Monitor Feature
The monitor feature ensures 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.
