BEST PRACTICES:
HIGH NOISE ENVIRONMENTS AND THE DIGITAL DIFFERENCE
To minimize or eliminate the impact of background noise
when using digital radios:
1. Place the microphone 1-2 " from your mouth.
2. Place the microphone facing your mouth.
(Microphone performance is maximized when the
audio is coming directly into the microphone and not
entering the microphone from the side or back.)
This also allows the APX noise cancellation microphone
on the back to reduce background sounds.
3. Speak in a clear and controlled voice to maximize audio intelligibility.
Digital Trunking Differences
• Wait for the talk permit tone (chirp) before speaking
• Audio delay – you will notice a delay between what you said and what others hear if another radio is nearby
• Proximity - you may hear and echo when two radios are too close together
• Hang-time – your radio continues to transmit for a second after PTT button is released
• Radio mics are sensitive and can pick up back-ground conversations
