Belfone Dmr Tier 2 Digital Two Way Radio Walkie Talkie with GPS Voice Recording (BF-TD512)

Product Description

Product Description
DMO Pseudo
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 TDMA two timeslots, which means two communication paths on 1 frequency at no extra costs or frequency license.
Digital/analog Dual Modes
BF-TD512 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 Standby Time
BF-TD512 is a powerful radio with long battery life. (digital 22h& analog 16h)
Excellent Audio Quality
The AMBE3000 vocoder and FEC technology give BF-TD512 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.
Personnel Safety
If some worker slips or falls, the man-down function will automatically activate and transmit a signal to his colleagues for help. Built-in Lone Worker and Emergency Alarms are also available in case of any accident.
Automatic Roaming (Programmable)
In an IP multi-site network, this feature enables BF-TD512 to automatically roam among all sites and stay connected, delivering more flexibility and efficiency.
