Increased Call Capacity with DMO 2-slot Operation, GPS Real Time Location, Secure Communications, Pseudo Trunk, Automatic roaming under IP Multi-site Connection System.
Analog, Digital and Mixed Modes
DP480/DP485 is able to detect signal type when receiving a call and automatically switch between analog and digital mode. The user can reply during the call hang time using PTToC. This feature improves migration from analog to digital.
DMO Support
Provide Direct Mode Operation in 2 slots increasing channel capacity without increasing channel frequency spectrum. Multiple Digital Signaling DP480/485 supports features such as Radio Check, Call Alert, Stun/Revive, Radio Kill, and Remote Monitor, which make the radio management easy.
GPS (Optional)
Integrated GPS enables real-time tracking of radio.
Digital Encryption
DP480/485 supports ARC 40-bit encryption, which guarantees communication safety and improves communication privacy. Encryption function provides further protection against over-the-air interception.
Multiple Emergency Alarm Modes
Emergency alarm/call can be sent to your team member by pressing the independent emergency button. It also supports lone worker, mandown.
Roaming
Support roaming while using the radio in an IP site connect system. Programmable Keys for Easy Operation There are three programmable keys to select most-used features.
Pseudo Trunk
Dynamic allocation of slot while using repeater mode. Improve channel utilization providing simultaneous communication in repeater mode.
