HYT DMR digital radio PD785 400-470Mhz Hytera walkie talkie Portable radio PD78X PD-785 DMR transmitter Two Way Radio
Functions:
Highlights
UL913 and CSA Certificated Explosion-proof Safety
Hytera PD78X/PD78XG intrinsic safety radio is designed upon the requirements of USA UL913 and Canada CSA standard, the radio works safely in most hazardous environments with explosive gas and dust particles.
Reliable Quality
PD78X/PD78XG is strictly compliant with MIL-STD-810 C/D/E/F/G and IP67 standards, ensuring outstanding performance even in harsh environments.
Support MPT and DMR Trunking Modes
Upgrade software enables new features without buying a new radio could also be switched into MPT and DMR trunking modes with corresponding license a applied in the same hardware.
High Audio Quality and Assured Communication
Based on DMR Technology Benefitted from the latest digital DMR technology, PD78XG/PD78XG ensure your workers talk and hear clearly over excessive noise.
Ease To Use
With large PTT, volume, channel knobs and programmable buttons, PD78X/PD78XG are easy to operate even when wearing gloves. The PD78X/PD78XG with large and colour display(PD78XG only) and bright LED show status information at a glance.
Larger Li-Ion Battery capacity, longer cycle life
Equipped with 2400mAH and UL913/CSA certificated Li-Ion battery, PD78X/PD78XG provides with shift life of 18 hours under 5-5-90 duty cycle. And the battery life-span is longer as the charge/discharge cycles reduced.
Features:
Higher Spectrum Efficiency, Higher Channel Capacity
Benefiting from the TDMA technology, PD78X/PD78XG allows twice the channels based on the same spectrum resource. This is a big help to relieve the stress of increasing shortage in spectrum resource.
Dual Modes (Analog + Digital)
PD78X/PD78XG can operate in either analog or digital mode. It is compatible with the prevalent analog system, ensuring a smooth analog-to-digital transition.
Dual-slot Pseudo Trunk
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.
Secure Communication
Besides the basic encryption of the digital technology, PD78X/PD78XG provides enhanced encryption capability (such as 40,128, 256-bit encryption algorithm) and the Scrambler feature (selectable).
Data Services
PD78X/PD78XG supports data capabilities of sending Private, Group text message. It also supports Third Party to control the radio via Third party API (GPS, Radio Registration Services, Radio and Call Control, Telemetry*, Data Transfer*), via Telemetry control to radio.
Various Analog Signaling Types
PD78X/PD78XG supports various analog signaling types (HDC1200, DTMF, 2-Tone and 5-Tone), various squelch control types (CTCSS/CDCSS), thus providing higher function expansion capacity to the analog world.
Supplementary Services
PD78X/PD78XG supports supplementary services of Radio Check, Remote Monitor, Call Alert, Radio Enable and Radio Disable.
Enhanced Safety
Hytera PD78X/PD78XG provides a dedicated emergency button. In case of any accident, a press on the button will trigger an alarm and initiate a voice call to a pre-programmed work fellow or group. Built-in Man-down, GPS and Lone Worker functions are also a available with the digital portable.
Versatile Services
In addition to conventional communication services, PD78X/PD78XG features rich data services and selectable functions such as Text Message, Scan, Emergency, Man Down (optional), Auto Registration, High-speed Data Transmission and Lone Worker.
