Hytera BD502i Portable Radio Digital DMR Analog UHF 400-470MHz

The Hytera BD502i is a compact, rugged UHF portable two-way radio engineered for commercial DMR deployments where reliability, audio clarity, and operational simplicity are essential. Operating across the 400–470 MHz UHF band in both analog and DMR digital modes, the BD502i delivers 48 programmable channels, an advanced audio equalizer, and up to 16 hours of battery life on a single charge. MIL-STD-810G and IP54 ratings ensure the radio holds up in demanding field environments, while DMR Tier II repeater support, pseudo-trunking, and one-touch emergency calling make it a practical choice for facilities management, manufacturing, hospitality, construction, and public-venue operations where dependable team communications are non-negotiable.

Key features & benefits

• Dual-Mode Analog and DMR Digital Operation — Seamlessly switches between analog and DMR digital modes, protecting existing analog infrastructure investments while enabling a phased migration to digital communications.
• 48-Channel Capacity — Supports up to 48 channels, providing ample capacity for multi-department or multi-site operations without the need for frequent reprogramming in the field.
• Audio Equalizer with Low, Mid, and High Frequency Adjustment — The built-in audio equalizer tunes low, mid, and high frequency gain to optimize voice intelligibility whether operating in a quiet office, a noisy warehouse floor, or an outdoor construction site.
• Audio Channel Announcement — Voice announcements confirm the active channel number audibly, enabling fast and accurate channel switching even in low-visibility or high-distraction environments.
• DMR Tier II Repeater Support with Pseudo-Trunking — Native DMR Tier II repeater compatibility extends talk range across large facilities or campuses. The pseudo-trunking feature automatically selects the available digital timeslot, improving call connectivity and maximizing spectral efficiency.
• One-Touch Emergency Alarm — A programmable button triggers an instant emergency alarm to other radios on the network, supporting faster incident response and improving worker safety in lone-worker or high-risk environments.
• MIL-STD-810G and IP54 Rated Construction — Tested to MIL-STD-810G standards for shock and vibration resistance, and rated IP54 for protection against dust ingress and water splashing, making the radio suitable for demanding commercial and industrial daily use.
• 1500 mAh Lithium-Ion Battery with Extended Runtime — The high-capacity 1500 mAh Li-Ion battery delivers up to 16 hours of operation in digital mode and up to 12 hours in analog mode, supporting full-shift use without mid-day recharging.
• VOX Hands-Free Operation — Voice-activated transmission is supported on the radio itself as well as on compatible external earpiece and microphone accessories, freeing operators' hands for task-critical work.
• Channel Scanning — Scanning capability allows users to monitor communication activity across multiple channels, ensuring important traffic is never missed in dynamic operational environments.
