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 on 1 frequency at no extra costs or frequency license.

Digital/analog Dual Modes
BF-TD511 gives you a smooth transition from analog to digital.

Private Call, Group Call and All Call
the versatile calling functions bring more efficiency to your teamwork.

Long Battery Standard Time
BF-TD511 is a powerful radio with long battery life. (digital 22h& analog 16h)

Excellent Audio Quality
the AMBE3000 vocoder and FEC technology give BF-TD511 loud and clear digital audio.

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

Remote Kill/Revive
Such functions enable you to kill or revive a radio over the air. this greatly facilitates dispatching work and can be especially useful should a radio happen to be lost. You can easily remote kill the lost radio and confidential information can be kept from leaking out.

Radio Priority-based Interruption
this function enables a radio with a higher level to interrupt communications between radios with lower levels, giving higher priority to radios with higher levels. this means better dispatching efficiency.

Automatic Roaming (Programmable)
in an IP multi-site network, this feature enables BF-TD511 to automatically roam among all sites and stay connected, delivering more flexibility and efficiency.
