Hytera’s BD502i two-way radio is the compact device that provides a professional communication in easy to operate way. Today, communication tool is the key to improve the efficiency. When we ask for clear voice, it means a reliable talk that’s easy to hear and understand. Long battery life helps you to avoid losing contact. A rugged and robust device with high performance but simple to operate will make everything easier to handle.
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
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.
