HiFi Microphone
Base
The base is the part of the HiFi Microphone (HiFi Mic) that is mounted in the vehicle and physically
connects to the 4RE DVR and the antenna.
The base serves the following purposes:
l Synchronizes with the transmitter so the DVR can record audio transmitted by the HiFi Mic (see
page 30)
l Charges the transmitter while it rests in the base (see page 31)
l Stores the transmitter while not in use (see page 14)
Features on the base include:
l Status LEDs (see page 16)
l DVR cable connection (see page 17)
l Antenna connection (see page 16)
l Contacts for charging and syncing with the transmitter (see page 16)
Note: A version of the base exists that only serves as a charger for the HiFi Mic.
This version of the base is not used in the vehicle. For information about the charge-
only base, contact your Motorola Solutions representative.
Status LEDs
The HiFi Mic has status LEDs on both the base and the transmitter. You can use these LEDs in
conjunction with the icons on the display to determine the status of the HiFi Mic.
