Description

RUGGED AND RELIABLE
BD502 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, the radio can work longer, up to 22 hours in digital mode.

EXCELLENT PERFORMANCE
With innovative design, BD502 has a better performance than analog radios. An excellent receiving ability makes the communication range extend further. What's more, BD502 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
BD502 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
BD502 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, BD502 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
BD502 is compliant with MIL-STD-810 C/D/E/F/G and IP54.

ANTI-INTERFERENCE
Adopting digital encoding and error correcting module, BD502 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 BD502 listening to communication activities on other channels.
