Intrinsically Safe Full Power Digital Radio


PD78X/78XG adopts a 1.8-inch high resolution color transflective LCD display, allowing good visibility even under outdoor strong light. In addition to conventional communication services, PD78X/78XG(UL913) features rich data services and selectable functions such as Text Message, Scan, Emergency, Man Down (optional), vibration Auto Registration, High-speed Data Transmission and Lone Worker.

  • 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.
    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.
    PD78X/78XG in this document are intrinsically safe, they are different from the conventional types.
