Switching Between Repeater or Direct Operation Button

The Repeater Operation increases the radio coverage area by connecting with other radios through
a repeater. The transmit and receive frequencies are different. The Direct or "talkaround operation"
allows you to bypass the repeater and connect directly to another radio. The transmit and receive
frequencies are the same.
Procedure:
Press the preprogrammed Repeater/Direct switch to toggle between talkaround and repeater
modes.

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.
