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+2TMÂ 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.
