Hytera PD402i DMR Digital Portable Two-Way Radio (UHF 400–470 MHz)

The PD402i UHF is a no-display radio built for environments where carrying a screen makes no practical sense. On a manufacturing floor, in a warehouse, or in a multi-story facility, workers need a channel knob, a PTT, and nothing else between them and the job. The interface is deliberate: a channel selector knob, tactile PTT button, and two programmable side buttons. Maintenance technicians, floor supervisors, and security personnel operate it without shifting attention away from the work in front of them.

UHF at 400–470 MHz is the practical standard for indoor operations. At this frequency range, radio waves penetrate concrete block walls, steel shelving, floor slabs, and mechanical equipment — the physical obstacles that degrade VHF performance in dense building environments. A single PD402i UHF unit covers multiple floors and spans of a building that would require a repeater with a lower-power radio. For large multi-floor facilities — distribution centers, manufacturing plants, hospitals, hotels — UHF is the band most installers default to without hesitation.

The 1500mAh Li-ion battery runs 16 hours in digital mode at a 5-5-90 duty cycle. Workers on a full day shift, including overtime, carry the radio through the entire working day without a midday charge. The optional 2000mAh battery extends that to 22 hours in digital mode — practical for operations running back-to-back shifts or facilities where radios are shared between workers without a guaranteed gap for charging.

For multi-building campuses with interior dead zones, the PD402i supports DMR Tier II repeater infrastructure. Roaming lets a worker move between building wings or floors without dropping active calls — the radio connects to the strongest available repeater automatically. Pseudo-trunking routes each call to whichever of the two DMR timeslots is free, preventing channel congestion during peak morning and shift-change periods when many radios are active simultaneously.

The PD402i UHF carries an IP55 rating confirmed by Hytera US, providing protection against directed water jets — a level above the IP54 found on most commercial portables. This matters specifically for manufacturing environments with periodic hose washdowns, food processing facilities, and outdoor loading dock areas where the radio is routinely exposed to water. Both programmable side buttons support dedicated emergency alarm configuration: pressing either sends an immediate alert carrying the radio’s ID to the dispatcher and pre-programmed units, enabling fast incident response for lone workers in hazardous areas.

Operation of the Hytera PD402i UHF on licensed frequencies in the United States requires an FCC Part 90 license. This applies to commercial and business radio use across manufacturing operations, warehousing, distribution, healthcare facilities, educational institutions, and security teams operating on private licensed UHF frequencies in the 400–470 MHz band.

As an authorized Hytera dealer, AXDIGITAL assists customers throughout the licensing process — from identifying the correct UHF frequencies for your site to preparing and submitting the FCC Part 90 application. UHF is the recommended band for indoor multi-floor facilities; our team provides guidance on frequency selection based on your building type and existing equipment.

The PD402i-U1 is FCC Part 90 certified. For organizations coordinating communication across multiple departments or floors, we provide frequency coordination recommendations to prevent channel interference.
