Trunking Mode (TM)
It can support PDT/DMR/NXDN digital trunking communication system service, realizes voice single
call, group call, broadcast call and rich trunking communication functions.
Conventional mode (DM/RM)
Fully support digital and analog services in the direct (DM) mode;
Fully support digital and analog services in the relay (RM) mode;
Adopts ARC4 & #AES256 encryption to secure communication privacy and optimize information
safety.
Single Frequency Repeater (SFR) is a technology that uses TDMA technology to rebroadcast two
way radio transmissions on the exact same physical frequency.
It can simultaneously receives and transmits at the same time, on the same frequency.
It does this by utilising DMR’s two time slots concurrently. The SFR receives on one time slot, whilst
transmitting on the other.
It can support PDT/DMR/NXDN digital conventional, Trunking standard communication protocol,
convenient to meet the different needs of customers use environment and requirements to enable
users to smoothly transition from analog communication system to digital communication system.
Support Bluetooth 4.2 standard access, support Bluetooth write frequency and Bluetooth call, the
function makes the versatility of the product more extensive.
Support GPS/Beidou positioning, which can be realized GPS/Beidou position information
transmission, combined with command and dispatch software, can be intuitively view the location of
people on the map and make voice calls with them.
The quality of the radio meets the national military standard and the IP67 industrial protection
standard, thus ensuring that the product structure is sturdy and durable, wear-resistant, antiaging,
and can exert excellent performance in a variety of harsh working environments.
Man-Down is a tilt-switch inside the radio that automatically sends an alarm signal if the radio is
tipped on its side for more than a preset period. The radio usually beeps to warn the user that the
alarm signal will be sent if the radio is not positioned upright again.
The purpose of the "man-down" feature is to protect lone workers, so if someone was to fall over
incapacitating them, their radio would send out an alarm warning other users or the control center,
who can then send for help.
