Monitor Feature

The monitor feature is used to make sure that a channel is clear before transmitting.
The lack of static on a digital channel when the users switch from analog to digital radios is not an
indication that the radio is malfunctioning.
Digital technology quiets the transmission by removing the noise from the signal and allows only the
clear voice or data information to be heard.
