Holding Your Radio
The radio has two microphones: a top microphone for simplex dispatcher/private calls and a bottom
microphone for duplex telephone-like calls.
The radio is also equipped with an internal speaker for high audio (located at the middle of the unit)
and an internal earpiece for low audio (located at the top of the unit). The audio can be routed either to
the speaker or the earpiece using the Audio Toggle menu (
Menu → Setup → Audio → Audio
Toggle ) or the assigned One-Touch Button.
NOTICE: For best performance speak directly into the top microphone.
Simplex Calls
When using high audio, hold the radio a vertical position with its top microphone 5 cm to 10 cm away
from your mouth. Speak into the top microphone. Listen through the internal speaker. Keep the
antenna at least 2.5 cm from your head and body.
Duplex Calls
When using low audio, hold your radio as you would a telephone. Speak into the bottom microphone.
Listen via the earpiece. Keep the antenna at least 2.5 cm from your head and body.
Lapel/Shoulder Use
For Group and Private Calls turn your head towards your shoulder/lapel, and speak directly into the top
microphone. Listen through the internal speaker.
Speakerphone Use
Place your radio 30 cm to 60 cm away from you. In a noisy environment, move the radio closer to you
for better transmission.
