Feature:
- 1.Enter the digital age in style with the Retevis RT81 DMR Digital Portable Two Way Radio, The RT81 offers amazingly clear, full quieting digital voice communication.
- 2.RT81 has two modes of digital and analog, 2 regions, select 32 channels, It uses digital mobile radio(DMR)Tier 2 standard protocol It is compatible with the popular series Tier I and II .
- 3.RT81 after strict waterproof and dust test,IP67 waterproof and Dustproof, Strict shell structure and material, so that the use of RT81 in a complex environment to ensure the normal use of radio.
- 4.High power, RT81 equipped with high power emission, Center frequency point test 10W power, increase the communication distance.
Digital Mode & Analog Mode Combined
RT81 has two modes of digital and analog,not only can be compatible with the existing communication system simulator,but also can comply with the future digital trend, saving the cost of repeated procurement and equipment replacement.
Superior Audio Performance
DMR digital technology provides better noise rejection and maintains voice quality at the farthest edge of the transmission range.
Super Long-distance Communication
RT81 is equipped with 10W high power , which makes long-distance communication more distant,clear.
IP67 Waterproof & Dustproof
Excellent IP67 waterproof performance is born for a wide range of complex environments.
Multiple Call Modes
With single call,group call,and multiple call modes,RT81 adapt to complex and variable communication environment. Each machine has an ID, which can call a designated person, or can be freely grouped to enable members of the group to talk.
Digital Encryption
Digital encryption makes your call more secret (RT81 encryption is only available among RT81).
Large Capacity Battery
Long standby, long use time. Large-capacity battery have been guaranteed to last for a long time, and TDMA digital technology can increase battery life and increase usage time by 40% over analog radios,which allows RT81 to gain more woring time.
This radio is Suitable for storage, wharf, construction site, tourism, hotel, logistics, factory, big warehouse, church event, etc. and hard wet working environment, which is your essential equipment for work.
