DMR True 2-Slot ● True IP67 Waterproof
With this feature, the free slot can be allocated to a member that needs to communicate, effectively enhancing frequency efficiency and allowing you to communicate timely under emergency situations.
True IP67 Dustproof and Waterproof
Radio body sealed fully to deliver IP67 waterproof and dustproof, which using glues and silica gel ‘s seal ring in radio’s speaker, knobs, PTT Key, chassis, microphone jack and screw hold, etc.
Higher Spectrum Efficiency, Higher Channel Capacity
Benefiting from the TDMA technology, DM-R88/R89 allow 2 channels based on the same spectrum resource at the same time. This is helpful to relieve the stress of increasing shortage in spectrum resource.
Digital voice makes your communication clearer and stable
With the advanced technology of narrowband voice coder and decoder and digital correction technology, either you are in the noisy environment or at the edge of communication coverage,DM-R88/R89 can always offer you a clear and stable voice quality.
DM-R88/R89 has got rich data services and selectable functions such as Text Message, Scan, Emergency alarm, Man Down (optional), High-speed Data Transmission and Lone Worker, etc.
Dual Modes (Analog + Digital)
DM-R88/R89 can operate in either analog or digital mode. It is compatible with the prevalent analog system, ensuring a smooth analog-to-digital transition.
Longer Battery Duration, Longer Working Time
Compared with analog radio, DM-R88/R89 can enhance more than 40% working time.
DM-R88/R89 have passedDMR IOP test by lab, which means it can compatible with Motorola or HYTERA DMR radios completely. With CE and FCC certification, DM-R88/R89 have been sold to many European and America countries and get a pretty good reputation from our customers and users.
