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.
