Setting Ambient Noise Level
Ambient noise is the ambient noise of the environment the radio is being used in. Therefore, if the
radio is being used in a very noisy environment, then the ambient noise level should be set to High.
This lowers the mic gain on the radio and thus, reduce the noise from the surrounding environment.
A low ambient noise level increases the mic gain, and allow the receiver to hear clearer audio.
The microphone sensitivity of DTR Series radios can be adjusted to accommodate varying levels of
background noise. The radios' internal microphones and their accessories' microphones can be
adjusted independently. Use the Low setting to decrease the microphone sensitivity for high levels of
background noise, or High for quieter environments.
