A rugged and robust device with high performance but simple to operate will make everything easier to handle.

Hytera understands customers' requirements and meets them all in one, also with lightweight, easy-operation, excellent performance, long-time working and reliability. So we redefine a business radio with Hytera digital technology, quickly responding to what you need.

RUGGED AND RELIABLE

Hytera BD502i is designed and tested to meet Military Standards 810 C, D, E, F and G, including temperature shock, vibration, high & low temperature and humidity. IP54 dust- and water-proof design guarantees the reliability in different environments. And based on TDMA technology, this Hytera portable radio can work longer, up to 22 hours in digital mode.

EXCELLENT PERFORMANCE

With innovative design, Hytera BD502i has a better performance than analog radios. An excellent receiving ability makes the communication range extend further. What's more, Hytera BD502i is a DMR digital radio with good performance of anti-interference, providing purely stable communication.

CLEAR VOICE

With digital encoding and correction technology, human voice is transmitted much clearer without background noise, even from a rather far distance.This is a new experience of better audio quality.

ANALOG & DIGITAL DUAL MODES

This Hytera UHF radio can support both analog and digital modes on the same hardware. You can switch between two operation modes very easily and it helps you to communicate with analog radios.

ANALOG & DIGITAL AUTO DETECT

This Hytera portable radio can detect the signal type when receiving a call, then automatically switches between analog mode and digital mode to get the voice out of the speaker. During the call hang time, users can easily reply the call by push-to-talk. This is a real migration technology from analog to digital.

EXTENDED TALK RANGE

Greatly extend your talk range based on Hytera's innovative technology.

LONG WORKING TIME

Based on TDMA technology, this Hytera UHF radio in digital mode can work as long as 16 hours @ 1500mAh or 22 hours @2000mAh in 5-5-90 mode.

CLEAR VOICE

Excellent audio quality comes from the DMR digital technology, which makes the communication more reliable.

RELIABLE AND DURABLE

This Hytera portable radio is compliant with MIL-STD-810 C/D/E/F/G and IP54.

ANTI-INTERFERENCE

Adopting digital encoding and error correcting module, this Hytera UHF radio can have a better ability to avoid signal interference on the same frequency.

DMR SIGNALING

With DMR signaling, transmitting group calls, private calls and all calls with PTT ID becomes quite easy.

REPEATER MODE OPERATION

Utilize a DMR Tier II repeater to extend your communication range.

VOICE ANNOUNCEMENT

Channel number announcement helps you to switch channels quickly and correctly, even in blindness operation.

DUAL CAPACITY DIRECT MODE

In direct mode, you can have two voice calls simultaneously from DMR two time slots. This feature can be used to increase the radio capacity at no extra costs or frequency license.

VOX

This feature allows you to activate the radio microphone via speaking volume, and free your hand from PTT.

SCANNING

Allow the Hytera UHF radio listening to communication activities on other channels.
