Features

RUGGED AND RELIABLE
The 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 reliability in multiple environments. And based on TDMA technology, the radio can work longer, up to 22 hours in digital mode.

CLEAR VOICE
With digital encoding and correction technology, voice is transmitted much clearer without background noise, even from a rather far distance with better audio quality.

ANALOG & DIGITAL DUAL MODES
The BD502i can support both analog and digital modes on the same device. You can switch between two operation modes very easily and it helps you to communicate with analog radios.

ANALOG & DIGITAL AUTO-DETECT
The BD502i 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, the user can easily reply to the call by push-to-talk. This is a real migration technology from analog to digital.

LONG WORKING TIME
Based on TDMA technology, the BD502i in digital mode can work as long as 16 hours @ 1500mAh or 22 hours @2000mAh in 5-5-90 mode.

RELIABLE AND DURABLE
The BD502i is compliant with MIL-STD-810 C/D/E/F/G and IP54.

ANTI-INTERFERENCE
Adopted digital encoding and error correcting module, the BD502i has 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 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.

VOX
When using a VOX earpiece, this feature allows you to activate the microphone via speaking volume, and free your hand from PTT.

SCANNING
Allows the BD502i to listen to communication activities on other channels.
