K520 gives you a smooth transition from the analog world to the digital.

Dual-Slot Direct Mode (DMO)
One frequency, two simultaneous calls. This doubles channel capacity, conserves spectrum—and keeps instructions flowing smoothly even at peak traffic, boosting team collaboration.
Selectable TX Power
Switchable 5 W (high) / 1 W (low). Up to 7 km line-of-sight range in open areas. Choose the level that fits the mission and stretch battery life.
Flexible Encryption
Supports both standard scrambling and **AES-256** to safeguard voice and data.
VOX 
Voice-activated transmit lets users keep both hands on the job—ideal for construction, logistics, outdoor rescue, and more.
Private Call / Group Call / All Call
Instantly establish one-to-one, team, or fleet-wide calls to match any operational scenario.
Lone-Worker Protection
If no key-press, motion, or PTT activity is detected within a preset interval, the radio triggers an alarm and sends location data to ensure rapid rescue.
Emergency Alarm
Press the dedicated emergency key to broadcast a distress alert to other portables or the dispatch console—critical for personal safety.
Channel Scan
Quickly locate an active channel during emergencies, speeding up contact and coordination.
Compact, Rugged Ergonomics
Tough housing with an anti-slip, ergonomically contoured FCR design. Lightweight for pocket, belt, or single-hand use—push-to-talk at the touch of one key.
