capacity direct mode(DCDM): Provide direct mode operation in 2 time slots to increase channel capacity without increasing channel frequency spectrum.
• Digital or analog mode: Supports both digital and analog mode to provide cost-effective way for users to migrate from analog to digital or switch between the two modes for communication with analog radios easily.
• Noise cancellation: Using advanced narrowband voice encoding and digital error correction technologies to provide superior audio quality while in noisy environments or at the edge of the coverage area. The use of AGC technology has also greatly optimized the voice receiving effectiveness.
• Built-in 1W speaker to ensure superb clear and powerful audio output, to provide with reliable instant communication.
• Voice encryption: Digital voice encryption to guarantee safety communication and maintain the privacy in your conversation.
• Output Power: With different power module 50W/60W for UHF/VHF and 25W for UHF/VHF optional.
• Supports both digital and analogue, programmable side keys, high and low power selective, VOX hands-free voice control,
• TOT time-out-timer, transmission limit selective,
• BCL busy channel lock, emergency alarm, talk around; battery save mode and programming password etc.
• Digital functions: Individual call, group call, all call, voice encryption, remote emergency alarm, remote monitor, remote stun, remote kill, remote activation and SMS function etc.
• CTCSS and DCS.
• Digital and analogue mixed modes: It is able to auto detect signal type when receiving a call and automatically switch between digital and analogue mode for receiving. The user can reply during the call hang time by using PTT, this feature improve immigration from analogue to digital. 
• Battery save and low battery alert: It will be helpful for battery save once it has been activated, and will broadcast alert when battery life is low.
• Emergency call: One-touch emergency alarm can be sent to other radios with the pre-programmed button, to improve worker safety and emergency response time.
• DMR: DMR signalling enable individual call, group call and all call, supports DMR Tier 2 repeater to extend coverage.
• Professional design with conventional scheme: Professional conventional scheme design to provide better anti-interference ability to perform in tough and noisy conditions.
• SFR(Single frequency repeater) optional: With SFR(single frequency repeater) mode available to allow users to use it as a repeater to enlarge the communication range in some scenarios flexibly.
• High standard AES256 voice encryption optional: Provide high standard voice encryption AES256 for high confidential communication such as military, police, government projects etc.
