The Kirisun DP405 is a professional, commercial-grade dual-mode digital and analogue handheld transceiver. Built using the DMR Tier II / TDMA protocol, this non-display radio serves as a highly robust and cost-effective solution for enterprises transitioning from older analogue communication systems to digital airwaves. It is widely deployed across retail operations, warehousing, security grids, and heavy production environments.
| Mixed-Mode Standby & Auto-Detect | Automatically detects whether an incoming signal is digital or analogue and switches to the appropriate operating mode. This allows users to communicate with both analogue and digital radios without manually changing modes during normal operation. |
| Dual-Timeslot Direct Mode (DMO) | Uses two-slot TDMA technology to support two separate communication paths on a single 12.5 kHz frequency in direct mode, increasing channel capacity without requiring a repeater. |
| ARC 40-Bit Digital Encryption | Supports ARC 40-bit digital encryption to provide an additional layer of privacy for operational radio communications and help reduce unauthorised monitoring. |
| Pseudo Trunking | Automatically identifies and allocates an available time slot during digital operation, helping improve frequency utilisation and communication efficiency during periods of higher radio traffic. |
| Powerful 1W Audio Output | A 1-Watt internal loudspeaker combined with DMR digital audio processing and error correction provides strong, intelligible voice communication in noisy workplaces such as factories, workshops and job sites. |
| Remote Fleet Management | Supports digital management functions including Radio Check, Call Alert, Stun/Revive, Radio Kill and Remote Monitor, providing greater control over lost, unreturned or compromised fleet radios. |
| Reinforced Antenna Protection | A raised protective collar around the antenna base helps protect the antenna connection and SMA connector from impact and stress during demanding everyday use. |
