are heard in the mobile speaker and may also be retransmitted by both the Vehicular Repeater and Mobile
transmitters at the same time. Signals received by the Mobile receiver are heard in the mobile radio speaker and
are also retransmitted out of the Vehicular Repeater transmitter. When the SYSTEM repeat mode is selected, the
