HD1 dual band digital radio uses Digital Mobile Radio (DMR) Tier 2 Standard protocol.
Compatible with Motorola TierⅠ&Ⅱ.
Compatible with any existing analog two-way radio operating on the supported UHF and VHF frequencies for easy migration to digital
technology. And almost all the operations can be done via radio keypad.
