Kirisun DP485 Walkie Talkie
Kirisun DP485
The Kirisun DP485 is a future-proof DMR digital two-way radio. Based on TDMA dual-timeslot technology, this DMR radio delivers reliable and clear communication. It’s suitable for whether you’re directing traffic police, managing meetings, or operating a hotel.
Main features
Dual-Slot DMR with Analog/Digital Auto-Scan
Spectrum efficiency is at the heart of any excellent DMR radio. In repeater mode, the DP485 creates two independent communication paths on a single 12.5 kHz channel, instantly doubling user density without additional licensing fees. Each area can be set to pure analog, pure digital, or auto-scan mode. Security personnel using analog radios can continue to communicate seamlessly, while new employees enjoy clear digital communication.
AES-40 Encryption with ARC Algorithm
Both voice and data are encrypted with a 40-bit rolling key, featuring color-coded authentication and over-the-air re-key functionality. News teams and Senate staff rated the DP485 as the Kirisun radio of choice for secure field reporting.

Optional 400 Hours of Recording
A micro-SD card slot under the battery cover stores timestamped WAV files containing caller ID, GPS location, and channel name.
High-precision GPS/BeiDou
Location updates every 1-30 seconds, viewable on a 1.3-inch display, and can be exported to Kirisun DS5500 dispatch software. Facility managers can track porters across a 500-acre campus and set up geofencing to restrict access; outdoor schools can record activity tracks to ensure student safety.
Smart Battery & Charging
A supplied 2000 mAh Li-ion battery yields 14 hours of digital operation (5-5-90). A 30-minute top-up in the optional KSC-52D intelligent charger restores 50% capacity. Batteries are keyed to prevent third-party cloning, ensuring every DMR radio meets type-approval parameters.
