Analog and digital mobile radio
The MD625 can be configured in both analogue and digital channels. The radio automatically detects whether incoming calls are analog or digital, making migration to digital mobile radio much easier.
Hytera MD625
DMR mobile radio
Product description
With new software: As a result of legal patent litigations, the TDMA direct mode was removed for digital operation. With the Hytera patented Pseudo Trunking two parallel calls in direct mode are still possible.
Easy to operate and offering excellent value for money, the MD625 is a cost-effective yet powerful digital mobile radio, the ideal choice for transportation, agriculture, utilities and logistics users. A variety of interfaces and Bluetooth connectivity guarantee optimum usability. The display allows to show text messages and names for groups and other call participants.
Workforce Safety
Visible and easily accessible orange emergency button provided as a standard to initiate an emergency alarmand calls to other radios.
GPS module & Bluetooth functionality (optional)
The MD625 is able to upload its real-time position to AVL Applications if coupled with the optional external GPS module and antenna.
Operated via handheld microphone as standard, select the Bluetooth version to make the most of wireless accessory options, alongside a range of external switches and speakers.
Clear Communication
Delivered thanks to the latest audio processing technology and powerful in-built speaker, assisted with a 1.5" LCD display and three programmable buttons.
