Highlights

Small Size and Lightweight

Small enough to be held comfortably in your hand and light enough not to be a burden.

IP54 Dust & Water Protection

With lP54 protection, this smart and compact radio is built to last and to challenge all kinds of tough communication environments.

Radio Priority-Based Interruption

This function enables a radio with higher level to interrupt communications between radios with lower levels, giving higher priority to radios with higher levels. This means better dispatching efficiency.

A Long Battery

BF-TD446 can function for longer than any conventional analog radios. Battery life is one less thing to worry about!

Scan Monitor (programmable)

At a convenient push of a button you can monitor all the conversations on your channel, or you can scan conversations on different channels.

Excellent Audio Quality

Excellent digital audio quality comes from the AMBE+2TM vocoder and FEC technology

Private Call, Group Call and All Call

The versatile calling functions bring more efficiency to your teamwork.

Transmit interrupt

This function enables a supervisor to interrupt a radio conversation in order to clear a channel for more important communications.

DMO Pseudo Trunk

The user can choose slot 1 or slot 2 for communications. When one slot is occupied, the radio will automatically switch into the free slot. Frequency efficiency is greatly increased.

DMO True 2-Slot

In direct mode, this radio supports two voice calls simultaneously due to DMR two timeslots, which means two communication paths at 1 frequency with no extra costs or frequency license.

Digital/Analog Dual Modes

Receive both analog and digital signals on a single channel and can automatically switch into the needed mode for efficient communications.
